Heavy rain has flooded a dip in the road ahead. The water looks only a few inches deep, and there is no barricade. What should you do?
A approaches water covering both lanes of the road. The card states that rain has flooded a dip, the water looks shallow and no barricade is posted; the submerged pavement is hidden.
Correct answer: Turn around and use another route, because the water can stall or float a car.
Why
About six inches of water reaches the bottom of most passenger cars and can cause a loss of control or a stall. About two feet of moving water can sweep away most vehicles, even SUVs and pickups. If no other route is open, move to higher ground and wait for the water to go down.
