Permits Valid For:

Single Trip Permits are valid for three (3) consecutive days.

Operating Time:

Permitted loads are allowed travel from Sunrise to Sunset, Monday through Friday.  If loads are permitted for weight only, continuous travel is allowed twenty-four (24) hours a day, Monday through Friday.  Permitted loads not exceeding 12' wide x 15' high, and/or 120,000 lbs. will also be granted continuous travel, but this must be requested on permit.

Weekend Travel

Permitted loads are allowed travel from Sunrise to Sunset on Saturdays.  Travel is restricted on Sundays.

Divisible Loads

Permitted loads must be reduced to their smallest possible dimensions and weights.  A permit will not be issued for loads that are reducible, or that can be shifted to reduce shipping dimensions.  Pieces that have been removed must be shipped as a separate load.


Blades, buckets, attachments, etc. may be hauled intact provided that they are blocked, and angled in a manner that reduces the dimensions as low as possible so long as they do not cause the load to be overweight.

Restricted Travel

Time and restrictions are determined by each city that a permitted load is traveling through.  Each city should be contacted to determine travel restrictions if necessary.  No travel is allowed during inclement weather.  Inclement weather may include ice and snow covered highways, rain, snow fog, smog, sleet or dust.  High winds that cause dust storms, or wind-force that is sufficient to cause the load to sway are also considered inclement weather as well.  Travel as a convoy is prohibited.  Vehicles that are traveling under over-size permit authority requiring an escort will require that each load have its own individual escort.  Escort cars cannot be shared between multiple loads traveling together.

There are no Seasonal Weight Restrictions in the State of New Mexico.
