New Mexico Truck Permits for trip tax, weight-distance, fuel, oversize & overweight
A truck over 26,000 lbs owes New Mexico's weight-distance tax: carriers register yearly for a Weight Distance Permit, and without one a trip tax is charged by miles and gross weight. Without IFTA, a temporary special fuel permit covers up to 48 hours. Oversize and overweight permits come from NMDOT, online only and before the truck enters. Tell us the truck, load and route, and we file every New Mexico permit the trip needs.

New Mexico and its neighbors
How New Mexico permits differ from the states around it
A route from Texas, Oklahoma or Colorado meets a different tax and escort system at the New Mexico line.
A distance tax instead of a timed trip permit
New Mexico charges trucks over 26,000 lbs by distance and weight. Texas, Oklahoma and Colorado sell trip permits by the hour, from 72 hours.
Escorts from 14 ft, like Texas
New Mexico and Texas both require escorts from 14 ft wide, though New Mexico's escort map can ask for them on narrower loads. Oklahoma starts at 12 ft.
The same height as Texas
New Mexico and Texas allow 14 ft without a permit. Colorado allows 14 ft 6 in and Oklahoma 13 ft 6 in.
Escorts certified before entry
New Mexico wants escort vehicles certified by NMDOT or DPS before they cross the line. Colorado accepts certificates from Arizona, Florida, Minnesota, Oklahoma, Utah and Washington.

FAQ
New Mexico permit questions
Who pays New Mexico's weight-distance tax?
Carriers running trucks over 26,000 lbs. They register every year for a New Mexico Weight Distance Permit; a truck without one pays a trip tax based on its miles and gross weight.
When does a prepaid New Mexico trip tax permit expire?
Six months after it is issued by the Taxation and Revenue Department. We buy it for the dates of your run so it is valid when the truck arrives.
What does New Mexico's temporary special fuel permit cover?
One entry and one exit within up to 48 hours, for a carrier without IFTA. We file it with the trip tax permit so both are ready at the line.
Which New Mexico ports of entry stay open around the clock?
Anthony and Lordsburg on I-10 and Gallup and San Jon on I-40, four of the state's 12 ports. They sell trip tax and fuel tax permits; oversize and overweight permits are online only, before entry.
Can one order cover New Mexico taxes and an oversize permit?
Yes. Give us the truck, load and route once: we file the trip tax and fuel permits, the NMDOT oversize permit and the permits for every other state you cross, at any hour.
