Road Rules for the Height of Tractor Trailers
OTR trucks deliver products to and from manufacturers, warehouses, and retailers across the United States, and they must be aware of various regulations, as well as the size of their rig and any limiting factors, such as low bridges.
Clearly Marked Height
Every overhead bridge has a roadside sign clearly announcing the bridge height, and the trailer’s height is visible in the rear view mirror at the driver’s eye level.
Federal Height Regulations
The height of existing bridges serves to limit the height of trucks and trailers that can safely pass beneath them; according to the US National Highway Traffic Safety Administration, a semi-rig and its trailer must be lower in height than the bridge clearance in order to pass under a bridge.
State Height Regulations
Most states limit commercial semi rigs to a height of 13 feet, 6 inches, though some states, such as Florida’s for car-carrying vehicles, allow a vehicle’s height to reach 14 feet. States issue local regulations to protect commercial OTR drivers.
Low Clearance Bridges
If an OTR semi driver fails to recognize a low bridge hazard, it can result in serious injury to the truck driver, cargo, and the highway bridge.
