Many courts will not qualify a DRE as an expert unless he or she has received training from a medical professional. This course will provide the medical and scientific foundations of the various components of the DRE protocol, including the eye tests, vital signs and psychophysical and divided attention tasks. Common medical conditions, rule-outs and alternative explanations for observed signs will be discussed. The course will include numerous videos, classroom demonstrations and an alcohol workshop.

This program is intended for officers who are Certified Drug Recognition Experts (DREs) and prosecutors who handle DUI and drug cases as well as DUI instructors and SFST practitioners.
