Washington trucking permits
Trip, fuel and oversize/overweight permits for Washington — what the state requires, how it prices them, and how to get them filed.
How Washington prices a permit
In Washington, what you pay turns on how heavy the load is, how far over legal it measures and how far you travel in the state. Because distance is part of it, a short crossing of Washington costs less than running its length.
States do not use a common formula. Washington charges on weight over the limit, per mile, a flat fee by weight band and dimension bands, depending on the permit and the configuration:
- weight over the limit, per mile
- Each increment of excess weight is charged across the miles travelled — long heavy crossings get expensive quickly.
- a flat fee by weight band
- The fee steps up at set weight thresholds and does not change with distance.
- dimension bands
- Length, width and height are read together against a set of bands, and the band you land in sets the fee.
What Washington 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 | Washington fee | Our fee |
|---|---|---|
| Trip Permit | from $25 | $29 |
| Fuel Permit | from $30 | $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. Washington is the authority, not this page — treat these as a guide and the quote as the number.
When you need an oversize permit in Washington
Width and gross weight are federal everywhere — over 102 inches wide or 80,000 lbs and you need a permit in Washington and in every other state. What changes at the state line is height, trailer length and what the axles may carry.
- Height
- 14'
- Semi-trailer length
- 53'
- federal baseline 53'
- Tandem axle
- 34,000 lbs
- federal baseline 34,000 lbs
- Washington allows 14' of height where the federal baseline is 13' 6" — a load that needs a permit elsewhere may be legal here.
Overhangs, single and tridem axles and the full table are on the Washington regulations page.
