U.S. truck weight reference
Truck weight rules, explained with official sources.
Start with the federal framework, learn how scale tickets relate to axle groups, and use state pages to verify limits, permits, and fine structures against government sources.
The federal baseline comes from FHWA bridge formula and federal size and weight regulations; state pages link to the agency source used for every populated field.
