MAXIMUM LEGAL WEIGHT ALLOWED
Texas has established size and weight limits for vehicles and loads moving with or without oversize and/or overweight permit on Texas roadways and bridges.
GROSS VEHICLE WEIGHT
! The basis for maximum legal weight is the number of axles. This information, in conjunction with the Permissible Weight Table, is used to determine maximum legal weight for a vehicle.
! An axle group must have a minimum spacing of 40 inches between axles within the group.
W=500 [(LN/(N-1)) +12N+36]
L=length and N=number of axles
MAXIMUM PERMIT WEIGHT ALLOWED
The maximum permit weight for an axle or axle group is based on 650 pounds per inch of tire width or the following axle or axle group weight, whichever is the lesser limit.
TANDEM (TWO AXLE)
TRIDEM (THREE AXLE)
QUADREM (FOUR AXLE)
QUINT (FIVE AXLE)
SIX OR MORE AXLES
Determined by MCD based on engineering study of the equipment and measurements.
Trunnion axles may have up to 30,000 pounds per axle if the trunnion configuration has two axles, eight tires per axle, the axles are at least 10-feet wide and there is at least five feet of spacing between the axles, but not more than six feet.
Travel on load-restricted roads requires that the axle and axle group weights be load-zoned. Load-zoned weight is 10% less than the maximum permitted. For example, load-zoned weight on a tandem is 41,400 pounds.
Vehicles and loads with axle, axle group and gross weight that exceed these limits may qualify for a Super Heavy permit.TxDMV issues a single-trip super heavy permit for the movement of non-divisible vehicles and/or loads that exceed 254,300 pounds total gross weight, the maximum permit weights on any axle or axle group or between 200,001 pounds and 254,300 pounds with less than 95 feet of axle spacing.Single-trip permits may only be used for one movement, during the times specified on the permit, from a specific point of origin to a specific destination.
