Alcohol and Impaired Driving

Every day, Colorado drivers are putting lives at risk by driving impaired. Each year, more than 26,000 people are arrested for DUI, and more than one-third of all Colorado traffic fatalities are alcohol-related.


With the goal of reducing the number of DUI-related fatalities and offenses in Colorado, CDOT has teamed with BACtrack to promote responsible drinking habits and the use of personal breathalyzers. BACtrack aims to help people monitor their blood alcohol content (BAC) to make informed and responsible decisions when it comes to driving.

The legal BAC limits for driving in Colorado include 0.05 for driving while ability impaired (DWAI) and 0.08 for driving under the influence (DUI). We aim to help Coloradans understand these limits, and the consequences of driving while impaired by alcohol.

Most Coloradans (73 percent) report feeling comfortable driving after having one or two drinks in a two-hour period*. While this is the social norm, alcohol affects everyone differently, and your BAC can be affected by a variety of factors—such as how much you've had to eat, how much you weigh, gender and your individual physiology.

In summer 2016, CDOT distributed smartphone breathalyzers to 225 randomly-chosen participants in the Denver metro area. In exchange, participants agreed to provide feedback to CDOT on their experience.

According to CDOT research, young adults do not consider driving after just a few drinks to be impaired driving. It's time to start knowing how alcohol affects you before making decisions that can change your life and those around you. CDOT developed a “A Few Can Still Be Dangerous” campaign to reinforce the common misconception that driving after just a few drinks isn't impaired driving. To further break that notion and continue to enlighten people to the individual effects of alcohol, CDOT is working to get breathalyzers into the hands of more Colorado residents.

The Heat Is On is Colorado's high-visibility enforcement campaign that combines increased DUI enforcement with a strong public awareness campaign during 12 enforcement periods throughout the year. CDOT provides grants to law enforcement agencies statewide to conduct overtime DUI enforcement using state and federal funding. CDOT's Public Relations Office uses federal funds for media relations, advertising and community outreach.

CDOT's Office of Transportation Safety also provides federal grants for other impaired driving programs, including DUI courts, a traffic safety resource prosecutor and law enforcement coordinator, as well as training for law enforcement in the areas of drug evaluation and standard field sobriety testing.
