Legal load limits.

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.

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, tridum 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.

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.

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). If the holiday is on a Friday then you can only travel until sunset on Thursday. If the holiday is on a Saturday you can not travel past Friday at sunset.  Resuming travel. If the holiday falls on a Saturday you can’t resume travel until Tuesday.

When pilot cars are required in New Mexico.

Pilot cars (escort vehicles) are required for and 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 of the restricted highways, see the pilot car (escort vehicle) map developed by the New Mexico DOT which will furnish all pilot cars (escort vehicles) a complimentary map if you ask. Over-length shipments may require a pilot car (escort) for shipments in excess of  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.
