Mobile DOT Drug and Alcohol Testing

Our mobile DOT drug and alcohol testing in SC is designed for fleets and safety‑sensitive operations that cannot afford downtime or compliance mistakes. We bring certified collectors directly to your yard, terminal, or job site for on‑site specimen collection - urine or oral fluid - so drivers stay on the clock and routes stay on schedule.

From South Carolina to on‑site DOT‑compliant testing in NC and discreet drug testing for the transportation industry in Georgia, we follow every DOT protocol, maintain airtight chain of custody, and document each step for regulatory‑compliant workplace testing. Post‑accident, reasonable suspicion, return‑to‑duty, and follow‑up collections are all handled on your turf, on your timetable.

 
With true 24/7 mobile drug testing in South Carolina, supervisors have one call to make when an incident occurs after hours or on the road. We arrive on‑site quickly, work discreetly around your operation, and help you demonstrate that you acted promptly, properly, and in full alignment with DOT standards.
