(e) The fact that any person charged with a violation of this subsection (1) is or has been entitled to use one or more drugs under the laws of this state, including, but not limited to, the medical use of marijuana pursuant to section 18-18-406.3, C.R.S., shall not constitute a defense against any charge of violating this subsection (1).
(f) “Driving under the influence” means driving a motor vehicle or vehicle when a person has consumed alcohol or one or more drugs, or a combination of alcohol and one or more drugs, that affects the person to a degree that the person is substantially incapable, either mentally or physically, or both mentally and physically, to exercise clear judgment, sufficient physical control, or due care in the safe operation of a vehicle.
(g) “Driving while ability impaired” means driving a motor vehicle or vehicle when a person has consumed alcohol or one or more drugs, or a combination of both alcohol and one or more drugs, that affects the person to the slightest degree so that the person is less able than the person ordinarily would have been, either mentally or physically, or both mentally and physically, to exercise clear judgment, sufficient physical control, or due care in the safe operation of a vehicle.
(h) Pursuant to section 16-2-106, C.R.S., in charging the offense of DUI, it shall be sufficient to describe the offense charged as “drove a vehicle under the influence of alcohol or drugs or both”.
(i) Pursuant to section 16-2-106, C.R.S., in charging the offense of DWAI, it shall be sufficient to describe the offense charged as “drove a vehicle while impaired by alcohol or drugs or both”.
(j) For the purposes of this section, a person is deemed to have a prior conviction for DUI, DUI per se, or DWAI; vehicular homicide, as described in section 18-3-106(1)(b), C.R.S.; or vehicular assault, as described in section 18-3-205(1)(b), C.R.S., if the person has been convicted under the laws of this state or under the laws of any other state, the United States, or any territory subject to the jurisdiction of the United States, of an act that, if committed within this state, would constitute any of these offenses. The prosecution shall set forth such prior convictions in the indictment or information.
(k)(I) If a defendant is convicted of a class 4 felony pursuant to this section, the court shall sentence the person in accordance with the provisions of section 18-1.3-401, C.R.S.
(II)(A) Notwithstanding the provisions of subparagraph (I) of this paragraph (k), before the imposition of any sentence to the department of corrections for a felony DUI, DUI per se, or DWAI offense, at sentencing or at resentencing after a revocation of probation or a community corrections sentence, the court shall consider all the factors described in sub-subparagraph (B) of this subparagraph (II).
(B) If the court sentences the defendant to the department of corrections for a felony DUI, DUI per se, or DWAI offense, it must determine that incarceration is the most suitable option given the facts and circumstances of the case, including the defendant’s willingness to participate in treatment. Additionally, the court shall consider whether all other reasonable and appropriate sanctions and responses to the violation that are available to the court have been exhausted, do not appear likely to be successful if tried, or present an unacceptable risk to public safety.
(2)(a) A person who drives a motor vehicle or vehicle when the person’s BAC is 0.08 or more at the time of driving or within two hours after driving commits DUI per se. During a trial, if the state’s evidence raises the issue, or if a defendant presents some credible evidence, that the defendant consumed alcohol between the time that the defendant stopped driving and the time that testing occurred, such issue shall be an affirmative defense, and the prosecution must establish beyond a reasonable doubt that the minimum 0.08 blood or breath alcohol content required in this paragraph (a) was reached as a result of alcohol consumed by the defendant before the defendant stopped driving. DUI per se is a misdemeanor, but it is a class 4 felony if the violation occurred after three or more prior convictions, arising out of separate and distinct criminal episodes, for DUI, DUI per se, or DWAI; vehicular homicide, as described in section 18-3-106(1)(b), C.R.S.; vehicular assault, as described in section 18-3-205(1)(b), C.R.S.; or any combination thereof.
(a.5) Repealed by Laws 2015, Ch. 262, § 1, eff. Aug. 5, 2015.
(b) In any prosecution for the offense of DUI per se, the defendant shall be entitled to offer direct and circumstantial evidence to show that there is a disparity between what any tests show and other facts so that the trier of fact could infer that the tests were in some way defective or inaccurate. Such evidence may include testimony of nonexpert witnesses relating to the absence of any or all of the common symptoms or signs of intoxication for the purpose of impeachment of the accuracy of the analysis of the person’s blood or breath.
(c) Pursuant to section 16-2-106, C.R.S., in charging the offense of DUI per se, it shall be sufficient to describe the offense charged as “drove a vehicle with excessive alcohol content”.
(d)(I) It is a class A traffic infraction for any person under twenty-one years of age to drive a motor vehicle or vehicle when the person’s BAC, as shown by analysis of the person’s breath, is at least 0.02 but not more than 0.05 at the time of driving or within two hours after driving. The court, upon sentencing a defendant pursuant to this subparagraph (I), may order, in addition to any penalty imposed under a class A traffic infraction, that the defendant perform up to twenty-four hours of useful public service, subject to the conditions and restrictions of section 18-1.3-507, C.R.S., and may further order that the defendant submit to and complete an alcohol evaluation or assessment, an alcohol education program, or an alcohol treatment program at such defendant’s own expense.
