1 . If the safety relief valve in the air brake system releases air:

The compressor needs more air.

The air pressure has become too high.

The brakes are fully operational.

An air brake system has a safety relief valve, which releases air from the tanks if the pressure gets too high. If the valve must operate, something in the system is wrong and should be addressed by a mechanic.

2 . A low air pressure warning signal should activate:

When tank pressure falls below 120 psi.

When tank pressure falls below 60 psi.

When tank pressure falls below 10 psi.

In an air brake system, a low air pressure warning signal must come on if air pressure in the tanks falls below 60 psi. This warning signal may come in the form of a light, a buzzer, or a wig wag.

3 . If one-fourth of the leaves in a leaf spring are missing when a vehicle is inspected:

The vehicle’s driver will be allowed to drive, but only at reduced speeds.

The vehicle will be put out-of-service until it is fixed.

The vehicle will be fine to drive since most of the spring is in place.

When inspecting a vehicle's suspension, you should look for broken or missing leaves in the leaf springs. Any defect of this kind is dangerous. If one-fourth or more of the leaves are missing from any leaf spring, the vehicle must be put out-of-service.

4 . When starting from a stop:

A vehicle should shift to the right.

A vehicle should be put into third gear.

A vehicle should not roll back.

To avoid hitting anything behind you, make sure that your vehicle does not roll back when you start from a complete stop.

5 . Which of the following is the best advice for driving in fog?

Try not to drive in fog.

Use your high beam headlights.

Turn off your lights.

Driving in fog is always dangerous and should be avoided entirely if at all possible. If you must drive in fog, be sure to turn on your low beam headlights and fog lights, even during the daytime.

6 . Before driving a vehicle with air brakes, you should ensure that the ____ come on automatically when air pressure falls below 45 psi.

Spring brakes

Parking brakes

Air brakes

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 levels drop to an unsafe level, the parking brake valve should pop out and spring brakes should come on.

7 . To prevent your vehicle from rolling backward when beginning to move, you can:

Partly engage the clutch before taking your foot off the brake pedal.

Place the vehicle in second gear.

Use the parking brake when stopping.

To ensure that your vehicle does not roll backward when beginning to move after a stop, you should partly engage the clutch before removing your right foot from the brake pedal.
