There are two opposing forces when it comes to delivering freight. On one hand, shippers want to be able to move as much freight as possible in a single load. On the other hand, roads and bridges can be damaged and sometimes collapse when they are subjected to too much weight. To manage ever increasing freight demands as well as costly infrastructure repairs, federal and provincial governments have implemented a system of weight and size restrictions for commercial vehicles. Knowing the weight and dimensions of your vehicle, your cargo and even your fuel is important to stay in compliance as you drive.
