South Carolina trucking permits
Trip, fuel and oversize/overweight permits for South Carolina — what the state requires, how it prices them, and how to get them filed.
How South Carolina prices a permit
In South Carolina, what you pay turns on how far over legal it measures. Distance does not enter into it — a four-mile clip of the corner costs the same as running South Carolina end to end.
States do not use a common formula. South Carolina charges on a flat fee by dimension, depending on the permit and the configuration:
- a flat fee by dimension
- Priced on how far over legal the load measures, not on how far it travels.
What South Carolina permits cost
The state's own fee, plus what we charge to prepare and file it. Your total depends on the trip, so the quote is the number that counts — these are the floors we hold on file.
| Permit | South Carolina fee | Our fee |
|---|---|---|
| Trip Permit | from $40 | $39 |
| Fuel Permit | from $40 | $29 |
| Oversize / Overweight | by weight, axles and distance | $39 |
A handling fee applies to each permit line. Nothing is charged until you have seen the total.
Fees and limits on this page were last checked in September 2026. States change fee schedules, legal limits and office hours without notice, and some fees depend on details we only know once you tell us the trip. South Carolina is the authority, not this page — treat these as a guide and the quote as the number.
When you need an oversize permit in South Carolina
Width and gross weight are federal everywhere — over 102 inches wide or 80,000 lbs and you need a permit in South Carolina and in every other state. What changes at the state line is height, trailer length and what the axles may carry.
- Height
- 13' 6"
- federal baseline 13' 6"
- Semi-trailer length
- 53'
- federal baseline 53'
- Tandem axle
- 40,000 lbs
- A tandem axle may carry 40,000 lbs here, above the 34,000 lbs federal figure — so a load that is overweight on the axles in a neighbouring state can be legal in South Carolina.
Overhangs, single and tridem axles and the full table are on the South Carolina regulations page.
