Truck weight limits
New Mexico
✓ Sources verifiedEditorial review pending credentialed reviewer2 primary sources
New Mexico allows 21,600 lb on a single axle — above the federal 20,000 lb — with an 11,000 lb per-wheel limit. Tandem weight is table-driven by axle spacing rather than a fixed figure, and the gross weight table reaches 86,400 lb at 56 feet or more. No 80,000 lb cap appears in the New Mexico statutes at all; that limit binds on Interstates through federal law.
