Vehicle marking/Identification - South Carolina

Federal regulations

South Carolina has adopted Sec. 390.21 of the Federal Regulations.

Commercial motor vehicles operating solely in intrastate transportation must display their USDOT number followed by “SC” on all vehicles.

Applicability

Sec. 390.21 applies to a commercial motor vehicle and its driver, operating in intrastate commerce with a gross vehicle weight, gross vehicle weight rating, gross combination weight, or gross combination weight rating equal to or exceeding 26,001 pounds, or a commercial motor vehicle and its driver, transporting hazardous materials required to be placarded.

Additional requirements

A carrier regulated by the Public Service Commission must display its name (or trade name), principal place of office, and PSC I.D. number on both sides of the vehicle in letters and figures at least 3 inches high.

Example: ABCD Trucking Company Nichols, South Carolina

SCPSC #1234

Interstate

All commercial motor carriers (for-hire and private) operating interstate are subject to the marking requirements of 49 CFR 390.21 which requires all CMVs to display, on both sides of the power unit, the US DOT number and the legal name of the business entity that owns or controls the motor carrier operation, or the “doing business as” (DBA) name, as it appears on the Form MCS-150.

Any new or used commercial vehicles added to a motor carrier’s fleet must be identified with the US DOT number and single trade name before being put into service.

The regulations do not require the city, state, or MC number to be displayed on the vehicle.
