Not enough to pass :-(

Ouch! While you were on a roll there for a few questions, you didn’t pass this time. But I know this test, and I think you’ll pass next time. Really.

1. When braking with ABS, you should:
Push the brake pedal harder than usual.
Push the brake pedal as you normally would.
Push the brake pedal more lightly than usual.

When operating a vehicle with an Anti-Lock Braking System (ABS), you should apply your brakes in the same manner as you would if operating a vehicle without ABS.

2. Keeping cargo centered on a rig can:
Help you drive faster.
Prevent a rollover.
Make turns more dangerous.

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.

3. When backing with a trailer, turning toward the driver’s side is encouraged because:
The driver will have the best possible view.
Power lines should be on the passenger's side.
Other drivers can offer assistance on the passenger's side.

When driving in reverse, it is always recommended that a driver backs their vehicle toward its left side. This will allow the driver the best possible view of the rear of their vehicle.

4. When traveling down a steep downgrade:
The air brakes should be used.
The vehicle should be placed in a low gear and the driver should use engine braking.
The driver should continually downshift instead of using the brakes.

On long and/or steep downgrades, you should primarily use engine braking to control the speed of your vehicle. Use your brakes only as a supplement to this effect.

5. Anti-Lock Braking Systems (ABS):
Reduce a vehicle's normal braking capacity.
Are in addition to other braking systems and do not reduce a vehicle's braking power.
Are not effective on larger vehicles.

If equipped, ABS is in addition to a vehicle's normal braking system and does not increase or decrease the braking power of any other system. ABS only activates when a vehicle's wheels are about to lock.

6. What is removed when an air tank is drained?
Water and oil
Liquid cleaners

In an air brake system, air tanks have drains to remove accumulations of water and compressor oil. Allowing water and oil to accumulate in the system could cause damage to the brakes.

7. If you remain in neutral for too long while switching gears:
The vehicle will speed up.
You may have trouble putting the vehicle into the next gear.
You may kill the engine.

If you remain in neutral for too long while switching gears, you may have difficulty putting the vehicle into the next gear. If this happens, do not try to force the gear shift. Instead, return to neutral, release the clutch, increase the engine speed to match the road speed, and try again.

8. When attaching more than one semi-trailer to your tractor, you should place:
The lightest semi-trailer at the very end of the combination.
The heaviest semi-trailer at the very end of the combination.
Any trailer in any position in the combination.

The semi-trailer with the heaviest load should be secured in the first position behind a tractor. The trailer with the lightest load should be positioned in the rear of a combination.

9. Eating while driving is:
A good way to save time.
A dangerous activity.
Acceptable if you are eating foods that are easy to eat.

Smoking, eating, or drinking are distracting activities and should be avoided while you are driving. Instead, plan ahead and allow yourself time to stop to eat when making a lengthy trip.

10. If you have an engine fire, you should:
Open the hood as soon as possible.
Turn off the engine as soon as possible.
Not use a fire extinguisher.

To keep an engine fire from spreading, you should turn off the vehicle's engine as soon as possible. Do not open the hood if you don't have to.

11. When leaving your vehicle unattended:
The parking brake should be used.
The parking brake only needs to be used if the vehicle is parked on a slope.
The parking brake should not be used, as it can damage the tires.

In general, you should always use the parking brake when parking your vehicle. However, you should not apply the parking brake if your brakes are very hot or if your brakes are wet and temperatures are below freezing.

12. Shut-off valves:
Prevent air from escaping air brake systems.
Prevent air from entering air brake systems.
Override vehicles that are out of control.

Shut-off valves are used in air supply lines to control the passage of air from one trailer to another. The rear shut-off valve should always be closed to prevent air from leaving the braking system.

13. A driver should use the trailer hand valve to:
Uncouple the trailers.
Test the trailer brakes.
Apply the emergency brakes.

Using a trailer hand valve while driving could create a skid. The trailer hand valve should only be used when testing the trailer brakes.

14. When traveling on a downgrade, your vehicle will:
Slow down.
Travel at the same rate as on level roadway.
Speed up.

Gravity causes a vehicle's speed to increase when traveling on a downgrade. Adjust your speed before reaching a downgrade.

15. Drivers trapped behind a slow-moving vehicle often:
Follow the vehicle too closely.
Allow the vehicle plenty of space.
Are happy with the speed of travel.

It is common for drivers to tailgate slow-moving vehicles that cannot keep up with the speed of surrounding traffic. If you are being tailgated, allow the other driver to pass your vehicle.

16. An after-trip inspection should be done:
Once a week.
Once a month.
After every trip.

You should always complete an after-trip inspection of your vehicle at the end of a trip, day, or tour of duty. Complete a vehicle inspection report, if required.

17. If confronted by an aggressive driver, you should:
Make eye contact to better communicate with them.
Ignore their gestures.
Not move out of their path of travel.

If confronted by an aggressive driver, it is most important to get out of their way, if possible. Do not make eye contact with the driver, as doing so could provoke them. Do not let them provoke you with their actions.

18. In a dual air brake system:
Air tanks are shared between both systems.
Each system has its own air tanks.
You must designate which system you are using.

There are two air brake systems in a dual air brake system. The systems share a set of brake controls, but each system has its own tanks, hoses, and lines.

19. If an air compressor is belt-driven, the belt should be routinely checked to ensure that it is:
Properly tightened.

If your vehicle has air brakes, the air compressor drive belt should be checked before each drive. Check the tightness of the belt and verify that it is in good condition.

20. An empty truck:
Requires a shorter stopping distance than a full truck.
Requires a longer stopping distance than a full truck.
Takes the same distance to stop as a full truck.

Empty trucks require longer stopping distances than full trucks because they have less traction available.