(II) A second or subsequent violation of this paragraph (d) is a class 2 traffic misdemeanor.
(3) The offenses described in subsections (1) and (2) of this section are strict liability offenses.
(4) No court shall accept a plea of guilty to a non-alcohol-related or non-drug-related traffic offense or guilty to the offense of UDD from a person charged with DUI or DUI per se; except that the court may accept a plea of guilty to a non-alcohol-related or non-drug-related traffic offense or to UDD upon a good faith representation by the prosecuting attorney that the attorney could not establish a prima facie case if the defendant were brought to trial on the original alcohol-related or drug-related offense.
(5) Notwithstanding the provisions of section 18-1-408, C.R.S., during a trial of any person accused of both DUI and DUI per se, the court shall not require the prosecution to elect between the two violations. The court or a jury may consider and convict the person of either DUI or DWAI, or DUI per se, or both DUI and DUI per se, or both DWAI and DUI per se. If the person is convicted of more than one violation, the sentences imposed shall run concurrently.
(6)(a) In any prosecution for DUI or DWAI, the defendant’s BAC or drug content at the time of the commission of the alleged offense or within a reasonable time thereafter gives rise to the following presumptions or inferences:
(I) If at such time the defendant’s BAC was 0.05 or less, it shall be presumed that the defendant was not under the influence of alcohol and that the defendant’s ability to operate a motor vehicle or vehicle was not impaired by the consumption of alcohol.
(II) If at such time the defendant’s BAC was in excess of 0.05 but less than 0.08, such fact gives rise to the permissible
inference that the defendant’s ability to operate a motor vehicle or vehicle was impaired by the consumption of alcohol, and such fact may also be considered with other competent evidence in determining whether or not the defendant was under the influence of alcohol.
(III) If at such time the defendant’s BAC was 0.08 or more, such fact gives rise to the permissible inference that the defendant was under the influence of alcohol.
(IV) If at such time the driver’s blood contained five nanograms or more of delta 9-tetrahydrocannabinol per milliliter in whole blood, as shown by analysis of the defendant’s blood, such fact gives rise to a permissible inference that the defendant was under the influence of one or more drugs.
(b) The limitations of this subsection (6) shall not be construed as limiting the introduction, reception, or consideration of any other competent evidence bearing upon the question of whether or not the defendant was under the influence of alcohol or whether or not the defendant’s ability to operate a motor vehicle or vehicle was impaired by the consumption of alcohol.
(c) In all actions, suits, and judicial proceedings in any court of this state concerning alcohol-related or drug-related traffic offenses, the court shall take judicial notice of methods of testing a person’s alcohol or drug level and of the design and operation of devices, as certified by the department of public health and environment, for testing a person’s blood, breath, saliva, or urine to determine such person’s alcohol or drug level. The department of public health and environment may, by rule, determine that, because of the reliability of the results from certain devices, the collection or preservation of a second sample of a person’s blood, saliva, or urine or the collection and preservation of a delayed breath alcohol specimen is not required. This paragraph (c) shall not prevent the necessity of establishing during a trial that the testing devices used were working properly and that such testing devices were properly operated. Nothing in this paragraph (c) shall preclude a defendant from offering evidence concerning the accuracy of testing devices.
(d) If a person refuses to take or to complete, or to cooperate with the completing of, any test or tests as provided in section 42-4-1301.1 and such person subsequently stands trial for DUI or DWAI, the refusal to take or to complete, or to cooperate with the completing of, any test or tests shall be admissible into evidence at the trial, and a person may not claim the privilege against self-incrimination with regard to admission of refusal to take or to complete, or to cooperate with the completing of, any test or tests.
(e) Involuntary blood test--admissibility. Evidence acquired through an involuntary blood test pursuant to section 42-4-1301.1(3) shall be admissible in any prosecution for DUI, DUI per se, DWAI, or UDD, and in any prosecution for criminally negligent homicide pursuant to section 18-3-105, C.R.S., vehicular homicide pursuant to section 18-3-106(1)(b), C.R.S., assault in the third degree pursuant to section 18-3-204, C.R.S., or vehicular assault pursuant to section 18-3-205(1)(b), C.R.S.
(f) Chemical test -- admissibility. Strict compliance with the rules and regulations prescribed by the department of public health and environment shall not be a prerequisite to the admissibility of test results at trial unless the court finds that the extent of noncompliance with a board of health rule has so impaired the validity and reliability of the testing method and the test results as to render the evidence inadmissible. In all other circumstances, failure to strictly comply with such rules and regulations shall only be considered in the weight to be given to the test results and not to the admissibility of such test results.
(g) It shall not be a prerequisite to the admissibility of test results at trial that the prosecution present testimony concerning the composition of any kit used to obtain blood, urine, saliva, or breath specimens. A sufficient evidentiary foundation concerning the compliance of such kits with the rules and regulations of the department of public health and environment shall be established by the introduction of a copy of the manufacturer’s or supplier’s certificate of compliance with such rules and regulations if such certificate specifies the contents, sterility, chemical makeup, and amounts of chemicals contained in such kit.
