For trucks and heavy vehicles, what is the speed limit in relation to light vehicles?

Trucks and heavy vehicles have specific speed limits that are set lower than those of light vehicles to account for their larger size, weight, and longer stopping distances. This is important for safety, as heavier vehicles require more time and distance to react and stop compared to lighter ones. Therefore, the law establishes a speed limit that is typically 10 mph below the limit set for light vehicles. This regulation helps reduce the risk of accidents and ensures that all vehicles can navigate roadways safely, especially in areas with high traffic or complex conditions.
