South Dakota trucking permits
Trip, fuel and oversize/overweight permits for South Dakota — what the state requires, how it prices them, and how to get them filed.
What South Dakota 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 Dakota fee | Our fee |
|---|---|---|
| Trip Permit | from $15 | $29 |
| Fuel Permit | from $20 | $29 |
| Oversize / Overweight | from $36 | $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 Dakota 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 Dakota
Over 102 inches wide or 80,000 lbs gross, a load needs a permit in South Dakota as it would anywhere. Height, trailer length and axle weight are where states differ, and here is where South Dakota sits.
- Height
- 14'
- Semi-trailer length
- 53'
- 53' in most states
- Tandem axle
- 34,000 lbs
- 34,000 lbs federal Interstate limit
- South Dakota allows 14' of height. The strictest states stop at 13' 6", so a load that needs a height permit in those may be legal here.
Overhangs, single and tridem axles and the full table are on the South Dakota regulations page.
