Where do I buy a New Mexico oversize permit?

From the Department of Transportation's online permit system, tied to its ports of entry. The permit has to be purchased before you enter the state and carried in the truck, so buy it ahead of the move, not at the border.

Does New Mexico offer an annual oversize permit?

Yes. An annual permit covers a year of excessive height, length, and width and overweight moves up to a published gross-weight cap. Our sourced permit fields carry the fee and the cap.

When can oversize loads move in New Mexico?

By default only in daylight, from shortly before sunrise to shortly after sunset. Movement stops in bad weather and above a set wind speed, weekday rush-hour curfews close named urban routes, and major holidays are no-movement days. Our sourced travel-restriction fields carry the exact times and the wind cutoff.

When does a load need an engineering review in New Mexico?

Once it passes the published gross-weight line, no permit issues until an engineering analysis of the route is complete, and the very heaviest loads are coordinated with the NMDOT Bridge Section. The sourced superload field carries the weight thresholds.

New Mexico Oversize and Overweight Permits

By Evan Reid, Founder of Haul Handbook · Updated Jul 20, 2026

New Mexico legal limits (no permit needed at or under these)

Width: 8 ft8 feet is the legal width before an oversize permit is required.
Height: 14 ft
Gross weight: 80,000 lbLegal gross weight is 80,000 pounds. Within 12 miles of a New Mexico port of entry on the Mexico border, gross weight up to 96,000 pounds is allowed under the border-zone provision.
Length: single_vehicle: 40 ft
Length: combination: 65 ft
Off interstate limits: NMAC 18.19.8 states the legal dimensions above apply before a permit is required; it does not publish a separate off-interstate size and weight table. Legal axle-group weight limits were not published on the pages we checked and are not recorded here rather than invented.

Permit fees

Single trip: Section 66-7-413 NMSA 1978 sets the single-trip permit fee at $25.00 plus, for overweight loads, two and one-half cents for each 2,000 pounds in excess of 86,400 pounds or major fraction thereof multiplied by the number of miles. The permit is issued on payment of the proper fee.
Annual permit: $250
Annual eligibility: Section 66-7-413 NMSA 1978 provides an annual permit costing $250 for a vehicle whose gross weight does not exceed 140,000 pounds, authorizing excessive height, length and width and excessive weight up to that limit for the permit year.

Single-trip permit fee schedule

A single-trip permit stacks a base fee with a weight-tiered maintenance fee, and the heaviest loads add a supervision fee.

New Mexico single-trip oversize permit fee components
Fee component	Applies to	Amount
Base single-trip permit fee	All single-trip oversize/overweight permits	$25
Overweight mileage component	Loads over 86,400 lb gross weight	Not confirmed

Escort thresholds

Dimension	Threshold	Escorts	Where the escorts ride	Police escort
width	at or over 14 ft	1	Escort required; specific front/rear placement is governed by the NMDOT escort vehicle map.	Not confirmed
width	20 ft or wider	2 or more	Flagmen are mandatory and a police escort may be required.	may be required
length	over 110 ft 1 in up to 120 ft 1 in	1	One escort required.	Not confirmed
length	over 120 ft 1 in	2	Two escorts required.	Not confirmed
height	over 16 ft	as required	An escort vehicle or a person other than the driver may be required to make immediate height-clearance verifications.	Not confirmed

What the escort itself has to be

Hitting the threshold is only half of it. The escort vehicle, its equipment, its driver's certification and where it rides are all regulated, and the carrier is the one holding the permit when they are not met.

Overhang permit thresholds: A front overhang of 3 feet or more, or a rear overhang of 7 feet or more, beyond the vehicle requires a permit (NMAC 18.19.8).
Escort route map: The exact escort/pilot-car placement for wide loads is determined by the NMDOT escort vehicle map referenced in the permit portal.

Escort rules beyond the thresholds

Knowing when you need an escort is half of it. These are the New Mexico rules on who may run one, what the vehicle has to carry, and how the move is conducted.

