Big and slow vehicles behave differently from cars, and workers along the road need protection. Give trucks space, be patient behind farm equipment, and move over or slow down for any vehicle stopped with its lights flashing.

Know the rule

Trucks are not large cars. Most fatal crashes between a heavy vehicle and other vehicles are caused by the passenger vehicle, according to NHTSA statistics.
