Alcohol and Impaired Driving

Too many 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.

Breathalyzer Program
CDOT is implementing a first-of-its-kind breathalyzer initiative for individuals who have received a first DUI conviction. We are aiming to educate individuals with a first DUI offense in order to prevent a second conviction. If you or someone you know has received a DUI recently, learn more about the program at the link below. According to Colorado DUI offense filings, 40-percent of DUI cases involve individuals with a prior DUI conviction.


  • CDOT wants to evaluate if breathalyzers can help those who’ve already been convicted of a DUI avoid a second offense and help keep Colorado roads safe.


  • We’re looking for individuals with one prior DUI willing to participate in the program to determine if breathalyzers promote responsible consumption and sober driving.


  • You will be given a smartphone breathalyzer to empower you to make responsible decisions while consuming alcohol. In return, you agree to complete surveys about your breathalyzer experience.


  • We’ll send the breathalyzer directly to you and you’ll be asked to complete online surveys.


  • Beginning immediately, participants will be asked to use their breathalyzers and complete surveys through the end of summer 2017.

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.