(h) In any trial for a violation of this section, the testimony of a law enforcement officer that he or she witnessed the taking of a blood specimen by a person who the law enforcement officer reasonably believed was authorized to withdraw blood specimens shall be sufficient evidence that such person was so authorized, and testimony from the person who obtained the blood specimens concerning such person’s authorization to obtain blood specimens shall not be a prerequisite to the admissibility of test results concerning the blood specimens obtained.
(i)(I) Following the lawful contact with a person who has been driving a motor vehicle or vehicle and when a law enforcement officer reasonably suspects that a person was driving a motor vehicle or vehicle while under the influence of or while impaired by alcohol, the law enforcement officer may conduct a preliminary screening test using a device approved by the executive director of the department of public health and environment after first advising the driver that the driver may either refuse or agree to provide a sample of the driver’s breath for such preliminary test; except that, if the driver is under twenty-one years of age, the law enforcement officer may, after providing such advisement to the person, conduct such preliminary screening test if the officer reasonably suspects that the person has consumed any alcohol.
(II) The results of this preliminary screening test may be used by a law enforcement officer in determining whether probable cause exists to believe such person was driving a motor vehicle or vehicle in violation of this section and whether to administer a test pursuant to section 42-4-1301.1(2).
(III) Neither the results of such preliminary screening test nor the fact that the person refused such test shall be used in any court action except in a hearing outside of the presence of a jury, when such hearing is held to determine if a law enforcement officer had probable cause to believe that the driver committed a violation of this section. The results of such preliminary screening test shall be made available to the driver or the driver’s attorney on request.
(j) In any trial for a violation of this section, if, at the time of the alleged offense, the person possessed a valid medical marijuana registry identification card, as defined in section 25-1.5-106(2)(e), C.R.S., issued to himself or herself, the prosecution shall not use such fact as part of the prosecution’s case in chief.
(k) In any traffic stop, the driver’s possession of a valid medical marijuana registry identification card, as defined in section 25-1.5-106(2)(e), C.R.S., issued to himself or herself shall not, in the absence of other contributing factors, constitute probable cause for a peace officer to require the driver to submit to an analysis of his or her blood.
(7) Repealed by Laws 2010, Ch. 258, § 1, eff. July 1, 2010.
(8) A second or subsequent violation of this section committed by a person under eighteen years of age may be filed in juvenile court.

§ 42-4-1301.1. Expressed consent for the taking of blood, breath, urine, or saliva sample--testing--fund--rules--repeal
Effective: August 6, 2014
(1) Any person who drives any motor vehicle upon the streets and highways and elsewhere throughout this state shall be deemed to have expressed such person’s consent to the provisions of this section.
(2)(a)(I) A person who drives a motor vehicle upon the streets and highways and elsewhere throughout this state shall be required to take and complete, and to cooperate in the taking and completing of, any test or tests of the person’s breath or blood for the purpose of determining the alcoholic content of the person’s blood or breath when so requested and directed by a law enforcement officer having probable cause to believe that the person was driving a motor vehicle in violation of the prohibitions against DUI, DUI per se, DWAI, or UDD. Except as otherwise provided in this section, if a person who is twenty-one years of age or older requests that the test be a blood test, then the test shall be of his or her blood; but, if the person requests that a specimen of his or her blood not be drawn, then a specimen of the person’s breath shall be obtained and tested. A person who is under twenty-one years of age shall be entitled to request a blood test unless the alleged violation is UDD, in which case a specimen of the person’s breath shall be obtained and tested, except as provided in subparagraph (II) of this paragraph (a).
(II) Except as otherwise provided in paragraph (a.5) of this subsection (2), if a person elects either a blood test or a breath test, the person shall not be permitted to change the election, and, if the person fails to take and complete, and to cooperate in the completing of, the test elected, the failure shall be deemed to be a refusal to submit to testing. If the person is unable to take, or to complete, or to cooperate in the completing of a breath test because of injuries, illness, disease, physical infirmity, or physical incapacity, or if the person is receiving medical treatment at a location at which a breath testing instrument certified by the department of public health and environment is not available, the test shall be of the person’s blood.
(III) If a law enforcement officer requests a test under this paragraph (a), the person must cooperate with the request such that the sample of blood or breath can be obtained within two hours of the person’s driving.
(a.5)(I) If a law enforcement officer who requests a person to take a breath or blood test under paragraph (a) of this subsection (2) determines there are extraordinary circumstances that prevent the completion of the test elected by the person within the two-hour time period required by subparagraph (III) of paragraph (a) of this subsection (2), the officer shall inform the person of the extraordinary circumstances and request and direct the person to take and complete the other test described in paragraph (a) of this subsection (2). The person shall then be required to take and complete, and to cooperate in the completing of, the other test.
(II) A person who initially requests and elects to take a blood or breath test, but who is requested and directed by the law enforcement officer to take the other test because of the extraordinary circumstances described in subparagraph (I) of this paragraph (a.5), may change his or her election for the purpose of complying with the officer’s request. The change in the election of which test to take shall not be deemed to be a refusal to submit to testing.
(III) If the person fails to take and complete, and to cooperate in the completing of, the other test requested by the law enforcement officer pursuant to subparagraph (I) of this paragraph (a.5), the failure shall be deemed to be a refusal to submit to testing.
