An Act amending Title 75 (Vehicles) of the Pennsylvania Consolidated Statutes, in licensing of drivers, further providing for chemical testing to determine amount of alcohol or controlled substance.

SB 735 amends Pennsylvania's Vehicle Code concerning chemical testing for driving under the influence (DUI). It expands the types of impairment for which other evidence can be introduced in DUI cases to explicitly include drugs alone, or drugs in combination with alcohol. A key provision allows testimony from a certified "drug recognition expert" to be admissible as evidence of impairment in judicial proceedings. This bill defines what constitutes a "drug recognition expert" and directly affects drivers suspected of impairment and the legal process for DUI cases.