Overhang permit thresholds: A front overhang of 3 feet or more, or a rear overhang of 7 feet or more, beyond the vehicle requires a permit (NMAC 18.19.8).
Escort map: The exact escort/pilot-car placement for wide loads is determined by the NMDOT escort vehicle map referenced in the permit portal.

Travel restrictions

Daylight only: By default, movement is allowed only from 30 minutes before sunrise until 30 minutes after sunset.
Curfews: Weekday urban rush-hour restrictions apply: no movement 7 to 9 a.m. and 4 to 6 p.m. on interstates and highways in Santa Fe, Las Cruces and Espanola; and no movement 7 to 9 a.m. and 4 to 7 p.m. in Albuquerque and Rio Rancho.
Weekend / holiday: No movement is allowed on New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, Christmas Day, and other days designated by the department.
Wind / weather: No movement is allowed during inclement weather; oversize vehicles may not move when wind speeds reach 25 miles per hour or more.

Superload and beyond-permit review

Loads past the standard single-trip permit thresholds get individual state review rather than an off-the-shelf permit.

No special permit is issued for a load exceeding 170,000 pounds gross weight unless an engineering analysis has been conducted for the proposed route (NMAC 18.19.8). Superloads of 200,000 pounds gross weight and above are coordinated with the NMDOT Bridge Section, (505) 795-4317.

Engineering analysis over lb: 170,000
Bridge section review over lb: 200,000

Legal limits before you need a permit

New Mexico publishes a legal width, height, and length by configuration, and a legal gross-weight ceiling. Stay inside them and you run without a permit; cross any one and you need one. A border-zone rule lifts the gross-weight ceiling within a short distance of a port of entry on the Mexico border, which matters if you cross there.

The state code we read publishes these as the limits that apply before a permit is required and does not post a separate off-interstate size and weight table or legal axle-group weights, so we record only what is published rather than importing figures.

Single-trip and annual permits

A single-trip permit covers one move over the legal limits. Pricing starts from a base permit fee, and for overweight loads it adds a mileage-based component that scales with how far over the weight ceiling the load runs. For repeated work, an annual permit covers a year of excessive height, length, width, and overweight moves up to a published gross-weight cap.

Dealers can self-issue a couple of narrow permit types for manufactured homes and implements of husbandry. Our sourced fee fields carry each amount, and the mileage-based overweight math sits in the single-trip fee schedule rather than in this prose.

Escort and flagger requirements

Escorts phase in by dimension. Crossing the published width line calls for an escort, and the widest loads add mandatory flaggers and can draw a police escort. Long loads need escorts once they pass the published length lines, and tall loads can require someone other than the driver to verify height clearance. Front and rear overhang past the published limits also triggers a permit.

The exact escort placement for wide loads follows the state's escort vehicle map referenced in the permit system, so the map, not a printed guess, controls where a pilot car rides.

When oversize loads can move

New Mexico runs a daylight-first regime. By default an oversize load moves only from shortly before sunrise to shortly after sunset. Movement stops in inclement weather, and there is a wind cutoff above which oversize vehicles may not move at all. On top of that, weekday rush-hour curfews close named urban stretches, and major holidays are full no-movement days.

These rules are set in the state code, so plan a route around the daylight window, the weather and wind limits, and the rush-hour curfews in Albuquerque, Rio Rancho, Santa Fe, Las Cruces, and Espanola.

Superloads and engineering review

Past a published gross-weight line, New Mexico will not issue a permit until an engineering analysis of the proposed route is done. The very heaviest loads are coordinated with the NMDOT Bridge Section, which runs the structural review for those moves. Build that review time into the schedule, because a superload cannot move on a whim.

The exact weight lines for the engineering analysis and the bridge coordination are sourced fields, so the thresholds come from the state code rather than this paragraph.

How to read this page

A value reading "Not confirmed" means we could not verify the figure on an official agency page at review time, so it stays open rather than guessed. Superload moves above the standard permit thresholds get individual review by the state; contact the permit office named on this page.
