Warning, Construction & Information SignsStandalone practice
You drive a rented moving truck that is 13 feet tall. Before an underpass, you see this yellow sign with arrows above and below the height 12'-6". What should you do?

Correct answer: Stop and use another route, since the truck is taller than the clearance
Why
Know the height of your vehicle and its load before you drive a tall truck, a trailer, or a car with cargo on the roof. A strike can damage the vehicle and the structure and can hurt people. Plan your route before the trip, so that you do not have to stop or back up near the underpass.
