Key Points:

• DUI offenses involving drugs other than alcohol in Pennsylvania have risen significantly, from 11% in 2007 to 36% in 2025, reflecting changing substance use trends and increased police focus on drug-impaired driving.
• Lancaster County has 13 certified drug recognition experts (DREs) among its police forces, with officers like Sgt. Tyler Weinoldt conducting numerous evaluations to identify drug impairment in drivers.
• DRE training includes a rigorous classroom and certification process in Philadelphia's Kensington area, where officers evaluate volunteers under the influence of various substances, many of whom are then offered rehab opportunities.
• Drug recognition experts assess impairment across seven drug categories, using observable signs and symptoms to differentiate drug effects from medical conditions that may mimic impairment.
• Recent trends show a resurgence of methamphetamine use and increased driving under the influence of cannabis, including among medical marijuana cardholders who may mistakenly believe they can drive safely while impaired.
