Every DOT-regulated employer — including single-truck owner-operators dispatching out of Charleston — must participate in a random drug and alcohol testing program under 49 CFR Part 382, administered through a Consortium/Third-Party Administrator (C/TPA). Operating without one risks fines that start at $16,000+ per violation.

With automotive, logistics, manufacturing, and aerospace driving demand for CDL drivers around Charleston, South Carolina’s port and automotive freight are major employers of CDL drivers.
