What Are South Carolina Oversize Permits?
A south carolina oversize permit is an official authorization issued by the South Carolina Department of Transportation (SCDOT) Oversize/Overweight (OS/OW) Permit Office that allows vehicles and loads exceeding South Carolina’s standard legal size and weight limits to travel on state highways. Any carrier moving oversized or overweight freight across South Carolina without a valid south carolina dot oversize permits faces serious consequences — including fines starting at $100 for a first offense, forced off-loading, vehicle holds, and delayed deliveries.
South Carolina layers a coastal tourism rule on top of its standard travel-hour restrictions that catches many carriers off guard: from Memorial Day through Labor Day, oversize travel on routes between I-95 and the Myrtle Beach area is prohibited on Fridays and Saturdays entirely — a seasonal closure built specifically around Grand Strand beach traffic. Carriers routing freight toward the coast in summer without checking this window are the ones who get stuck waiting out a weekend they didn’t plan for.
AONE Permits manages the entire south carolina oversize overweight permits process — from the south carolina oversize permit login and SCDOT system filing to Myrtle Beach seasonal verification and full provisions compliance. Submit your south carolina oversize permit application through our team and get your permit issued fast, accurately, and rejection-free every single time.

Know Before You Dispatch
South Carolina Oversize Permit Movement Restrictions
South Carolina oversize permit movement restrictions are actively enforced by the South Carolina Department of Public Safety statewide, with additional rush-hour and seasonal restrictions layered into specific corridors. Operating outside approved travel hours, ignoring the Myrtle Beach summer closure, or skipping a required escort results in fines, permit revocation, and forced off-loading at the carrier’s expense. AONE Permits tracks SCDOT’s restriction schedule in real time to keep your South Carolina operation fully compliant.
SCDOT Blackout Holiday Periods
- Memorial Day Weekend — Friday noon through Monday midnight
- Independence Day (July 4th) — restricted on the holiday and adjacent days

- Loads wider than 14' require two pilot/escort cars in South Carolina
- Seasonal load restrictions apply on posted roads during spring thaw (typically February through April)
South Carolina-Unique Requirements
The Myrtle Beach Summer Closure & Self-Issue OS/OW System — What Catches Most Carriers Off Guard
Most states layer urban rush-hour curfews on top of standard travel rules. South Carolina adds something genuinely different: a seasonal closure built specifically around coastal tourism. From Memorial Day through Labor Day, oversize loads are barred from traveling routes between I-95 and the Myrtle Beach area on Fridays and Saturdays entirely — the exact two days when beach traffic peaks heading into and out of the Grand Strand. A carrier hauling freight toward Myrtle Beach on a July weekend without checking this rule can find the entire corridor closed to oversize movement for two full days.
South Carolina also runs one of the more carrier-friendly self-service systems in the Southeast: its OS/OW Self-Issue Multiple Trip Permit lets carriers with non-divisible loads, containerized cargo, or mobile homes generate their own multi-trip permit 24 hours a day, 7 days a week — either through a registered web account or by signing on as a guest user. The system automatically applies default dimensions up to 14′ wide, 13’6″ tall, and 90,000 lbs on 5 or more axles. The catch is that this self-issue permit only covers US, state, and Interstate routes; it explicitly does not cover secondary roads, which require a separate route-specific permit from the SCDOT permit office.
AONE Permits manages both pieces for every South Carolina filing. We check your travel dates against the Myrtle Beach summer restriction before scheduling your route, and we confirm whether your load qualifies for instant self-issue processing or needs a route-specific permit for secondary roads — so your south carolina oversize permits filing reflects the fastest path that’s also fully compliant.
- No oversize travel between I-95 and Myrtle Beach on Fridays/Saturdays, Memorial Day through Labor Day
- SCDOT’s Self-Issue Multiple Trip Permit allows instant 24/7 permit generation for qualifying loads
- Self-issue covers US, state, and Interstate routes only — never secondary roads
- Secondary road travel requires an additional route-specific permit from the SCDOT permit office
- Default self-issue dimensions: up to 14′ wide, 13’6″ tall, 90,000 lbs on 5+ axles
- AONE Permits checks the Myrtle Beach calendar and confirms self-issue eligibility before every filing
Not sure if your summer route toward Myrtle Beach clears the seasonal restriction, or whether your load qualifies for instant self-issue processing? AONE Permits reviews your complete route and gives you clear, exact answers before you apply — one call, zero confusion.
