Truck drivers must be aware of overhead clearances at all times. 1. A driver cannot rely just on posted clearances; you must know the height of the equipment and/or load in order to know if there is sufficient clearance. If a clearance is doubtful, stop in a safe place and check before proceeding. Overhead clearances can be reduced by resurfacing the roadway, accumulation of ice and snow, crown/hill of the roadway, and/or uneven surface of the road.
