DRE Instructor

Drug Recognition Expert (DRE) Instructor Course


California’s Drug Evaluation and Classification Program (DECP) is an effective means of identifying and prosecuting drug impaired drivers. Drug Recognition Experts (DRE) have gained acceptance and approval throughout the world due to their accuracy and effectiveness.

The California Highway Patrol (CHP) has been designated as the statewide DECP coordinator for the State of California. The resources coordinated by the CHP on a statewide basis assists the National Highway Traffic Safety Administration in the expansion of the DECP to other states as well as within California by providing training in drug detection to law enforcement personnel.

California’s Drug Recognition Expert (DRE) program leads the country with the largest number of certified DREs. Much of this success can be attributed to the quality and guidance given by California DRE Instructors during the classroom instruction and field certification processes. Because of the highly technical nature of the functions performed by the DRE, only persons experienced in the techniques of drug influence evaluations should become instructors in the DRE program.

DRE Instructors are tasked with instructing for all California agencies, participating in statewide training events, and maintaining a profound knowledge of DRE protocol and current drug trends. Accomplishing this task requires tremendous support and flexibility from the DRE Instructor’s agency.