(IV)(A) As used in this paragraph (a.5), “extraordinary circumstances” means circumstances beyond the control of, and not created by, the law enforcement officer who requests and directs a person to take a blood or breath test in accordance with this subsection (2) or the law enforcement authority with whom the officer is employed.
(B) “Extraordinary circumstances” includes, but shall not be limited to, weather-related delays, high call volume affecting medical personnel, power outages, malfunctioning breath test equipment, and other circumstances that preclude the timely collection and testing of a blood or breath sample by a qualified person in accordance with law.
(C) “Extraordinary circumstances” does not include inconvenience, a busy workload on the part of the law enforcement officer or law enforcement authority, minor delay that does not compromise the two-hour test period specified in subparagraph (III) of paragraph (a) of this subsection (2), or routine circumstances that are subject to the control of the law enforcement officer or law enforcement authority.
(b)(I) Any person who drives any motor vehicle upon the streets and highways and elsewhere throughout this state shall be required to submit to and to complete, and to cooperate in the completing of, a test or tests of such person’s blood, saliva, and urine for the purpose of determining the drug content within the person’s system when so requested and directed by a law enforcement officer having probable cause to believe that the person was driving a motor vehicle in violation of the prohibitions against DUI or DWAI and when it is reasonable to require such testing of blood, saliva, and urine to determine whether such person was under the influence of, or impaired by, one or more drugs, or one or more controlled substances, or a combination of both alcohol and one or more drugs, or a combination of both alcohol and one or more controlled substances.
(II) If a law enforcement officer requests a test under this paragraph (b), the person must cooperate with the request such that the sample of blood, saliva, or urine can be obtained within two hours of the person’s driving.
(3) Any person who is required to take and to complete, and to cooperate in the completing of, any test or tests shall cooperate with the person authorized to obtain specimens of such person’s blood, breath, saliva, or urine, including the signing of any release or consent forms required by any person, hospital, clinic, or association authorized to obtain such specimens. If such person does not cooperate with the person, hospital, clinic, or association authorized to obtain such specimens, including the signing of any release or consent forms, such noncooperation shall be considered a refusal to submit to testing. No law enforcement officer shall physically restrain any person for the purpose of obtaining a specimen of such person’s blood, breath, saliva, or urine for testing except when the officer has probable cause to believe that the person has committed criminally negligent homicide pursuant to section 18-3-105, C.R.S., vehicular homicide pursuant to section 18-3-106(1)(b), C.R.S., assault in the third degree pursuant to section 18-3-204, C.R.S., or vehicular assault pursuant to section 18-3-205(1)(b), C.R.S., and the person is refusing to take or to complete, or to cooperate in the completing of, any test or tests, then, in such event, the law enforcement officer may require a blood test.
(4) Any driver of a commercial motor vehicle requested to submit to a test as provided in paragraph (a) or (b) of subsection (2) of this section shall be warned by the law enforcement officer requesting the test that a refusal to submit to the test shall result in an out-of-service order as defined under section 42-2-402(8) for a period of twenty-four hours and a revocation of the privilege to operate a commercial motor vehicle for one year as provided under section 42-2-126.
(5) The tests shall be administered at the direction of a law enforcement officer having probable cause to believe that the person had been driving a motor vehicle in violation of section 42-4-1301 and in accordance with rules and regulations prescribed by the department of public health and environment concerning the health of the person being tested and the accuracy of such testing.
(6)(a) No person except a physician, a registered nurse, a paramedic, as certified in part 2 of article 3.5 of title 25, C.R.S., an emergency medical service provider, as defined in part 1 of article 3.5 of title 25, C.R.S., or a person whose normal duties include withdrawing blood samples under the supervision of a physician or registered nurse shall withdraw blood to determine the alcoholic or drug content of the blood for purposes of this section.
(b) No civil liability shall attach to any person authorized to obtain blood, breath, saliva, or urine specimens or to any hospital, clinic, or association in or for which such specimens are obtained as provided in this section as a result of the act of obtaining such specimens from any person submitting thereto if such specimens were obtained according to the rules and regulations prescribed by the department of public health and environment; except that this provision shall not relieve any such person from liability for negligence in the obtaining of any specimen sample.
(7) A preliminary screening test conducted by a law enforcement officer pursuant to section 42-4-1301(6)(i) shall not substitute for or qualify as the test or tests required by subsection (2) of this section.
(8) Any person who is dead or unconscious shall be tested to determine the alcohol or drug content of the person’s blood or any drug content within such person’s system as provided in this section. If a test cannot be administered to a person who is unconscious, hospitalized, or undergoing medical treatment because the test would endanger the person’s life or health, the law enforcement agency shall be allowed to test any blood, urine, or saliva that was obtained and not utilized by a health care provider and shall have access to that portion of the analysis and results of any tests administered by such provider that shows the alcohol or drug content of the person’s blood, urine, or saliva or any drug content within the person’s system. Such test results shall not be considered privileged communications, and the provisions of section 13-90-107, C.R.S., relating to the physician-patient privilege shall not apply. Any person who is dead, in addition to the tests prescribed, shall also have the person’s blood checked for carbon monoxide content and for the presence of drugs, as prescribed by the department of public health and environment. Such information obtained shall be made a part of the accident report.
