Number of Question 20

Passing Score 16

1. To avoid becoming an aggressive driver, you should:

Plan trips without allocating extra time for traffic.

Tailgate.

Drive slowly in the left lane.

Not make gestures to other drivers.

To avoid becoming an aggressive driver, begin a trip with realistic expectations of how long the trip will take, allowing extra time for traffic delays. Do not tailgate other vehicles. To avoid upsetting other drivers, do not drive slowly in the left lane and do not gesture at the drivers (even in seemingly minor ways, like shaking your head).

2. If colors are being used to distinguish glad hands, which color is used for emergency lines?

Orange

Yellow

Blue

Red

When trailer air lines are color-coded, the service lines are generally blue and the emergency lines are generally red.

3. As part of the vehicle inspection test, you will be asked to:

Explain what you would inspect and why.

Replace an electrical fuse.

Unload the trailer.

During the vehicle inspection test, you will be required to do a complete inspection of your vehicle. During this inspection, you must explain to the examiner what you are inspecting and why you are inspecting those items.

4. A stopped bus:

Is not a cause for concern since it is stopped.

Is only a concern if passengers are exiting the bus.

Is a concern whether or not passengers are visible.

You should always exercise caution when driving near a stopped bus. There could be passengers in the vicinity and the bus may either prevent them from seeing you or you from seeing them.

5. If you identify a large box in your lane on the road ahead, you should:

Slow down.

Speed up.

Not be worried because another vehicle will likely hit it before your vehicle.

Swerve into another lane of traffic.

Slow down and be very careful if you see foreign objects in your lane. Remember that even something that seems relatively light and harmless, like a cardboard box, could contain harder or heavier items that could cause damage to your vehicle.

6. What can the “crack-the-whip” effect do?

Turn over trailers.

Make loud noises.

Make trucks accelerate.

Make trucks decelerate.

The "crack-the-whip" effect can cause a trailer to turn over during a lane change. To avoid this phenomenon, drivers should make lane changes at slow, safe speeds.

7. Traction is important in:

Safe braking.

Properly using turn signals.

Operating the horn.

You will not be able to brake or steer your vehicle without adequate traction. Ensure that your tires are in proper working condition before beginning a trip.
