1 . What do anti-lock brakes do?

Help a driver avoid wheel lockup

Lock up the front wheels

Prevent a vehicle from accelerating while traveling uphill

The function of an Anti-Lock Braking System (ABS) is to prevent the vehicle's wheels from locking up from hard brake application.

2 . In cold weather, an alcohol evaporator should be checked and filled:

Once a week.

Every day.

Every hour.

Once a month.

An alcohol evaporator can help prevent ice from building up in an air brake system. In cold weather, the evaporator should be checked and refilled every day.

3 . Which of the following is not acceptable emergency equipment?

Three red reflective triangles

Six fuses

Three liquid burning flares

Four yellow squares

During the vehicle inspection test, you will need to show emergency equipment, including spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and a properly charged and rated fire extinguisher.

4 . A vehicle should be equipped with all of the following, except:

A fire extinguisher.

Spare electrical fuses.

Warning devices for parked vehicles, such as flares.

5 . What can happen if the air pressure gets too low in an air brake system?

The brakes may squeak.

The brakes may not work.

The brakes may be sluggish.

The posted weight limit.

The color of a sign you just passed.

Presses the brake shoes against the inside of the brake drum.

Tightens the brake drum onto the axle.

Presses the brake lining against the wheel.

Releases air from the air tanks.

When a brake pedal is pressed and the S-cam is turned, the S-cam presses the brake shoes against the inside of the brake drum. This causes friction and will cause the vehicle to slow.
