Last reviewed November 12, 2026.

This page summarizes what we could verify from official sources about how South Carolina applies driver vehicle inspection and related vehicle-inspection rules. It is not a complete reprint of South Carolina law.

Interstate operations

If you operate a commercial motor vehicle in interstate commerce to, from, or through South Carolina, the federal Motor Carrier Safety Regulations (FMCSRs) apply, including 49 CFR Part 396 and the DVIR rules in § 396.11 and § 396.13. State rules do not replace those federal interstate requirements. Start with What a DVIR is and who must complete one.

Intrastate operations and variations

Confirm current South Carolina adoption of Part 396, including any intrastate weight threshold or DVIR exception, with the South Carolina Department of Public Safety and by reading the current official South Carolina motor-carrier safety rules.
