The weight and size limitations for road freight can vary by country and region. In the United States, for example, the maximum weight allowed on most federal highways is 80,000 pounds

Regulations governing road freight can also vary by country and region. In the United States, the Federal Motor Carrier Safety Administration (FMCSA) is responsible for regulating commercial motor vehicle operations, including safety requirements for drivers, vehicles, and carriers. Other countries may have their own regulatory agencies or follow international standards such as those set by the International Road Transport Union (IRU).
