What should you do if driving a commercial vehicle over 13 feet in height and unsure about clearance?

When driving a commercial vehicle that exceeds 13 feet in height and encountering uncertainty about clearance, the safest and most responsible action is to stop and check for clearance. This approach helps to prevent accidents or damages that could result from colliding with structures such as bridges, overpasses, or power lines that may not accommodate your vehicle's height.

Stopping allows you to assess the situation accurately—whether that involves getting out of the vehicle to look for signs indicating clearance heights or using a GPS or mapping tool that provides information about height restrictions along the route. By verifying clearance before proceeding, you protect not only your vehicle but also others on the road from potential hazards associated with misjudging overhead space.

Continuing to drive without knowledge of the clearance can lead to significant risks, including damaging the vehicle, causing road blockages, or even injuries. Checking ensures that you make informed decisions based on accurate information rather than an assumption that could have serious consequences.
