New Mexico Oversize & Overweight Permits

When New Mexico needs a permit

New Mexico permits over 8'6" wide, 14' high, or 80,000 lb (NMSA 66-7-413). One escort starts at 14' wide, two past 110' long, and State Police plus a flagman ride at 20' wide. A self-issued permit is capped at $15 and single-trip oversize runs about $25, with a required police escort adding a daily charge. Travel is daylight only, Monday through Saturday, and the state parks you when wind tops 25 mph or visibility drops under 1,000 feet.

Thresholds, escorts, and curfews

• Legal max before a permit: Permit needed over 8'6" wide, 14' high, 80,000 lb, or past legal length (57'6" on designated highways, 65' overall elsewhere).
• Escort / pilot car: One escort over 14' wide (some routes require one under 14' depending on the route), one over 90' long and two over 110'. A pole car and route survey over 16' high. Police escort plus a flagman at 20' wide or more. Confirm on the permit.
• Superload: Over about 16' wide or 16' high, or a very heavy non-divisible load, New Mexico runs advance route and structural review before it issues, several business days depending on the load.
• Travel curfew: Daylight only, a half hour either side of the sun, Monday through Saturday. Overweight-only loads get continuous travel, as do loads within 10' wide, 14'6" high, 120' long, 140,000 lb. Albuquerque, Santa Fe, and Espanola hold loads 7-9 a.m. and 4-6 p.m. (Santa Fe adds 11:30 a.m.-1:30 p.m.). No moves on major holidays, or when visibility drops under 1,000 ft or wind hits 25 mph.
• Permit fee: Self-issued permits are capped at $15 by statute; a single-trip oversize commonly runs about $25, and a Department of Public Safety special/escort permit is priced separately (statute allows up to $250). A required State Police escort adds a daily charge. Annual permits are available for repeat runs.
