New Mexico trucking permits
Trip, fuel and oversize/overweight permits for New Mexico — what the state requires, how it prices them, and how to get them filed.
How New Mexico prices a permit
In New Mexico, 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 New Mexico costs less than running its length.
States do not use a common formula. New Mexico charges on a per-mile rate that changes with distance, weight over the limit, per mile, dimension bands and weight and distance together, depending on the permit and the configuration:
- a per-mile rate that changes with distance
- The rate per mile itself steps at set distances, so the long-haul rate differs from the short-crossing one.
- weight over the limit, per mile
- Each increment of excess weight is charged across the miles travelled — long heavy crossings get expensive quickly.
- dimension bands
- Length, width and height are read together against a set of bands, and the band you land in sets the fee.
- weight and distance together
- A rate per mile that rises with how heavy the load is, so both the weight and the length of the crossing move the price.
What New Mexico 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 | New Mexico fee | Our fee |
|---|---|---|
| Trip Permit | by weight, axles and distance | $29 |
| Fuel Permit | by weight, axles and distance | $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. New Mexico is the authority, not this page — treat these as a guide and the quote as the number.
When you need an oversize permit in New Mexico
Width and gross weight are federal everywhere — over 102 inches wide or 80,000 lbs and you need a permit in New Mexico 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
- 57' 6"
- Tandem axle
- 34,320 lbs
- New Mexico allows 14' of height where the federal baseline is 13' 6" — a load that needs a permit elsewhere may be legal here.
- Semi-trailers may run to 57' 6", longer than the 53' most states allow.
- A tandem axle may carry 34,320 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 New Mexico.
Overhangs, single and tridem axles and the full table are on the New Mexico regulations page.
