Weight Restriction Statutes
There are two main weight restriction statutes that are vehicle specific. That means the weight restriction is tied to the vehicle, not the roadway. This can be a complex distinction, but one that has to be grasped to be able to defend overweight violations in Texas. The statutes and their formulas are for violations related to a vehicle being overweight compared to it’s registered or legal allowable weight. those statutes are as follows:
Sec. 621.101. MAXIMUM WEIGHT OF VEHICLE OR COMBINATION.
(a) A vehicle or combination of vehicles may not be operated over or on a public highway or at a port-of-entry between Texas and the United Mexican States if the vehicle or combination has:
(1) a single axle weight heavier than 20,000 pounds, including all enforcement tolerances;
(2) a tandem axle weight heavier than 34,000 pounds, including all enforcement tolerances;
(3) an overall gross weight on a group of two or more consecutive axles heavier than the weight computed using the following formula and rounding the result to the nearest 500 pounds:
W = 500((LN/(N – 1)) + 12N + 36)
Sec. 621.102. AUTHORITY TO SET MAXIMUM WEIGHTS.
(a) The executive director of the Texas Department of Transportation may set the maximum single axle weight, tandem axle weight, or gross weight of a vehicle, or maximum single axle weight, tandem axle weight, or gross weight of a combination of vehicles and loads, that may be moved over a state highway or a farm or ranch road if the executive director finds that heavier maximum weight would rapidly deteriorate or destroy the road or a bridge or culvert along the road. A maximum weight set under this subsection may not exceed the maximum set by statute for that weight.
As a general rule, your typical 18 wheeler tractor trailer is going to max out at a gross weight of about 80,000 pounds. Depending on the type of commercial vehicle, the gross weight and tandem axle weight can vary greatly, so it is important to refer to the specific statute that your commercial vehicle is governed by in order to evaluate specific weight applied.