(9)(a) There is created in the state treasury the evidential breath-testing cash fund, referred to in this section as the “fund”, for the collection of moneys to purchase breath-testing devices for law enforcement agencies. The fund includes any moneys appropriated to the fund by the general assembly and any moneys credited to the fund pursuant to paragraph (c) of this subsection (9). The moneys in the fund are subject to annual appropriation by the general assembly to the department of public health and environment created in section 25-1-102, C.R.S., for the purposes described in this subsection (9).
(b) All interest derived from the deposit and investment of moneys in the fund must remain in the fund.

(c) The department of public health and environment is authorized to accept any gifts, grants, or donations from any private or public source on behalf of the state for the purposes described in this section. The department of public health and environment shall transmit all such gifts, grants, and donations to the state treasurer, who shall credit the same to the fund.
(d) The state board of health created in section 25-1-103, C.R.S., may promulgate rules for the administration of the fund for the purposes described in this subsection (9).
(e) This subsection (9) is repealed, effective September 1, 2024. Before repeal, the department of regulatory agencies, pursuant to 24-34-104, shall review the use of the fund by the department of public health and environment for the purposes described in this subsection (9).

During a trial, if the state’s evidence raises the issue, or if a defendant presents some credible evidence, that the defendant consumed alcohol between the time that the defendant stopped driving and the time that testing occurred, such issue shall be an affirmative defense, and the prosecution must establish beyond a reasonable doubt that the minimum 0.08 blood or breath alcohol content required in this paragraph (a) was reached as a result of alcohol consumed by the defendant before the defendant stopped driving. DUI per se is a misdemeanor, but it is a class 4 felony if the violation occurred after three or more prior convictions, arising out of separate and distinct criminal episodes, for DUI, DUI per se, or DWAI; vehicular homicide, as described in section 18-3-106(1)(b), C.R.S.; vehicular assault, as described in section 18-3-205(1)(b), C.R.S.; or any combination thereof.
(a.5) Repealed by Laws 2015, Ch. 262, § 1, eff. Aug. 5, 2015.
(b) In any prosecution for the offense of DUI per se, the defendant shall be entitled to offer direct and circumstantial evidence to show that there is a disparity between what any tests show and other facts so that the trier of fact could infer that the tests were in some way defective or inaccurate. Such evidence may include testimony of nonexpert witnesses relating to the absence of any or all of the common symptoms or signs of intoxication for the purpose of impeachment of the accuracy of the analysis of the person’s blood or breath.
(c) Pursuant to section 16-2-106, C.R.S., in charging the offense of DUI per se, it shall be sufficient to describe the offense charged as “drove a vehicle with excessive alcohol content”.
(d)(I) It is a class A traffic infraction for any person under twenty-one years of age to drive a motor vehicle or vehicle when the person’s BAC, as shown by analysis of the person’s breath, is at least 0.02 but not more than 0.05 at the time of driving or within two hours after driving. The court, upon sentencing a defendant pursuant to this subparagraph (I), may order, in addition to any penalty imposed under a class A traffic infraction, that the defendant perform up to twenty-four hours of useful public service, subject to the conditions and restrictions of section 18-1.3-507, C.R.S., and may further order that the defendant submit to and complete an alcohol evaluation or assessment, an alcohol education program, or an alcohol treatment program at such defendant’s own expense.
(II) A second or subsequent violation of this paragraph (d) is a class 2 traffic misdemeanor.
(3) The offenses described in subsections (1) and (2) of this section are strict liability offenses.
(4) No court shall accept a plea of guilty to a non-alcohol-related or non-drug-related traffic offense or guilty to the offense of UDD from a person charged with DUI or DUI per se; except that the court may accept a plea of guilty to a non-alcohol-related or non-drug-related traffic offense or to UDD upon a good faith representation by the prosecuting attorney that the attorney could not establish a prima facie case if the defendant were brought to trial on the original alcohol-related or drug-related offense.
(5) Notwithstanding the provisions of section 18-1-408, C.R.S., during a trial of any person accused of both DUI and DUI per se, the court shall not require the prosecution to elect between the two violations. The court or a jury may consider and convict the person of either DUI or DWAI, or DUI per se, or both DUI and DUI per se, or both DWAI and DUI per se. If the person is convicted of more than one violation, the sentences imposed shall run concurrently.
(6)(a) In any prosecution for DUI or DWAI, the defendant’s BAC or drug content at the time of the commission of the alleged offense or within a reasonable time thereafter gives rise to the following presumptions or inferences:
(I) If at such time the defendant’s BAC was 0.05 or less, it shall be presumed that the defendant was not under the influence of alcohol and that the defendant’s ability to operate a motor vehicle or vehicle was not impaired by the consumption of alcohol.
(II) If at such time the defendant’s BAC was in excess of 0.05 but less than 0.08, such fact gives rise to the permissible
inference that the defendant’s ability to operate a motor vehicle or vehicle was impaired by the consumption of alcohol, and such fact may also be considered with other competent evidence in determining whether or not the defendant was under the influence of alcohol.
