DUI
42-4-1301. Driving Under the Influence - Driving with Excessive Alcoholic Content - Definitions.
(1) (a) It is a misdemeanor for any person who is under the influence of alcohol or one or more drugs, or a combination of both alcohol and one or more drugs, to drive any vehicle in this state.
(f) "Driving under the influence" means driving a vehicle when a person has consumed alcohol or one or more drugs, or a combination of alcohol and one or more drugs, which alcohol alone, or one or more drugs alone, or alcohol combined with one or more drugs 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.
(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".
(2) (a) It is a misdemeanor for any person to drive any vehicle in this state when the person's BAC is 0.08 or more at the time of driving or within two hours after driving. 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.
(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 the 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 non-expert 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".
(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, DUI per se, or habitual user; 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 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 vehicle was not impaired by the consumption 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.
(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 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.
