Warning, Construction & Information SignsStandalone practice
You drive at 55 mph, which is the posted limit, and you pass this sign. It shows a speed that is lower than 55 mph. What should you do?

Correct answer: Prepare to slow so that you are at the lower speed when you reach the new speed limit sign
Why
Speed limits often drop where a highway enters a town, a school area or a work zone. The warning lets you slow gradually and signal to the drivers behind you with your brake lights. The new limit applies from the speed limit sign, and the basic speed rule can require an even lower speed.
