New Mexico Oversize Permits Duration

Oversize permits in New Mexico have a validity of five days. Additionally, these permits can be obtained at Ports of Entry, as long as the size of the load does not necessitate a bridge check or route survey.

Operating Time

Travel is permitted from half an hour before sunrise to half an hour after sunset, Monday through Saturday. For overweight-only loads, continuous travel is allowed. Continuous travel is also permitted if the dimensions do not exceed 10 feet in width, 14 feet 6 inches in height, 120 feet in length, and/or 140,000 pounds in weight.

Escort Conditions for New Mexico Oversize Permits

Length:

  • Over 90′ – one escort
  • Over 110′ – two escorts

  • Over 14′ – 1 escort (a few routes require an escort for over 12′ wide)

Height:

For heights exceeding 16 feet, one escort and a route survey are required. Some routes may necessitate a route survey for lower heights as well.

Miscellaneous:

Bulldozer blades and arms exceeding 14 feet in width (measured at right angles to the trailer axis) must be detached and transported in a manner that avoids creating a safety hazard. If dozer blades are shorter than 14 feet wide, they may be hauled without detachment, provided the dozer is securely supported. Removable items such as buckets, blades, counterweights, etc., must be taken off, but can be transported with the load. If the load would be overweight with or without the blade, the blade can be detached and hauled on the same trailer; this information should be specified in the permit. For wide loads, side mirrors must extend far enough to prevent the view from being obstructed by the load.

Signs, Flags & Lights:

For any Oversize, overweight, or overweight-only load, “Oversize Load” or “Wide Load” signs are mandatory on the front of the towing unit and the rear of the load. Red flags, each at least 12 inches square, must be attached to the front right and left sides of the towing unit, as well as to each corner of the load. Towing vehicles pulling oversize loads exceeding 12 feet wide may display an amber rotating flashing beacon atop the cab.
