What should a driver check when approaching an underpass with low clearance?

When approaching an underpass with low clearance, checking for signage indicating the height is crucial. This signage provides essential information regarding the maximum vehicle height that can safely pass through the underpass without risk of collision or damage. Tall vehicles must take particular care, as failing to heed this information can result in serious accidents, injuries, or damage to the vehicle and infrastructure.

Height clearance signs are typically placed well in advance of the underpass to give drivers ample opportunity to make alternate routes if necessary. Understanding the importance of this signage reinforces safe driving practices, particularly for drivers of larger vehicles such as trucks and buses, which may exceed the height limits of certain underpasses. By prioritizing this check, drivers can ensure their safety and that of others on the roadway.
