Legal Load Limits in New Mexico

The following are the legal weight and dimensions limits in New Mexico before a load requires trucking permits.

  • Length: 65’on non-designated highways and 57′ 6″ max trailer length for all other areas.
  • Height: 14′
  • Width: 8′ 6″ or 102″ depending on route.
  • Weight: 80,000 lbs. on interstate roads and 80,640 lbs. on all others.
  • Overhang: We do not have any information on the legal overhang limits. If you have information please share it with others below.

Routine Trucking Permits in New Mexico

  • Length:  There is no clarification on length. We do know that over 190′ is classified as a superload. Routing would be the issue. Please share your expertise below.
  • Height: 14′
  • Width: Routine limits on width is another bloodstone.  Routing (mainly sub-routing) is complicated in this state.
  • Weight: These are the routine weights that are allowed on the Interstates in New Mexico. Still routing is the determining factor. Single axle; 23,000 lbs, tandem axles; 46,000 lbs, tridem axles; 60,000 lbs, quadem axles; 68,000 lbs. Roads other than the Interstate all depend on your axle spacings. Gross weights are: 5 axles; 105,000 lbs, 6 axles; 119,000 lbs, 7 axles; 127,000 lbs, 8 axles; 150,000 lbs. Of course, all of this is totally dependent on the New Mexico DOT so do not assume anything as it seems they want to review any shipments that are pushing the upper limits as they hold back information so it’s “pending approval”.
  • Overhang: We do not have any information on the legal overhang. If you can help please comment below.

Superload Information in New Mexico

  • Length: anything over 190′ long.
  • Width: 20′ wide for sure. Possibly less on sub-routes.
  • Height: We have no number yet.  The maximum routine is 14′ but that is pretty low. We would think that 17′ would be superload height based on the information we have on this state but routing is everything when it comes to height.
  • Weight: 200,000 pounds and you are a superload.

Travel Times & Restrictions in New Mexico

The sunrise to sunset rule applies in the state of New Mexico. Sunday travel is not allowed, and holiday restrictions apply (if overweight interstate travels only with a pilot car). For example, if the holiday is on a Friday, you can only travel until sunset on Thursday. If the holiday is on a Saturday, you can not travel past Friday at sunset. If the holiday falls on a Saturday, you can’t resume travel until Tuesday. In addition, travel is not permitted on the following holidays: 

  • New Year’s Day
  • Memorial Day
  • Independence Day
  • Labor Day
  • Christmas Day
  • Thanksgiving Day

NOTE: In the cities of Albuquerque, Espanola and Santa Fe you can not travel from the hours of 7 – 9 AM and 4 – 6 PM as high traffic density is the worst during this time.

When Are Pilot Cars Required in New Mexico?

Pilot cars (escort vehicles) are required for shipments that exceed 14′ in width and can be even lower depending on the route you wish to travel.  Pilot cars (escorts) are required for loads exceeding 14′ 6″ on any restricted highways. See the pilot car (escort vehicle) map developed by the New Mexico DOT, which will furnish all pilot cars (escort vehicles) with a complimentary map if you ask. Over-length shipments may require a pilot car (escort) for shipments over 90′ in length overall. If you are over 110′ overall, you will be required to have 2 pilot cars (1 front & 1 rear). If the width of the load exceeds 20′ wide, you will be required to have a police escort and flag person that is certified to control traffic. The maximum height is 16′. If you are over this height, you will be required to have a high-pole pilot car (escort vehicle).

Pilot Car Certifications Required in New Mexico

At the New Mexico DOT port of entry, your pilot car (escort vehicle) will be required to undergo an inspection for certification by the New Mexico DOT while operating in their state. The driver is  required to show the following equipment and documentation in/on the vehicle for inspection purposes:

  • Condition of vehicle tires must be excellent and the wheelbase of the vehicle must be a minimum of 100″ and have a rated capacity of no more than 1 and 1/2 ton vehicle.
  • Two-way radio or CB radio units that are capable of transporting well over 10 miles minimum.
  • 2 amber flashing or strobing lights on the two most outer edges of the vehicle that are visible 360 degrees from a distance of no less than 500′. Headlamps are required to be turned on as well when working.
  • At least 1 “OVERSIZE LOAD” sign must be displayed on the vehicle. This sign must have a yellow background with minimum dimensions of 5′ in width and 12″ in height with black letter thickness no less than 1″ thick. Best if mounted on top but can be mounted to the rear if chasing or front if leading.
  • A minimum of 2 florescent orange-colored safety flags no less than 12″ in length on any side.
  • Fire extinguisher with type A, B, and C rating and a minimum of 2 1/2 pounds (5 or larger is suggested).
  • 3 reflective road triangles and 8 ignitable road flares.
  • Safety-colored vest or jacket.
  • The vehicle must display the company name, address, and contact information on both sides of the vehicle. New Mexico does not allow any logo shapes that resemble law enforcement/vehicles.
  • Certificate of insurance meeting the minimum requirements for New Mexico DOT which are $50,000, $100,000, and $25,000.

The New Mexico DOT inspections are annual inspections and the duration of validity is determined by the expiration date on the insurance certificate or 1 year, whichever is first.
