Quick answer

Do I need a permit to move an oversize load in New Mexico?

Yes, once the load is wider than 8 ft 6 in, taller than 14 ft or heavier than New Mexico's limits, which allow 86,400 lbs gross and 21,600 lbs on a single axle. NMDOT issues permits through NM-OPS for $25, and loads over 86,400 lbs add a ton-mile fee for every mile in the state. Permits must be bought online before entering New Mexico.

Heavy haul and oversize freight in New Mexico

New Mexico's heavy freight crosses the state on I-40 between Texas and Arizona through Albuquerque, on I-10 through Las Cruces and Deming, and on I-25 north through Santa Fe toward Colorado. Oilfield equipment in the Permian Basin around Hobbs and Carlsbad, energy and mining machinery, and loads between Texas and California make up much of it. We book carriers for moves within New Mexico or through it.

New Mexico allows more weight than most states before a permit is needed, but its route rules are detailed. NMDOT's escort map lowers the escort width on many two-lane routes and in 27 cities, Albuquerque, Santa Fe and Las Cruces close to permit loads at rush hour, and oversize loads stop in winds of 25 mph or more. We check the map and the construction list before quoting.

What are the legal size and weight limits in New Mexico?

Under the oversize load regulations in New Mexico, a load above any of these limits needs a state oversize or overweight permit.

Width	8 ft 6 in
Height	14 ft
Semitrailer length	57 ft 6 in
Gross weight	86,400 lbs
Single axle	21,600 lbs
Tandem axle	34,320 lbs

Limits are set by NMSA 66-7-402 to 66-7-410. New Mexico's 86,400 lb gross and 21,600 lb single axle apply on federally designated routes, above the federal 80,000 and 20,000 lbs.

Who issues New Mexico oversize permits?

The NMDOT Permit Office in Santa Fe issues permits through NM-OPS, and the permit has to be in hand before the load crosses into the state; ports of entry handle only trip-tax and fuel permits. A single trip permit covers one one-way move over 5 days, and an insurance certificate has to be on file first.

The NMDOT Bridge Office reviews every self-propelled load and any load over 170,000 lbs with a route engineering investigation. City streets and federal or tribal roads need their own permission, and the weight-distance tax or trip tax applies separately from the permit.

What do New Mexico oversize and overweight permits cost?

request_quote Single trip permit, oversize or overweight: $25.
request_quote Over 86,400 lbs: 2.5 cents for each 2,000 lbs over, per mile traveled in New Mexico.
request_quote Over 170,000 lbs: NMDOT can add the cost of its own engineering analysis.
request_quote Annual multiple trip permit: $250, for loads up to 14 ft wide, 15 ft high, 120 ft long and 140,000 lbs.
request_quote The weight-distance tax or trip tax is charged separately, and its rates rose 35% in July 2026.

Worked example: a 120,000 lb load over 300 miles

The load is 33,600 lbs over 86,400, which counts as 17 units of 2,000 lbs. At 2.5 cents per unit per mile, 300 miles costs 17 x $0.025 x 300 = $127.50, plus the $25 permit, for $152.50 before the weight-distance or trip tax.

Seasonal weight limits in New Mexico

New Mexico has no frost law. The Transportation Commission and local authorities can post size and weight limits, and running a heavy load on a road softened by moisture is an offense in its own right. The seasonal factors are winter weather and wind: some mountain highways close or are not recommended in winter, so routes are checked on nmroads.com before a cold-season move.

FAQ

New Mexico Oversize Load Questions

Permits, escorts and travel rules for oversize moves in New Mexico.

How much is a New Mexico oversize permit?

NMDOT charges $25 for a single trip oversize or overweight permit. Loads over 86,400 lbs gross add 2.5 cents for every 2,000 lbs over that weight, multiplied by the miles driven in New Mexico. Annual multiple trip permits cost $250, and the weight-distance or trip tax is paid separately.

How much weight can a truck carry in New Mexico without a permit?

More than in most states: 21,600 lbs on a single axle, 34,320 lbs on a 4 ft tandem rising with spacing, and up to 86,400 lbs gross on federally designated routes. A typical five-axle tractor-semitrailer reaches about 80,460 lbs at 49 ft 6 in or more between its first and last axles.

When does a New Mexico load need an escort?

On most highways from 14 ft wide, with NMDOT setting the number on the permit. The escort map lowers that to 13 ft 6 in on Group A routes and 12 ft on Group B routes, 27 cities require escorts off the Interstate, and length adds one escort over 110 ft and two over 120 ft.

Can oversize loads travel at night in New Mexico?

Only with continuous movement on the permit, which NMDOT grants for loads up to 10 ft wide, 14 ft 6 in high, 120 ft long and 140,000 lbs, with lights visible at 500 ft. Larger loads move in daylight, and no permitted load moves on a listed holiday or in bad weather.

What is a superload in New Mexico?

Any load over 170,000 lbs gross needs a route engineering investigation of the roads, bridges and culverts before a permit is issued. NMDOT reviews the applicant's analysis or runs its own and can add its cost to the fee, and the result can set speed limits at structures or change the route.
