Passing Score 16

1. What tells you how much pressure is in your vehicle's air tanks?

The supply pressure gauge

The ABS malfunction lamp

The tractor protection valve

A vehicle that is equipped with air brakes must also be equipped with a supply pressure gauge. This gauge tells the driver how much air pressure is in each of the vehicle's air tanks.

2. If you realize you may be running late to your destination, you should:

Speed up.

Get upset.

Deal with it and drive at a safe speed.

To reduce the risk of developing aggressive driving behavior, you should take measures to manage your stress. One strategy to do this is to simply take a deep breath and accept your circumstances if you realize you will be late to your destination.

3. When traction is poor, a driver should accelerate especially slowly:

Because it is always good to accelerate slowly.

To keep from losing control of the vehicle.

To keep from accelerating faster than the vehicle ahead.

You should accelerate very gradually when driving under slippery conditions. Using too much power in such conditions may cause you to lose control of your vehicle.

4. When loading a trailer, the heaviest cargo should be placed:

On top of the lightest parts of the cargo.

Under the lightest parts of the cargo.

At the rear of the trailer.

It is important that vehicles are not top-heavy, if at all possible. A top-heavy vehicle is at an increased risk of rollover. Place the heaviest pieces of cargo underneath lighter pieces of cargo.

5. ABS allows a driver to:

Drive faster.

Maintain control of their vehicle while braking.

See farther ahead of their vehicle.

The purpose of an Anti-Lock Braking System (ABS) is to help prevent wheel lockup and help a driver maintain control of their vehicle when braking on a slippery surface.

6. The tire load:

Can be exceeded in cooler conditions.

Is the maximum safe weight a tire can carry at a given pressure.

Must be written in the shipping papers.

Tire load is the maximum weight a tire can safely carry at a given pressure. This rating is stated on the side of each tire.

7. When using a fire extinguisher to put out a fire, you should:

Stay as far away as possible from the flames.

Aim at the flames.

Use any extinguisher on every type of fire.

Stay as far away from a fire as possible and aim your fire extinguisher at the source or base of the fire, not at the flames. It may be appropriate to extinguish certain fires with water. If you are unsure of how to treat a specific fire, you should wait for trained firefighters to arrive.
