The maximum width of a commercial truck is eight feet, six inches or 102 inches. If a truck exceeds this width, it may be restricted to public roads that can account for its larger size. The width limit applies only to the structure of the truck and does not include mirrors or safety devices. Additionally, the height of a commercial truck is limited to 13 feet, six inches.Length Limits
The general length limitation for commercial trucks is 50 feet. However, a semitrailer when operated in a commercial tractor-semitrailer combination can have a length up to 53 feet.Ohio Weight Law
