Number of Question 20

Passing Score 16

1. 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.

2. The center of gravity in a trailer should be:

As high as possible.

As low as possible.

At the rear of the trailer.

The weight of cargo in a vehicle should be distributed as low as possible. Having a center of gravity that is too high will increase the risk of a rollover.

3. Pre-trip inspections should be done:

Differently each time in order to place emphasis on different items.

The same way each time to prevent you from forgetting anything.

Once in a while.

A pre-trip inspection should be completed in the same way before every drive. Consistency will help you learn all of the proper steps and decrease the likelihood that you will forget to check something.

4. On flat surfaces, wheel chocks:

Can be used to prevent a parked vehicle from moving.

Make it easier for a parked vehicle to roll.

Should only be used on the front driver's side tire.

In situations where a driver cannot use a parking brake, wheel chocks can be used to hold a parked vehicle in place on a level surface.

5. A posted speed limit for cars:

Is usually safe for buses.

May be too fast for buses.

May be too slow for buses.

Particularly on curves, the maximum posted speed limit may be safe to be driven in a car but too fast to be driven in a bus. Be especially careful when the road has been made slippery by rain or snow.

6. How much distance will an air brake-equipped vehicle need to come to a complete stop if it is traveling at 55 mph under ideal driving conditions?

300 feet

100 feet

450 feet

A vehicle's total stopping distance is made up of perception distance, reaction distance, brake lag distance, and braking distance. With all of these factors included, an air brake-equipped vehicle traveling at a speed of 55 mph under ideal driving conditions will need approximately 450 feet to come to a complete stop.

7. What kind of brakes do most newer heavy-duty trucks use?

Single air brakes

Dual air brakes

Triple air brakes

Most newer heavy-duty vehicles use dual air brake systems. A dual air brake system has two separate air brake systems which use a single set of brake controls.
