Number of Question 50

Passing Score 40

1. Which of the following is not an indication of damaged brakes?

Cracked drums

Shoes with oil or grease on them

Shoes worn thinly

Pads free of oil or grease

Potential problems to check for when inspecting brakes include cracked drums; shoes or pads with oil, grease, or brake fluid on them; and shoes that are missing, broken, or worn dangerously thin.

2. Which of the following is not a sign of a person being drowsy?

Frequent blinking

Drifting from your lane

Feeling hungry

Yawning

Driving drowsy is dangerous and should always be avoided. Warning signs of drowsiness include frequent blinking, your eyes closing or going out of focus by themselves, frequent yawning, and drifting between lanes.

3. Having weight loaded in a way that creates a high center of gravity:

Increases the likelihood of a rollover.

Increases the likelihood that items will fall down.

Increases the difficulty of unloading the cargo.

Transporting cargo that is loaded with a high center of gravity increases the risk that the transporting vehicle will tip over. Cargo should be loaded with a safe weight distribution.

4. During a walk-around inspection, ensure there are no cracks on the brake drums that are more than ____ of the width of the friction area.

One half

One quarter

One third

One tenth

Before beginning a trip, it is important to check the brake drums during your walk-around inspection. It is unsafe to drive if any brake drum has a crack more than one half of the width of the friction area.

5. Texting while driving is worrisome:

Because it creates both mental and physical distractions.

Because a message may be upsetting to the driver.

Because the texts may be more interesting than the task of driving.

Because it is less efficient than a phone call.

When driving, texting is a particularly dangerous distraction because it distracts a driver both mentally and physically.

6. Hanging meat in a refrigerated truck:

Is a good way for inexperienced drivers to gain experience.

Requires a skilled driver.

Is illegal in most states.

An operator should drive with care when transporting a cargo of hanging meat. Such a load is unstable, both because it has a high center of gravity and because the swinging of the meat can affect the driver's handling of the vehicle.

7. ABS allows you to:

Drive faster.

Brake harder.

Stay in control when stopping.

The function of an Anti-Lock Braking System (ABS) is to help prevent wheel lockup during hard braking. With ABS equipped on your vehicle, you should drive and brake in the same manner that you would without it.
