An axle weight limit is the maximum legal amount of weight that can be placed on a single axle or group of axles of a vehicle. These limits are set to protect roads, bridges, and public infrastructure from damage caused by heavy or unevenly loaded vehicles. An axle weight limit ensures that each part of a heavy vehicle is within safe loading limits, helping prevent road damage and ensuring safe handling.
