1 . Dual tires should:

When inspecting a vehicle, you should verify that your dual tires do not come into contact with one another, or with any other part of the vehicle.

2 . Front wheel braking works:

Under most conditions. Front wheel braking is effective under all road conditions. It is unlikely that you will experience a front wheel skid, even on ice.

3 . Having weight loaded in a way that creates a high center of gravity:

Transporting cargo that is loaded with a high center of gravity increases the risk that the transporting vehicle will tip over. Cargo should be loaded with a safe weight distribution.

4 . An Anti-Lock Braking System (ABS) will:

Not decrease your stopping distance. Anti-Lock Braking Systems (ABS) will help you to maintain control during hard braking. ABS will not necessarily shorten your stopping distance.

5 . The maximum amount of play that is safe on a 20-inch steering wheel is:

A steering wheel with play of more than 10 degrees may be defective. On a 20-inch wheel, this is equal to about two inches of movement at the rim of the wheel.

6 . When driving down a steep grade, your brakes may fade. What happens if brakes fade?

They work differently from front to back. If you use your brakes too much when traveling on a steep downgrade, they may overheat and become less effective. To avoid causing your brakes to overheat on a steep hill, you should rely on engine braking.

7 . A safety valve is set to open at ____ pounds per square inch (psi).

The safety valve protects air tanks and the rest of an air brake system from accumulating too much air pressure. The safety valve is usually set to open at 150 psi.
