1 . If oil and water build up in your vehicle's air tanks, the brakes:

May not work correctly.

May feel squishy.

Will squeal loudly when used.

Will be extremely sensitive.

Air tanks should be drained daily to remove water and oil buildup. An excess of oil and water in the air tanks can interfere with proper brake function.

2 . If an Anti-Lock Braking System (ABS) is equipped on a trailer but not on a tractor:

The truck should not be driven because ABS needs to be on both the tractor and trailer.

The truck should be driven more slowly than usual.

The tractor should not be used and a new tractor with ABS should be located.

The tractor and trailer can still be used together.

A vehicle being equipped with anti-lock brakes on only the tractor or only the trailer provides additional control during braking.

3 . While driving, if it is discovered a vehicle's ABS is not working, the driver should:

Put on their hazard lights.

Downshift.

Brake normally.

Use their parking brake to stop.

If an Anti-Lock Braking System (ABS) is not working, the vehicle's basic braking functions are still intact. The driver should continue to drive and brake in a normal fashion.

4 . The minimum size of placards identifying hazardous materials is:

Four inches.

Six and one-quarter inches.

Nine and three-quarter inches.

10 and three-quarter inches.

Hazardous materials placards must be at least 10 and three-quarter inches square.

5 . To correct a drive-wheel braking skid, a driver should do all of the following, except:

Remove your foot from the brake pedal.

Turn quickly in the direction of the skid.

Countersteer after the vehicle is back on course.

Accelerate.

To correct a drive-wheel braking skid, you should first remove your foot from the brake pedal to allow the locked wheels to begin rolling again. Quickly steer in the direction you want to go, then countersteer to prevent your vehicle from skidding in the opposite direction.

6 . When inspecting a tank, a driver should:

Follow their instincts.

Refer to their specific vehicle’s operator manual.

Look online for information about the vehicle.

Make sure there is no rust on the outside of the tank.

Because there are many different types of tanks, each of which with its own specific features, a driver should always consult the operator's manual for information on how to inspect a particular tank.
