Nevada commercial vehicle weight limits follow the federal Interstate standard of 80,000 lbs gross, 20,000 lbs per single axle, and 34,000 lbs per tandem axle group. The federal bridge formula (23 U.S.C. 127) applies on all routes. No seasonal weight restrictions on Interstate highways. Oversize and overweight permits are available from NV DOT for loads exceeding standard limits. Verify current road-specific postings with the Nevada DOT before routing heavy loads.
The federal bridge formula limits the weight on any group of axles based on the distance between the outermost axles in the group. It applies in Nevada on all routes where federal standards apply.
W = maximum weight in lbs · L = axle spacing in feet · N = number of axles

No. Nevada does not impose seasonal spring weight restrictions. The arid desert climate means road surfaces do not experience the frost heave and thaw cycles that create spring weight restrictions in northern states.

Nevada allows 42,000 lbs on tridem axle configurations. LCV combinations on designated routes may have different axle weight distributions — verify with NDOT for specific LCV route authorizations.
Large open-pit mining haul trucks in Nevada are off-highway equipment and operate on private mining property under site-specific weight authorizations — they do not travel public highways. However, support vehicles, fuel tankers, and supply trucks serving Nevada mines operate on public highways under standard weight limits with overweight permits where required. Nevada NDOT handles permits for loads serving mine construction and maintenance.
