Number of Question 20

Passing Score 16

1. Having ABS on only one axle:

Can be dangerous.

Still allows you additional control when braking.

Slows the vehicle, but cannot stop it.

If you have an Anti-Lock Braking System (ABS) equipped on only the tractor, only the trailer, or only one axle, you will still have more control over the vehicle when braking than you would without ABS. You should brake normally.

2. When arriving at a destination, it is best to remind exiting passengers to take their carry-on bags with them:

Before you stop the bus.

After you stop the bus.

At least five times.

As they exit the bus.

Before a bus is brought to a complete stop at its destination, it is best for the driver to remind exiting passengers to take their carry-ons with them.

3. Dry bulk tanks require special care because:

They have low centers of gravity.

They have high centers of gravity.

Loads are usually stable.

They are usually overloaded.

Driving with a dry bulk tank requires special care, both because dry bulk tanks have high centers of gravity and because their loads often shift in transit. Be especially careful when taking turns and curves while operating such a vehicle.

4. What happens if the air pressure in a system's air tanks falls below 60 psi?

A warning light will come on.

The vehicle will not shift out of gear.

The front lights will flash.

The vehicle should stop.

In an air brake system, a low pressure warning signal should activate if the pressure in the air tanks falls to a level below 60 psi. This signal may be in the form of a warning light or a wig wag.

5. A tank endorsement is:

Only required when transporting gases.

Only required when transporting liquids.

Used when transporting both liquids and gases.

Optional when transporting hazardous materials.

In general, a tank endorsement is required to a drive tank vehicle used to transport liquids or gases. This applies to both hazardous and non-hazardous materials.

6. When a brake pedal is pressed and the S-cam is turned, the S-cam:

Presses the brake shoes against the inside of the brake drum.

Tightens the brake drum onto the axle.

Presses the brake lining against the wheel.

Releases air from the air tanks.

When a brake pedal is pressed and the S-cam is turned, the S-cam presses the brake shoes against the inside of the brake drum. This causes friction and will cause the vehicle to slow.

7. A dual air brake system:

Consists of two separate air brake systems that share a single set of controls.

Is a single air brake system with two different sets of controls.

Consists of one air brake system for the left side of the truck and one system for the right side of the truck, each with its own set of controls.

A dual air brake system is made up of two separate air brake systems. The systems share a single set of brake controls, but each has its own air tanks, hoses, and lines. One system typically operates the regular brakes on the rear axle or axles while the other system operates the regular brakes on the front axle.
