DUI/DWAI/DUID Defense: What We Do For You

We have successfully handled over a thousand of these cases. Enforcement is strict and the penalties are harsh but we make sure you are treated fairly.

Colorado law prohibits a person from driving a vehicle while under the influence of alcohol or drugs or while the person’s ability to drive is impaired by alcohol or drugs. These offenses are often abbreviated as DUI and DWAI, respectively. Driving while under the influence of drugs is abbreviated as DUID.

Driving Under the Influence (DUI) 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 affects the person to a degree that he or she is substantially incapable, mentally or physically, to exercise clear judgment, sufficient physical control, or due care in the safe operation of a vehicle.

Driving While Ability Impaired (DWAI) is similar, except that the person is affected to the slightest degree so that the person is less able than he or she ordinarily would have been to exercise clear judgment, etc.

There are both criminal penalties (fines, imprisonment, and required public service) and administrative penalties for drunk driving. Courts impose criminal penalties, while the Colorado Department of Revenue (the Department) imposes the administrative penalties.  Administrative penalties include the suspension or revocation of a license due to the commission of certain offenses or the accumulation of sufficient points assessed for violations.

Still other consequences may follow. If alcohol or drugs are involved in an accident causing injury or death, the penalties for vehicular assault or vehicular homicide are more stringent.  Persons convicted of a third DUI or DWAI offense within 7 years also face a mandatory 5-year license revocation under the “habitual traffic offender” statute.

Driving Laws and Marijuana

DUID: Marijuana + Driving

Colorado is one of only four states where marijuana is legal. However, similar to alcohol, it is not legal to drive any vehicle while impaired by THC.

  • The differences between alcohol DWAI and marijuana DWAI are in the testing for either substance.
  • With marijuana, the test is for blood level of active Tetrahydrocannabinol (THC).
