What is the main concern when crossing a bridge with a commercial vehicle?

The main concern when crossing a bridge with a commercial vehicle is the weight limit of the bridge. Bridges are constructed with specific load-bearing capacities, which are clearly marked with weight limits. Exceeding this limit can cause structural damage to the bridge or, in worst-case scenarios, lead to a collapse. It is critical for drivers of commercial vehicles to be aware of these limits to ensure both their safety and the integrity of the bridge structure.

While the vehicle's height and the condition of the road surface are indeed important factors for safe driving, they do not relate specifically to the structural limitations imposed by bridges. The number of lanes available is also not a factor that affects the safety or operational compliance of crossing a bridge. Therefore, understanding and adhering to the weight limits is paramount for commercial vehicle operators when crossing bridges.
