Being properly rested is essential to the safe operation of a CMV. To maintain alertness, most people need eight to nine hours of sleep per night.

5 . Which of the following determines your blood alcohol concentration (BAC)?

How much you drink

How frequently you drink

The temperature of the drink

The color of the drink

The three main factors that determine a person's blood alcohol concentration (BAC) are how much alcohol was consumed; how fast it was consumed; and the person's body weight. The only thing that can lower a person's BAC is waiting for the alcohol to leave their system naturally.

6 . In very hot weather, tires should be checked regularly because:

They may melt.

Air pressure may increase with the temperature.

The tread wears down extra quickly.

The lug nuts may loosen.

Air expands as it gets warmer, so the air pressure in your tires could reach dangerously high levels while being used in very hot weather. If this happens, stop and let your tires cool. Do not let air out of the tires, as this could result in the pressure dropping to an unsafe level once the tires cool down.

7 . When backing with a trailer, you should:

First turn the steering wheel in the direction of the turn.

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

Turn the wheel as sharply as possible.

Not use the brakes.

When backing a straight truck, you would turn the wheel in the direction you want to go. By contrast, when backing a vehicle with a trailer, you must turn the steering wheel in the direction opposite of where you want to go. Once your trailer starts to turn, you should turn the steering wheel the other way to follow the trailer.
