Drugged Driving

Too many Coloradans admit they drive high on marijuana. And CDOT needs everyone's help to address this problem.

Join the conversation, Colorado! CDOT wants to listen and learn from you as part of a new drugged driving initiative called The Cannabis Conversation. Tell us about your habits, behaviors, opinions and thoughts about marijuana and driving. Everyone is invited to join the conversation—whether or not you consume cannabis. The only requirement is that you provide open and honest feedback.

Take our Survey

Soon, we'll be launching a 10- to 15-minute anonymous survey, which will be available here, where you can share your feedback.

Once you've taken it, pass it along! Help us gather as much feedback as possible by sharing this link with your family, friends, co-workers and social networks so they can join the conversation, too.

In-Person Engagement Opportunities

CDOT will also be taking this survey to the streets. Follow us on Facebook to find events and venues where you can talk to a CDOT representative about this campaign.

Why We're Doing This

Colorado continues to see marijuana-involved traffic crashes that result in serious consequences. It's a problem that CDOT is now seeking the community's input to help address by sparking a meaningful conversation among all Coloradans. Through this conversation, CDOT is setting out to:

  • Learn why some people drive under the influence of marijuana;
  • Learn what the public perceives as the dangers of driving while marijuana impaired;
  • Learn what would convince people not to drive high; and
  • Understand the norms and opinions around driving high from multiple perspectives.
This is a statewide, multi-year initiative that involves not just the public and marijuana users, but also industry influencers, law enforcement, local government, and other stakeholders to make sure we're seeing all angles and perspectives of the issue.

The goal? To collectively identify practical solutions that will ultimately make Colorado's roads safer.

A Few Facts

For years, CDOT and its partners have worked to educate the public about the dangers of driving high and provide marijuana users with information on how to stay safe, such as planning for a safe, sober ride.

Although past campaigns have greatly increased knowledge about the legal consequences of driving high, Colorado still has a long way to go to reach our goal of zero deaths on Colorado roads.

Check back for statistics about marijuana-impaired driving crashes, marijuana-related DUIs and DUIDs, and much more.


  • One-third of fatalities involved an impaired driver. That’s 196 fatalities.
  • More than 17 percent of all DUI arrests from the Colorado State Patrol in 2016 involved marijuana.
  • According to a 2016 survey conducted by CDOT, 55 percent of marijuana users said they believed it was safe to drive under the influence of marijuana.

Regardless of the impairing substance, the skills needed to drive safely are negatively impacted by many drugs, including cannabis. Marijuana can impair reaction time, judgment, motor skills and perception of time and distance.

Colorado law enforcement officers are trained in the detection of impairment of alcohol and drugs, and many are specially trained drug recognition experts (DRE). These officers have the ability to detect physical signs of drug impairment. DREs are viewed as one of the most effective law enforcement tools in efforts to reduce drugged driving. From 2012 to 2014, there was a 68 percent increase in the number of drug recognition experts trained in Colorado.

Colorado is a leader in the nation for public transportation. If you can’t find someone to designate as a sober driver, there are many other ways to get around.
