What is the best way to reduce the chance of hydroplaning on a rain-covered road?
Correct answer: Reduce speed so the tires have a better chance to maintain contact with the pavement.
Water can separate tires from the road. Lower speed is a basic precaution; sudden control changes and close following increase the danger.

Water covers the road ahead, but it looks shallow. What is the safer decision?
Correct answer: Turn around and find another route rather than enter the flooded road.
Floodwater can cause you to lose control or stall the engine. Do not enter a flooded roadway just because the water looks shallow.

The main pavement looks clear, but the temperature is near freezing. Why should you be cautious on bridges and shaded areas?
Correct answer: Bridges and shaded areas can be icy when the rest of the road is clear.
Bridges and shady spots freeze first and can remain icy after other pavement clears. Reduce speed and avoid abrupt steering or braking.

After a minor collision with no injuries, both vehicles can be moved safely but are blocking traffic. What does the manual direct?
Correct answer: Move them off the road, then handle the required exchange and reporting.
For a minor noninjury crash, move safely out of traffic when the vehicles are movable. Moving them does not end the drivers' duties to exchange information and report as required.
