1 . Before driving a vehicle with air brakes, you should ensure that the spring brakes come on automatically when:

Air pressure falls below 45 psi.

Air pressure falls below 20 psi.

Driving downhill.

Driving uphill.

Before driving a vehicle with air brakes, you should ensure that the spring brakes come on automatically when air tank pressure falls to a level between 20 and 45 psi. You can do this by chocking the wheels and releasing air from the braking system by stepping on and off the brake pedal. Once the pressure drops to an unsafe level, the parking brake valve should pop out and spring brakes should come on.

2 . If the Anti-Lock Braking System (ABS) is malfunctioning:

You will not have any brakes.

You will still have brakes.

You should only use the parking brake to stop.

You should stop driving and wait for the ABS to work again.

An Anti-Lock Braking System (ABS) is in place as an addition to a braking system. It intervenes to prevent brakes from locking up during hard braking. If ABS is not working, the basic braking functions on a vehicle will still remain, so the driver can continue to drive and brake normally.

3 . Pre-trip inspections should be done:

Differently each time, emphasizing different items.

The same way each time so you are less likely to forget something.

Once in a while.

By someone other than the driver.

Pre-trip inspections should be conducted in the same way every time. This will reinforce the steps, making it less likely that you will forget to inspect something important.

4 . Mirrors should be adjusted:

While moving.

When the trailers are straight.

When you are standing next to the vehicle.

By an assistant.

Mirrors should be checked prior to the beginning of a trip. On a vehicle with a trailer, mirror adjustment can only be checked accurately if the connected trailer is straight.

5 . When backing, a helper:

Should be used whenever possible.

Often adds to the confusion of backing.

Should only be used if the driver is not feeling confident.

Would likely get in the way.

Backing up is always dangerous because you cannot see everything behind your vehicle. Whenever possible, use a helper who can monitor your blind spots.

6 . If you must drive a school bus during periods of high winds, you should:

Loosen your grip on the steering wheel.

Increase your speed.

Reduce your speed.

Drive normally.

You should slow down when driving a school bus in high winds. Keep a strong grip on the steering wheel and try to anticipate gusts.

7 . Pressing and releasing the brake pedal unnecessarily can:

Release air faster than it can be replaced.

Add more air to a brake system.

Make the brake pedal harder to depress.

Create a loud noise.

On a vehicle with air brakes, pressing and releasing the brake pedal unnecessarily may let air out of the braking system faster than the compressor can replace it. This may cause the system's air pressure to become too low and the brakes to stop working.
