MI SB0207

Defines "standardized field sobriety test" as a test validated by the National Highway Traffic Safety Administration and administered in substantial compliance with NHTSA standards.

Authorizes drug recognition expert peace officers in participating counties to require preliminary oral fluid analysis if they have reasonable cause to believe a driver consumed a controlled substance or possesses a Schedule 1 controlled substance.

Makes preliminary oral fluid analysis results admissible in criminal prosecutions and administrative hearings to establish arrest validity or rebut conflicting testimony about substance presence.

Establishes that refusing a preliminary oral fluid analysis is a civil infraction, with commercial motor vehicle operators subject to a mandatory 24-hour out-of-service order for refusal.

Allows qualified persons to testify about standardized field sobriety tests, including the horizontal gaze nystagmus (HGN) test, upon proper foundation of qualifications, effective September 22, 2016.
