Questions & Answers.
1. You should use low beams whenever you can. True or False? - CORRECT ANSWER False.
Use High Beams When You Can. Some drivers make the mistake of always using low beams. This
seriously cuts down on their ability to see ahead. Use high beams when it is safe and legal to do so. Use
them when you are not within 500 feet of an approaching vehicle.
2. What should you do before you drive if you are drowsy? - CORRECT ANSWER If you are drowsy, sleep
before you drive! Even a nap can save your life or the lives of others.
3. What effects can wet brakes cause? How can you avoid these problems? - CORRECT ANSWER When
driving in heavy rain or deep standing water, your brakes will get wet. Water in the brakes can cause the
brakes to be weak, to apply unevenly, or to grab. This can cause lack of braking power, wheel lockups,
pulling to one side or the other, and jackknife if you pull a trailer. Avoid driving through deep puddles or
flowing water if possible. If not, you should: Slow down and place transmission in a low gear. Gently put
on the brakes. This presses linings against brake drums or discs and keeps mud, silt, sand, and water
from getting in. Increase engine rpm and cross the water while keeping light pressure on the brakes.
When out of the water, maintain light pressure on the brakes for a short distance to heat them up and
dry them out. Make a test stop when safe to do so. Check behind to make sure no one is following, then
apply the brakes to be sure they work well. If not, dry them out further as described above. (CAUTION:
Do not apply too much brake pressure and accelerator at the same time, or you can overheat brake
drums and linings.)
4. You should let air out of hot tires so the pressure goes back to normal. True or False? - CORRECT
ANSWER False.
Air pressure increases with temperature. Do not let air out or the pressure will be too low when the tires
cool off. If a tire is too hot to touch, remain stopped until the tire cools off. Otherwise the tire may blow
out or catch fire.
5. You can safely remove the radiator cap as long as the engine isn't overheated. True or False? -
CORRECT ANSWER True.
