1 . When driving a bobtail tractor, you should be aware that:

Bobtails stop very easily.

Bobtails cannot drive as fast as tractors with semitrailers.

Bobtails are more difficult to stop than tractors with semitrailers.

Bobtails are illegal in most states.

Bobtail tractors are tractors that are not attached to any semitrailers. When operating a bobtail, you should be aware that stopping can be difficult and that it will take a longer distance to bring the bobtail to a complete stop than it would a tractor attached to a loaded semitrailer.

2 . If you cannot reverse your trailer in a straight path, you should:

Swerve back and forth while backing.

Back toward the driver's side.

Back toward the passenger's side.

If you need to back your trailer but cannot back up in a straight path, you should back on a curved path toward the driver's side of the vehicle. This will allow you the best possible visibility while backing.

3 . What is a tractor protection valve?

A valve to keep air in the brake system should there be a bad leak

A valve that prevents a truck from being stolen

A valve that prevents the driver from driving too fast

A tractor protection valve keeps air in a tractor or truck air brake system should the trailer break away or develop a bad leak. The valve will close automatically if the pressure drops to an unsafe level.

4 . One way to prevent a rollover is to:

Move cargo to the left side of the rig.

Keep cargo centered on the rig.

Move cargo to the right side of the rig.

Keep cargo as far from the ground as possible.

A rollover is more likely if cargo is unevenly loaded in a rig. To help prevent a dangerous rollover, it is important to keep a load as centered on the rig as possible.

5 . If a trailer begins to jackknife, you should not:

Release the brakes.

Apply the trailer hand brake.

Allow the wheels to grip the road.

Allow the trailer to straighten out.

If a trailer begins to jackknife, you should release the brakes and allow the trailer wheels to regain traction with the road. Do not apply the trailer hand brake to attempt to straighten out the rig because it will only prolong the skid. The application of brakes is what caused the wheels to lock in the first place.

6 . To help prevent a rollover, cargo should be:

Placed as high as possible inside a trailer.

Placed as low as possible inside a trailer.

Placed on the driver’s side of a trailer.

If a vehicle is top-heavy, it is more likely to roll over. The weight of cargo should be positioned as low in a trailer as possible to minimize this risk.

7 . Driving a combination vehicle ____ than driving a single vehicle.

Is easier

Requires more driving skill

Is better for training

Is safer in inclement weather

Driving a combination vehicle usually requires more skill than driving a single vehicle. Combination vehicles are generally longer and heavier than single commercial vehicles.
