**Rationale:** The DRE program was developed to provide law enforcement officers with a
standardized, systematic method for recognizing and evaluating impairment in drivers suspected
of being under the influence of drugs other than, or in addition to, alcohol. The DRE is not a
medical diagnostician, does not replace chemical testing, and the primary objective is
identification and evaluation—not arrest. This question tests foundational comprehension of the
program's core mission and scope of practice.
