1 . To lower the risk of a rollover, you should:

Load the cargo as far forward as possible.

Load the cargo as far back as possible.

Load the cargo as low as possible.

Stack the cargo as high as possible.

To lower the risk of a rollover, load your cargo as closely to the ground as possible. To further reduce this risk, take curves and corners slowly.

2 . A loss of air pressure in the emergency line will cause:

The suspension springs to extend.

The tractor protection valve to open.

The rear trailer to detach from the combination.

The emergency brakes to activate.

The emergency air line controls the emergency brakes on a combination vehicle. A loss of air pressure in the emergency line will cause the emergency trailer brakes to activate.

3 . Combination vehicles:

Are usually shorter than single commercial vehicles.

Are usually lighter than single commercial vehicles.

Require more skill to drive than single commercial vehicles.

Are easier to drive than single commercial vehicles.

Combination vehicles are usually heavier and longer than single commercial vehicles. For these reasons, they usually require more driving skill than single commercial vehicles.

One air line.

Two air lines.

Three air lines.

Four air lines.

Combination vehicles have two air lines: a service line and an emergency line.

5 . In a double or triple combination:

Cargo weight must be evenly distributed between all trailers.

The heaviest trailer should be positioned directly behind the cab.

The heaviest trailer should be positioned in the rear.

The weight of the trailers does not matter.

When positioning trailers in a combination, the most heavily-loaded trailer should be the closest to the tractor. The lightest trailer should be positioned in the rear.

6 . Using the trailer hand brake while experiencing a trailer jackknife will:

Stop the skid.

Straighten the trailer.

Increase traction.

Continue the skid.

If you are experiencing a trailer jackknife, you can help your tires regain traction by releasing the brakes. Using a trailer hand brake while experiencing a skid will only cause the skid to continue.

7 . Simply changing lanes can cause:

A “crack-the-whip” effect, resulting in a rollover.

A trailer to straighten out.

Confusion over which lane the driver is hoping to use.

Other drivers to reduce their speed.

Due to the "crack-the-whip" effect caused by rearward amplification, changing lanes too quickly in a combination vehicle can result in a rollover.
