Drug Recognition Experts (DRE) Program

A Colorado Drug Recognition Expert (DRE) is a law enforcement officer trained to recognize impairment in drivers under the influence of drugs other than, or in addition to, alcohol. The International Association of Chiefs of Police (IACP) coordinates the International Drug Evaluation and Classification (DEC) Program with support from the National Highway Traffic Safety Administration (NHTSA) of the U.S. Department of Transportation.

The Colorado DRE program began in 1987.

As of 2019:

  • There are currently 226 active DREs
  • 79 agencies have DREs
  • Of the 226 active DREs, 62 serve with the Colorado State Patrol
