1 . During the driving test, when encountering a railroad crossing, you should:

Pass another vehicle on the tracks if the other vehicle is going too slow.

Get out of the vehicle to check for a train.

Not change gears while your vehicle is on the tracks.

During the on-road driving test, do not stop, change gears, pass another vehicle, or change lanes while any part of your vehicle is in a railroad crossing.

2 . If a vehicle's Anti-Lock Braking System (ABS) is malfunctioning:

The vehicle will have no brakes.

The vehicle will still be able to brake.

The vehicle will likely travel faster than usual.

An Anti-Lock Braking System (ABS) intervenes to reduce brake pressure if there is a risk of wheel lockup. If the ABS isn't working, the vehicle's basic braking functions are not affected. A driver should continue to drive and brake in a normal manner.

3 . To ensure that you do not slow down traffic when driving a large truck, you should:

Switch gears while driving uphill.

Try to pass another vehicle while driving uphill.

Stay in the right lane whenever possible.

If a heavy load prevents your vehicle from keeping up with the speed of other traffic, you should stay in the right lane.

4 . If you are confronted with an aggressive driver, you should:

Make eye contact.

Try to stay in their way.

Ignore any hand gestures.

The best thing to do when confronted with an aggressive driver is to get out of their way, if possible. Avoid making eye contact, which could further provoke the driver. Ignore any hand gestures made by the driver.

5 . What should happen before the air pressure in an air brake system tank falls below 55 psi?

The warning light should activate.

The vehicle will be unable to shift out of gear.

The front lights should flash.

The low air pressure warning signal must activate before the air supply pressure drops below 55 psi in the air tank. If the warning signal does not turn on when being tested during an inspection, the vehicle is not safe to drive.

6 . When alley docking, you should first:

Position your vehicle directly in front of the alley.

Back up directly in front of the alley.

Stop parallel to the outer boundary of the alley.

If you are asked to alley dock, you should first pull past the alley and stop your vehicle in a position that is parallel to the outer boundary. From there, you should back your vehicle entirely into the alley parking area. Your vehicle should be parked in a straight position within the boundaries of the parking space.

7 . The weight of a truck:

Usually has no impact on stopping distance.

Is a major factor affecting stopping distance.

Is not as important as the type of cargo in determining stopping distance.

A vehicle's weight is an important factor affecting its stopping distance. The heavier a vehicle is, the more work the brakes will need to do to bring it to a complete stop.
