1 . Multi-speed axles and auxiliary transmissions are used:

To make a vehicle run more smoothly.

To provide extra gears.

To get improved gas mileage.

On many vehicles, multi-speed rear axles and auxiliary transmissions are used to provide extra gears. They are usually controlled by a selector knob on the gearshift lever.

2 . Air brakes use ____ to function.

Compressed air

Liquid air

Nitrogen

Air brakes function through the use of compressed air.

3 . A low air pressure warning signal should activate:

When tank pressure falls below 120 psi.

When tank pressure falls below 55 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 55 psi. This warning signal may come in the form of a light, a buzzer, or a wig wag.

4 . Which of the following is not an example of a distracted person that motorists should be worried about?

A driver talking to a passenger in their vehicle

A child on the side of the road

A construction worker on the side of the road

A person sitting on a bench waiting for a bus

You should be cautious when you are near people who are not paying attention to the road. Be wary of drivers who are engaged in conversation with passengers, children near the road, and road workers.

5 . It is illegal to operate a CMV with a minimum blood alcohol content (BAC) of:

0.01 percent.

0.02 percent.

0.04 percent.

0.08 percent.

Operating a CMV with a minimum blood alcohol content (BAC) of 0.04 percent is illegal and will result in loss of license for at least one year for a first offense. If you operate a CMV with any detectable amount of alcohol in your system while remaining below the legal limit of 0.04 percent, you will be put out-of-service for at least 24 hours.

6 . You should not use the parking brake:

If your vehicle is stopped on a level surface.

If your vehicle is stopped on a slight incline.

If your vehicle's brakes are very hot.

If your vehicle's other braking systems seem to be working adequately.

A parking brake should not be used if the vehicle's brakes are very hot from use on a steep downgrade or if the brakes are very wet and temperatures are freezing. Using the parking brake when brakes are hot could cause damage to the brakes, and using the brakes when they are wet in freezing weather may cause the brakes to ice up, rendering the vehicle immobile.

7 . If you are being tailgated, you should:

Drive on the shoulder.

Pull off the roadway.

Drive faster.

Allow the vehicle to pass.

If you are being tailgated, it is best to allow more room to open up in front of your vehicle. This will help you avoid the need for sudden stops, which could result in the tailgater rear-ending you, and will make it easier for the tailgater to pass. Speeding up may only make things more dangerous by prompting the other driver to continue tailgating you at a higher speed.