(III) If at such time the defendant’s BAC was 0.08 or more, such fact gives rise to the permissible inference that the defendant was under the influence of alcohol.
(IV) If at such time the driver’s blood contained five nanograms or more of delta 9-tetrahydrocannabinol per milliliter in whole blood, as shown by analysis of the defendant’s blood, such fact gives rise to a permissible inference that the defendant was under the influence of one or more drugs.
(b) The limitations of this subsection (6) shall not be construed as limiting the introduction, reception, or consideration of any other competent evidence bearing upon the question of whether or not the defendant was under the influence of alcohol or whether or not the defendant’s ability to operate a motor vehicle or vehicle was impaired by the consumption of alcohol.
(c) In all actions, suits, and judicial proceedings in any court of this state concerning alcohol-related or drug-related traffic offenses, the court shall take judicial notice of methods of testing a person’s alcohol or drug level and of the design and operation of devices, as certified by the department of public health and environment, for testing a person’s blood, breath, saliva, or urine to determine such person’s alcohol or drug level. The department of public health and environment may, by rule, determine that, because of the reliability of the results from certain devices, the collection or preservation of a second sample of a person’s blood, saliva, or urine or the collection and preservation of a delayed breath alcohol specimen is not required. This paragraph (c) shall not prevent the necessity of establishing during a trial that the testing devices used were working properly and that such testing devices were properly operated. Nothing in this paragraph (c) shall preclude a defendant from offering evidence concerning the accuracy of testing devices.
(d) If a person refuses to take or to complete, or to cooperate with the completing of, any test or tests as provided in section 42-4-1301.1 and such person subsequently stands trial for DUI or DWAI, the refusal to take or to complete, or to cooperate with the completing of, any test or tests shall be admissible into evidence at the trial, and a person may not claim the privilege against self-incrimination with regard to admission of refusal to take or to complete, or to cooperate with the completing of, any test or tests.
(e) Involuntary blood test--admissibility. Evidence acquired through an involuntary blood test pursuant to section 42-4-1301.1(3) shall be admissible in any prosecution for DUI, DUI per se, DWAI, or UDD, and in any prosecution for criminally negligent homicide pursuant to section 18-3-105, C.R.S., vehicular homicide pursuant to section 18-3-106(1)(b), C.R.S., assault in the third degree pursuant to section 18-3-204, C.R.S., or vehicular assault pursuant to section 18-3-205(1)(b), C.R.S.
(f) Chemical test -- admissibility. Strict compliance with the rules and regulations prescribed by the department of public health and environment shall not be a prerequisite to the admissibility of test results at trial unless the court finds that the extent of noncompliance with a board of health rule has so impaired the validity and reliability of the testing method and the test results as to render the evidence inadmissible. In all other circumstances, failure to strictly comply with such rules and regulations shall only be considered in the weight to be given to the test results and not to the admissibility of such test results.
(g) It shall not be a prerequisite to the admissibility of test results at trial that the prosecution present testimony concerning the composition of any kit used to obtain blood, urine, saliva, or breath specimens. A sufficient evidentiary foundation concerning the compliance of such kits with the rules and regulations of the department of public health and environment shall be established by the introduction of a copy of the manufacturer’s or supplier’s certificate of compliance with such rules and regulations if such certificate specifies the contents, sterility, chemical makeup, and amounts of chemicals contained in such kit.
(h) In any trial for a violation of this section, the testimony of a law enforcement officer that he or she witnessed the taking of a blood specimen by a person who the law enforcement officer reasonably believed was authorized to withdraw blood specimens shall be sufficient evidence that such person was so authorized, and testimony from the person who obtained the blood specimens concerning such person’s authorization to obtain blood specimens shall not be a prerequisite to the admissibility of test results concerning the blood specimens obtained.
(i)(I) Following the lawful contact with a person who has been driving a motor vehicle or vehicle and when a law enforcement officer reasonably suspects that a person was driving a motor vehicle or vehicle while under the influence of or while impaired by alcohol, the law enforcement officer may conduct a preliminary screening test using a device approved by the executive director of the department of public health and environment after first advising the driver that the driver may either refuse or agree to provide a sample of the driver’s breath for such preliminary test; except that, if the driver is under twenty-one years of age, the law enforcement officer may, after providing such advisement to the person, conduct such preliminary screening test if the officer reasonably suspects that the person has consumed any alcohol.
(II) The results of this preliminary screening test may be used by a law enforcement officer in determining whether probable cause exists to believe such person was driving a motor vehicle or vehicle in violation of this section and whether to administer a test pursuant to section 42-4-1301.1(2).
(III) Neither the results of such preliminary screening test nor the fact that the person refused such test shall be used in any court action except in a hearing outside of the presence of a jury, when such hearing is held to determine if a law enforcement officer had probable cause to believe that the driver committed a violation of this section. The results of such preliminary screening test shall be made available to the driver or the driver’s attorney on request.
(j) In any trial for a violation of this section, if, at the time of the alleged offense, the person possessed a valid medical marijuana registry identification card, as defined in section 25-1.5-106(2)(e), C.R.S., issued to himself or herself, the prosecution shall not use such fact as part of the prosecution’s case in chief.
