Permits valid for three days. Drivers usually order NM permits through the Sammons Permit Office, but they can also be purchased at Ports of Entry provided the size of the load does not require a bridge check or route survey.

The blade can be detached and hauled with the dozer on the same trailer if the load would be overweight with or without the blade. It should be stated on the permit. On wide loads, side mirrors must extend far enough to avoid view being blocked by the load.
SIGNS, FLAGS & LIGHTS:
"Oversize Load" or “Wide Load" signs required on the front of the towing unit and on the rear of the load. Red flags at least 12" square must be affixed to the front right and left sides of the towing unit and to each corner of the load. Towing vehicles pulling oversize loads that exceed 12' wide may display an amber rotating flashing beacon atop the cab.
