Passing Score 40

1. Talking on a hands-free phone while driving:

Does not distract the driver.

Only distracts the driver if the driver is speaking.

Can be distracting to the driver.

While speaking on a hands-free phone while driving is less dangerous than speaking on a hand-held phone, it is just as likely to mentally distract a driver. Simply engaging in conversation takes their mental focus away from the task of driving.

2. When backing with a trailer, you should begin by:

Turning the steering wheel in the direction of the turn.

Turning the steering wheel in the direction opposite of the turn.

Turning the wheel as sharply as possible.

When backing with a trailer, begin by turning the steering wheel in the direction opposite of the turn. Once the trailer starts to turn, reverse the direction of the steering wheel to follow the trailer.

3. During an applied leakage test, what is the maximum leakage rate that is safe for a single vehicle with air brakes?

10 psi in one minute

5 psi in one minute

3 psi in one minute

It is important to know the maximum air loss rate that is safe for your specific vehicle. A single vehicle with air brakes should have a leakage rate no higher than 3 psi in a minute during an applied leakage test.

4. When traveling long distances, you should:

Take rest breaks.

Drive as fast as possible.

Drive through the night.

To avoid becoming fatigued on a long trip, you should take a break after every 100 miles or two hours of driving. Driving through the night, or during any other time when you would normally be asleep, raises the danger of fatigue.

5. When pulled over to the side of the road, you should:

Rely on your taillights to alert other motorists to your presence.

Not worry about other motorists.

Use your four-way emergency flashers to alert other motorists to your presence.

When stopped on the side of the road, be sure to turn on your vehicle's four-way emergency flashers, especially during times of lowered visibility. Place warning devices within 10 minutes of being stopped.

6. A second conviction of operating a CMV with a minimum blood alcohol concentration (BAC) of 0.04 percent will result in:

The loss of your CDL for life.

The loss of your CDL for five years.

The loss of your CDL for one year.

It is illegal to operate a CMV if your blood alcohol concentration (BAC) is 0.04 percent or higher. A first offense will result in the loss of your CDL for one year. A second offense will result in the loss of your CDL for life.
