1 . After finishing a pre-trip inspection, you should:

Close the service line valve.

Remove the service line valve.

Leave the emergency line valve open.

Leave the rear shut-off valves open.

Before a trip, you should ensure that air reaches all air brakes on all trailers by opening up the rear emergency line and service line shut-off valves to listen for escaping air. Close both shut-off valves before beginning to drive.

2 . Proper coupling technique:

Is the same on all vehicles.

Is essential to the safe operation of a vehicle.

Includes ensuring that the fifth wheel plate is not greased.

Can be learned over time.

Knowing proper coupling and uncoupling technique is fundamental to the safe operation of combination vehicles. Improper coupling can be very dangerous.

3 . A lightly-loaded combination vehicle will stop more slowly than a fully-loaded vehicle because:

The stiff suspension springs and strong brakes will have high traction.

The stiff suspension springs and strong brakes will have low traction.

The brakes only operate when a trailer reaches a minimum weight.

The suspension springs only operate when a trailer reaches a minimum weight.

An empty combination vehicle will come to a complete stop more slowly than a fully-loaded vehicle. The stiff suspension springs and strong brakes will have lower traction on a light trailer than they would if the vehicle carried more weight.

4 . Which type of vehicle is most prone to the “crack-the-whip” effect?

A five-axle tractor semi-trailer

A three-axle tractor semi-trailer

A bobtail tractor

A triple trailer

Triple combination trailers are most vulnerable to the "crack-the-whip" effect.

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 . Older trailers are not equipped with spring brakes. This means that if the air supply for a vehicle's air braking system leaks away:

The trailer will stop normally.

The trailer will not have brakes.

The trailer will speed up.

Older trailers do not have spring brakes. This means that if the air supply in an older trailer's air tank has leaked away, there will be no working brakes connected to the trailer and its wheels will turn freely.

7 . To prevent a rollover, a driver should:

Keep cargo low.

Place cargo high.

Keep cargo loose.

Turn quickly.

Rollovers can happen when a combination vehicle is turned too quickly. To help prevent the risk of rollover, it is important to keep the vehicle's center of gravity low by loading cargo as close to the ground as possible.
