New Mexico · Oversize & Overweight

New Mexico Oversize & Overweight Permits filed with NMDOT for you, 24/7

New Mexico allows 14 ft of height and up to 86,400 lbs on federal designated routes, but a load over 8 ft 6 in wide or the legal length or weight needs an NMDOT permit, bought online through NM-OPS before the truck enters the state. Ports of entry do not sell oversize permits, and escort vehicles must be New Mexico-certified. Send us the load and route: our permit desk quotes the price and files it for you.

What we check before filing in New Mexico

  1. Escorts certified before the line

    New Mexico wants escort vehicles certified by NMDOT or DPS before they enter. If one is not, the load waits outside the state while the escort gets certified at a port. We confirm certification before dispatch.

  2. The permit comes before the border

    An oversize permit has to be bought online before the truck enters New Mexico, and a port cannot sell one. We file it while the truck is still on the way.

  3. Curfews by city and milepost

    Albuquerque and Rio Rancho hold permitted loads until 7 p.m. on weekdays, the other listed cities and corridors until 6 p.m. We time every crossing on the route.
