Starting and running a trucking company in South Carolina

Here's the compliance stack for a trucking company based in South Carolina: who runs each requirement and what to handle before the first load.

The South Carolina carrier stack at a glance

The compliance picture for a South Carolina carrier splits into three layers: the federal baseline every carrier owes, South Carolina's own registrations, and the per-mile programs of the states your routes cross. Here's each layer with its real agency.

• IFTA: South Carolina DMV
• IRP (apportioned plates): South Carolina DMV
• Intrastate program: via South Carolina Office of Regulatory Staff
• Workers' comp: South Carolina Workers' Compensation Commission (threshold ~4 employees)

Interstate: IFTA and IRP for South Carolina carriers

Your IFTA base jurisdiction is South Carolina: the license and quarterly fuel-tax filings go through South Carolina DMV, which issues one license and a set of decals per truck.

Apportioned plates and the cab card come from South Carolina DMV under the International Registration Plan, with annual fees split across the states you run by mileage.

Running intrastate only in South Carolina

Hauling for pay only within South Carolina still requires state registration: start with an intrastate USDOT number, then confirm with South Carolina Office of Regulatory Staff exactly what the state requires before your first in-state load.

Workers' compensation in South Carolina

South Carolina generally requires workers' compensation once you reach 4 employees. With W2 drivers, confirm your exact obligation with South Carolina Workers' Compensation Commission before assuming you're exempt.

Permit states near South Carolina

No weight-distance state borders South Carolina, but long-haul routes still meet them: Oregon's weight-mile tax, New York's HUT, Kentucky's KYU, New Mexico's weight-distance permit, Connecticut's Highway Use Fee, and California's Clean Truck Check all follow the truck, not the base plate. Register before the route, not after the citation.

The federal baseline (every state)

Whatever the state layer looks like, the federal floor is constant: USDOT number, MC operating authority with a BOC-3 process agent for interstate for-hire work, primary liability insurance on file with the FMCSA, UCR registration, Form 2290 heavy-vehicle use tax, the MCS-150 biennial update, and driver-side items like medical cards and drug-and-alcohol consortium enrollment. The full picture, resolved for your specific operation, lives in CabCommand's compliance roadmap.