(k) In any traffic stop, the driver’s possession of a valid medical marijuana registry identification card, as defined in section 25-1.5-106(2)(e), C.R.S., issued to himself or herself shall not, in the absence of other contributing factors, constitute probable cause for a peace officer to require the driver to submit to an analysis of his or her blood.
(7) Repealed by Laws 2010, Ch. 258, § 1, eff. July 1, 2010.
(8) A second or subsequent violation of this section committed by a person under eighteen years of age may be filed in juvenile court.
C.R.S.A. § 42-4-1301.1
§ 42-4-1301.1. Expressed consent for the taking of blood, breath, urine, or saliva sample--testing--fund--rules--repeal
Effective: August 6, 2014
(1) Any person who drives any motor vehicle upon the streets and highways and elsewhere throughout this state shall be deemed to have expressed such person’s consent to the provisions of this section.
(2)(a)(I) A person who drives a motor vehicle upon the streets and highways and elsewhere throughout this state shall be required to take and complete, and to cooperate in the taking and completing of, any test or tests of the person’s breath or blood for the purpose of determining the alcoholic content of the person’s blood or breath when so requested and directed by a law enforcement officer having probable cause to believe that the person was driving a motor vehicle in violation of the prohibitions against DUI, DUI per se, DWAI, or UDD. Except as otherwise provided in this section, if a person who is twenty-one years of age or older requests that the test be a blood test, then the test shall be of his or her blood; but, if the person requests that a specimen of his or her blood not be drawn, then a specimen of the person’s breath shall be obtained and tested. A person who is under twenty-one years of age shall be entitled to request a blood test unless the alleged violation is UDD, in which case a specimen of the person’s breath shall be obtained and tested, except as provided in subparagraph (II) of this paragraph (a).
(II) Except as otherwise provided in paragraph (a.5) of this subsection (2), if a person elects either a blood test or a breath test, the person shall not be permitted to change the election, and, if the person fails to take and complete, and to cooperate in the completing of, the test elected, the failure shall be deemed to be a refusal to submit to testing. If the person is unable to take, or to complete, or to cooperate in the completing of a breath test because of injuries, illness, disease, physical infirmity, or physical incapacity, or if the person is receiving medical treatment at a location at which a breath testing instrument certified by the department of public health and environment is not available, the test shall be of the person’s blood.
(III) If a law enforcement officer requests a test under this paragraph (a), the person must cooperate with the request such that the sample of blood or breath can be obtained within two hours of the person’s driving.
(a.5)(I) If a law enforcement officer who requests a person to take a breath or blood test under paragraph (a) of this subsection (2) determines there are extraordinary circumstances that prevent the completion of the test elected by the person within the two-hour time period required by subparagraph (III) of paragraph (a) of this subsection (2), the officer shall inform the person of the extraordinary circumstances and request and direct the person to take and complete the other test described in paragraph (a) of this subsection (2). The person shall then be required to take and complete, and to cooperate in the completing of, the other test.
(II) A person who initially requests and elects to take a blood or breath test, but who is requested and directed by the law enforcement officer to take the other test because of the extraordinary circumstances described in subparagraph (I) of this paragraph (a.5), may change his or her election for the purpose of complying with the officer’s request. The change in the election of which test to take shall not be deemed to be a refusal to submit to testing.
(III) If the person fails to take and complete, and to cooperate in the completing of, the other test requested by the law enforcement officer pursuant to subparagraph (I) of this paragraph (a.5), the failure shall be deemed to be a refusal to submit to testing.
(IV)(A) As used in this paragraph (a.5), “extraordinary circumstances” means circumstances beyond the control of, and not created by, the law enforcement officer who requests and directs a person to take a blood or breath test in accordance with this subsection (2) or the law enforcement authority with whom the officer is employed.
(B) “Extraordinary circumstances” includes, but shall not be limited to, weather-related delays, high call volume affecting medical personnel, power outages, malfunctioning breath test equipment, and other circumstances that preclude the timely collection and testing of a blood or breath sample by a qualified person in accordance with law.
(C) “Extraordinary circumstances” does not include inconvenience, a busy workload on the part of the law enforcement officer or law enforcement authority, minor delay that does not compromise the two-hour test period specified in subparagraph (III) of paragraph (a) of this subsection (2), or routine circumstances that are subject to the control of the law enforcement officer or law enforcement authority.
(b)(I) Any person who drives any motor vehicle upon the streets and highways and elsewhere throughout this state shall be required to submit to and to complete, and to cooperate in the completing of, a test or tests of such person’s blood, saliva, and urine for the purpose of determining the drug content within the person’s system when so requested and directed by a law enforcement officer having probable cause to believe that the person was driving a motor vehicle in violation of the prohibitions against DUI or DWAI and when it is reasonable to require such testing of blood, saliva, and urine to determine whether such person was under the influence of, or impaired by, one or more drugs, or one or more controlled substances, or a combination of both alcohol and one or more drugs, or a combination of both alcohol and one or more controlled substances.
