South Carolina Truck Bans & Hazmat Routes

Where South Carolina keeps trucks out

South Carolina keeps it simple: no cars-only parkways and no hazmat tunnels. The Ravenel Bridge (US-17) in Charleston sits high over the Cooper River, so it is no low-clearance trap. Your job here is the local stuff. Cities and counties post 'no thru trucks' on residential streets (Richland County near Columbia is one), and SCDOT marks designated truck routes. Hazmat follows 49 CFR 397 designated routes, and the State Transport Police enforce it hard.

Key restrictions

• No cars-only parkways and no hazmat tunnels statewide.
• Ravenel Bridge (US-17, Charleston) is high-clearance, not a low-bridge trap.
• Local 'no thru truck' streets (e.g., Richland County near Columbia); follow SCDOT truck routes.
• Hazmat follows 49 CFR 397 designated routes; State Transport Police enforce.

• Parkway / road ban: No cars-only parkways and no hazmat tunnels. Restrictions are local 'no thru truck' streets and SCDOT designated truck routes; the Ravenel Bridge in Charleston is high-clearance, not a trap.
• Hazmat: No state-specific hazmat tunnel or bridge ban. Placarded loads follow 49 CFR 397 and South Carolina's designated routes, keeping off crowded and residential streets and out of the Charleston port core except for local pickup or delivery. The State Transport Police (SCDPS) run a dedicated hazmat enforcement team.
• Through-truck routes: Cities and counties post 'no thru trucks' on residential streets (Richland County near Columbia is one example) and SCDOT marks designated truck routes. A through truck with no local stop must stay on the network; a delivery may leave it for the shortest path. STAA reasonable access applies.
• Fine: State Transport Police can ticket, place you out of service, and impound for a truck-route or hazmat routing violation; a placarded load off its required route also risks FMCSA/PHMSA civil penalties in the thousands. A bridge strike is on the driver.
