3 / 50
A. When you use a helper, they should use a clear spoken signal
B. It is safer to back toward the right side of the vehicle than toward the driver's side
C. You should avoid backing whenever you can
Because you cannot see everything behind your vehicle, backing is always dangerous. Avoid backing whenever you can. When you have to back, here are a few simple safety rules: Start in the proper position, look at your path, use mirrors on both sides, back slowly, back and turn toward the driver's side whenever possible, and use a helper with clear hand signals whenever possible.
4 / 50

Most vehicles now have an ABS light on the instrument panel that will light up briefly when the vehicle is started to alert you that the vehicle has ABS, you can check to see if the vehicle was built on or after March 1, 1998, or you can check for wires from your brakes.
7 / 50
A. go straight ahead even if the steering wheel is turned.

A. You need to be in the same gear at the bottom of the hill.
B. You will not be able to shift into a lower gear once you are going down a hill.
C. The clutch is made to be used on even surfaces.
Do not try to downshift after your speed has already built up. You will not be able to shift into a lower gear. You may not even be able to get back into any gear and all engine braking effect will be lost.
11 / 50
A. turn on your parking lights.
B. watch for sharp pavement drop-offs.
C. reduce speed only if workers are close to the roadway.
When people are working on the road, it is a hazard. There may be narrower lanes, sharp turns, or uneven surfaces.
12 / 50

17 / 50
A. Only occurs when there is a lot of water
B. Cannot occur when driving through a puddle
C. Is more likely if tire pressure is low
D. Only occurs at speeds above 50 mph
Hydroplaning is more likely if tire pressure is low, or the tread is worn. The grooves in a tire carry away the water; if they aren't deep, they don't work well.
18 / 50
A. Increase speed going downhill
B. No answers are correct
C. Tip over
D. Increase stopping distance
The height of the vehicle's center of gravity is very important for safe handling. A high center of gravity means you are more likely to tip over. It is most dangerous in curves, or if you have to swerve to avoid a hazard.

26 / 50
A. the engine warm.
B. the engine oil flowing.

A. Open the windows for some fresh air.
B. Drink a cup of coffee.
C. Drink energy drinks.

34 / 50
A. Use the parking or emergency brake.
B. Pump the brakes.
C. Shift up.
When the system won't build up pressure here are some things you can do: downshift, pump the Brakes, use the parking brake, and find an Escape Route.
35 / 50
A. The lighter your vehicle, the less trouble you will have with the wind
B. Winds are especially a problem when coming out of tunnels
C. You should drive alongside other vehicles to help break up the wind
Strong winds make it difficult to stay in your lane. The problem is usually worse for lighter vehicles. This problem can be especially bad coming out of tunnels.
36 / 50
A. Stay off the brake until the vehicle slows down on its own
B. Quickly steer onto the shoulder
C. Begin controlled or stab braking
D. Begin light braking
It's natural to want to brake in an emergency, however, braking when a tire has failed could cause loss of control. Once the vehicle has slowed down brake very gently, pull off the road, and stop.

Because you cannot see everything behind your vehicle, backing is always dangerous. Avoid backing whenever you can. When you have to back, here are a few simple safety rules: Start in the proper position, look at your path, use mirrors on both sides, back slowly, back and turn toward the driver's side whenever possible, and use a helper with clear hand signals whenever possible.
40 / 50
A. The drinker clearly sees how alcohol is affecting them

C. The effects of alcohol decreases
D. The drinker can sober up in less time
Accident statistics show that the chance of a crash is much greater for drivers who have been drinking than for drivers who have not.
41 / 50
A. Slow down gradually
B. Use a smaller following distance
C. All the above
D. Apply the brakes during turns
I It will take longer to stop, and it will be harder to turn without skidding, when the road is slippery. Wet roads can double stopping distance at any speed, reduce speed, and slow down gradually on a wet road.
42 / 50
A. One year
B. Four years
C. Two years
A DOT physical exam is valid for up to 24 months. The medical examiner may also issue a medical examiner's certificate for less than 24 months when it is desirable to monitor a condition, such as high blood pressure.

Inspect the cargo and its securing devices within the first 50 miles after beginning a trip. Make any adjustments needed.
44 / 50
A. Steer into the left lane
B. Steer into the oncoming lanes
C. Steer to the right
If the shoulder is clear, going right may be best. No one is likely to be driving on the shoulder, but someone may be passing you on the left. You will know if you have been using your mirrors. If you are blocked on both sides, a move to the right may be best. At least you won't force anyone into an opposing traffic lane and a possible head-on collision.
45 / 50
A. Get the vehicle off the road and stop in an open area
B. Immediately open the door and jump out
C. Head for the nearest service station
The first step is to get the vehicle off the road and stop. In doing so: park in an open area, away from buildings, trees, brush, other vehicles, or anything that might catch fire. Don't pull into a service station!
46 / 50
A. Apply the brakes while turning
B. Steer with one hand so that you can turn the wheel more quickly
C. Don't turn any more than is needed to clear what is in your way

47 / 50
A. Stop and turn your vehicle around before entering the road
B. Make sure the road is clear, and continue to return to the road

50 / 50
A. Take your foot off the accelerator
B. Try a lower gear
C. Take your foot off the accelerator and apply the brakes
Skids caused by acceleration usually happen on ice or snow. Taking your foot off the accelerator can easily stop them. If it is very slippery, push the clutch in. Otherwise, the engine can keep the wheels from rolling freely and regaining traction.
