The maximum distance a load can extend beyond the bed of a truck, commonly referred to as an "overhang," is subject to regulations that vary by jurisdiction. These regulations are in place to ensure safety on the roads and prevent hazards caused by improperly secured or excessively protruding loads.
In the United States, for example, the Federal Motor Carrier Safety Administration (FMCSA) has regulations regarding commercial vehicle overhangs. According to FMCSA regulations, the maximum overhang allowed beyond the bed of a truck is 3 feet (91.44 centimeters) in front of the front bumper and no more than 4 feet (121.92 centimeters) beyond the rear of the vehicle.
However, it's imperative to note that these regulations can differ between states. They may apply differently to different types of vehicles, such as commercial trucks, trailers, or recreational vehicles. Additionally, local regulations and ordinances may impose further restrictions or requirements. Therefore, it is crucial to consult the specific laws and regulations of the jurisdiction where the truck will be operating. This will ensure compliance with the maximum overhang limits.
