Number of Question 20

Passing Score 16

1. What is a wig wag?

A type of warning system

A tube used to move air from the compressor to the tanks

A noise made by air brakes when used

A part within the braking unit that allows air to move freely

A wig wag is a type of low air pressure warning device in an air brake system. It drops a mechanical arm into the driver's view when the air pressure in the tanks falls below 60 psi.

2. Both systems in a dual air brake systems share:

Air tanks.

Hoses.

Air lines.

An air compressor.

Both systems in a dual air brake system share a single air compressor. If the air compressor is damaged, neither system will be able to operate properly.

3. Brake fade is a result of:

Exposure to sunlight.

Exposure to moisture.

Excessive use.

Not using the brakes enough.

If brakes are used too much, they will overheat and become less effective. This is referred to as brake fade.

4. Spring brakes come on:

When too much air pressure is lost.

When a control on the dashboard is activated.

When the tires have minimal tread depth.

When the brakes are noisy.

Spring brakes come on automatically when air pressure drops to an unsafe psi level. Instead of waiting for the spring brakes to automatically activate, you should safely exit the road as soon as you notice the low pressure warning signal and bring your vehicle to a stop while you are still able to control the brakes.

5. Fueling with passengers on board:

Is encouraged during long trips.

Should only be done if absolutely necessary.

Is not a concern as long as the passengers stay inside the bus.

Should be done to show the passengers that there is enough fuel to get to the next stop.

You should not refuel a bus while passengers are on board, unless it is absolutely necessary to do so. In particular, never refuel a bus carrying passengers while inside an enclosed building.

6. A driver should always:

Stay in the right lane.

Have an emergency plan.

Stay in the left lane.

Drive faster than the posted speed limit.

While driving, you should continually scan the road to spot potential hazards in advance. Make emergency plans for how to deal with the hazards if they become dangerous.
