Warning, Construction & Information SignsStandalone practice
On a 55 mph highway, you see this sign: a yellow diamond with a black box that holds red, yellow and green lights. A curve blocks your view of the road ahead. What should you do?
Correct answer: Be ready to slow down and stop, because a traffic signal is ahead.
Why
Signals on high-speed roads often come after a curve or a hill, where you see them late. Take your foot off the gas early, so you can stop smoothly if the light is yellow or red. A smooth, early stop also warns the drivers behind you.
