320 Movement

Joint Car

In response to the legalization of recreational marijuana in Colorado, CDOT launched Drive High, Get a DUI—a public outreach and education campaign to raise awareness about the dangers and laws surrounding driving while under the influence of cannabis.

People continue to die on Colorado roads due to impaired driving, and CDOT hopes this campaign will communicate three main ideas to cannabis consumers and the general public: driving high is illegal, driving high is dangerous, and plan ahead to find a sober ride.

Campaign materials available here to view and download.

Driving High is Dangerous

Cannabis, just like alcohol, has measurable physiological effects that impair your ability to drive and react quickly in critical situations. Marijuana affects reaction time, short-term memory, hand-eye coordination, concentration, and perception of time and distance. Even if you think you're a better driver when you're're not.

Driving High is Illegal
Consuming any amount of marijuana before or during driving will put you at risk for DUI. A DUI can cost you more than $13,500, in addition to jail time.

  • Driving high is a prosecutable offense — even if you have a prescription.
  • Wait until you're home; it's illegal to use marijuana anywhere in public, including your vehicle. All cannabis products must be in a sealed container and away from the driver area.
  • As with alcohol, there is an established impairment level in Colorado: five nanograms of active tetrahydrocannabinol (THC)—the active psychoactive component of marijuana—per milliliter of whole blood.
