Trenton, New Jersey Mobile Drug & Alcohol Testing
NJ State Capital · Government Contractors · NJ Transit FRA · I-95 FMCSA · Pharma Corridor — Mobile collections throughout Mercer County.
Trenton is New Jersey's state capital — a center of government contracting, pharmaceutical manufacturing (Bristol-Myers Squibb's historical NJ campus nearby), and a critical I-95 CDL corridor node connecting New Jersey to Philadelphia and the Mid-Atlantic. NJ Transit's River Line and commuter rail pass through Trenton, adding FTA and FRA obligations. The Delaware River crossing generates significant interstate CDL traffic. OnSite Employer Testing covers Mercer County and the Trenton-Hamilton-Ewing corridor — dispatching to government facilities, pharma campuses, and transportation operations.
OnSite Employer Testing coordinates mobile drug testing collections at your Trenton-area facility, yard, terminal, or job site. We do not operate a clinic. Review how it works or browse all locations we serve across the region.
