1. An air compressor governor will stop the compressor from pumping air once the air tanks have an air pressure level of:

125 psi.

100 psi.

150 psi.

80 psi.

An air compressor governor will stop the compressor from pumping air once the air tanks are at an air pressure level of 125 psi. This air pressure level is referred to as the "cut-out" level.

2. On a leaf spring, the leaves:

May be broken.

Are not required.

Should not be broken.

Should shift.

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.

3. During a basic vehicle control skills test, you may be asked to:

Alley dock.

Parallel park to your right.

Parallel park to your left.

All of the above.

Maneuvers that may be included in the basic vehicle control skills test include straight line backing, offset back/right parking, offset back/left parking, driver side parallel parking, conventional parallel parking, and alley docking.

4. When it is difficult for others to see your vehicle, such as at dawn or dusk, you can help other drivers by:

Keeping your lights off.

Turning your lights on.

Driving on the shoulder.

Waving an arm out the window.

At times when visibility is low, you should turn your headlights on to the low beam setting. If you are having a difficult time seeing others, they are probably having a difficult time seeing you.

5. Eating while driving is:

A good way to save time.

A dangerous activity.

Acceptable if you are eating foods that are easy to eat.

Smoking, eating, or drinking are distracting activities and should be avoided while you are driving. Instead, plan ahead and allow yourself time to stop to eat when making a lengthy trip.

6. If the brakes “pull” to one side or the other when you use them, it's a sign that:

The brakes are working properly.

The brakes need to be checked.

The brakes are new.

The brakes have too much stopping power.

If your vehicle "pulls" to one side when braking, you may have brake trouble. If there is an issue with your brakes, you should fix the issue before driving. Operating an unsafe vehicle is against federal and state laws.

7. When traveling in heavy traffic, the safest driving speed is:

The posted speed limit.

The speed of surrounding traffic.

A speed much slower than the flow of surrounding traffic.

In heavy traffic, it is safest to match the speed of surrounding vehicles. Vehicles traveling in the same direction at the same speed are unlikely to collide. However, you should not exceed legal speed limits.