(II) If a law enforcement officer requests a test under this paragraph (b), the person must cooperate with the request such that the sample of blood, saliva, or urine can be obtained within two hours of the person’s driving.
(3) Any person who is required to take and to complete, and to cooperate in the completing of, any test or tests shall cooperate with the person authorized to obtain specimens of such person’s blood, breath, saliva, or urine, including the signing of any release or consent forms required by any person, hospital, clinic, or association authorized to obtain such specimens. If such person does not cooperate with the person, hospital, clinic, or association authorized to obtain such specimens, including the signing of any release or consent forms, such noncooperation shall be considered a refusal to submit to testing. No law enforcement officer shall physically restrain any person for the purpose of obtaining a specimen of such person’s blood, breath, saliva, or urine for testing except when the officer has probable cause to believe that the person has committed criminally negligent homicide pursuant to section 18-3-105, C.R.S., vehicular homicide pursuant to section 18-3-106(1)(b), C.R.S., assault in the third degree pursuant to section 18-3-204, C.R.S., or vehicular assault pursuant to section 18-3-205(1)(b), C.R.S., and the person is refusing to take or to complete, or to cooperate in the completing of, any test or tests, then, in such event, the law enforcement officer may require a blood test.
(4) Any driver of a commercial motor vehicle requested to submit to a test as provided in paragraph (a) or (b) of subsection (2) of this section shall be warned by the law enforcement officer requesting the test that a refusal to submit to the test shall result in an out-of-service order as defined under section 42-2-402(8) for a period of twenty-four hours and a revocation of the privilege to operate a commercial motor vehicle for one year as provided under section 42-2-126.
(5) The tests shall be administered at the direction of a law enforcement officer having probable cause to believe that the person had been driving a motor vehicle in violation of section 42-4-1301 and in accordance with rules and regulations prescribed by the department of public health and environment concerning the health of the person being tested and the accuracy of such testing.
(6)(a) No person except a physician, a registered nurse, a paramedic, as certified in part 2 of article 3.5 of title 25, C.R.S., an emergency medical service provider, as defined in part 1 of article 3.5 of title 25, C.R.S., or a person whose normal duties include withdrawing blood samples under the supervision of a physician or registered nurse shall withdraw blood to determine the alcoholic or drug content of the blood for purposes of this section.
(b) No civil liability shall attach to any person authorized to obtain blood, breath, saliva, or urine specimens or to any hospital, clinic, or association in or for which such specimens are obtained as provided in this section as a result of the act of obtaining such specimens from any person submitting thereto if such specimens were obtained according to the rules and regulations prescribed by the department of public health and environment; except that this provision shall not relieve any such person from liability for negligence in the obtaining of any specimen sample.
(7) A preliminary screening test conducted by a law enforcement officer pursuant to section 42-4-1301(6)(i) shall not substitute for or qualify as the test or tests required by subsection (2) of this section.
(8) Any person who is dead or unconscious shall be tested to determine the alcohol or drug content of the person’s blood or any drug content within such person’s system as provided in this section. If a test cannot be administered to a person who is unconscious, hospitalized, or undergoing medical treatment because the test would endanger the person’s life or health, the law enforcement agency shall be allowed to test any blood, urine, or saliva that was obtained and not utilized by a health care provider and shall have access to that portion of the analysis and results of any tests administered by such provider that shows the alcohol or drug content of the person’s blood, urine, or saliva or any drug content within the person’s system. Such test results shall not be considered privileged communications, and the provisions of section 13-90-107, C.R.S., relating to the physician-patient privilege shall not apply. Any person who is dead, in addition to the tests prescribed, shall also have the person’s blood checked for carbon monoxide content and for the presence of drugs, as prescribed by the department of public health and environment. Such information obtained shall be made a part of the accident report.
(9)(a) There is created in the state treasury the evidential breath-testing cash fund, referred to in this section as the “fund”, for the collection of moneys to purchase breath-testing devices for law enforcement agencies. The fund includes any moneys appropriated to the fund by the general assembly and any moneys credited to the fund pursuant to paragraph (c) of this subsection (9). The moneys in the fund are subject to annual appropriation by the general assembly to the department of public health and environment created in section 25-1-102, C.R.S., for the purposes described in this subsection (9).
(b) All interest derived from the deposit and investment of moneys in the fund must remain in the fund. Any unexpended or unencumbered moneys remaining in the fund at the end of a fiscal year must remain in the fund and not be transferred or credited to the general fund or another fund; except that any such unexpended and unencumbered moneys in excess of two million dollars must be credited to the general fund.
(c) The department of public health and environment is authorized to accept any gifts, grants, or donations from any private or public source on behalf of the state for the purposes described in this section. The department of public health and environment shall transmit all such gifts, grants, and donations to the state treasurer, who shall credit the same to the fund.
(d) The state board of health created in section 25-1-103, C.R.S., may promulgate rules for the administration of the fund for the purposes described in this subsection (9).
(e) This subsection (9) is repealed, effective September 1, 2024. Before repeal, the department of regulatory agencies, pursuant to 24-34-104, shall review the use of the fund by the department of public health and environment for the purposes described in this subsection (9).
