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 turning, when should the turn signal be canceled?
Before entering the turn
During the turn
After the turn is completed

Always signal continuously through a turn. Do not cancel a signal until the turn is finished.

2. If your brakes fail on a downgrade, your best hope to stop is to:
Use an escape ramp.
Use the shoulder.
Drift to a stop.

If your brakes fail on a downgrade, you will have to look outside your vehicle for a way to stop. Using an escape ramp is the safest way to stop your vehicle.

3. When taking the basic vehicle control skills test, failing to exit your vehicle properly during any exercise will result in:
Failure of only that exercise.
An extra point against your final score.
Automatic failure of the basic vehicle control skills test.

When exiting your vehicle during the basic vehicle control skills test, you must face the vehicle and maintain three points of contact at all times. If your testing vehicle is a bus, you must maintain contact with the handrail. Exiting the vehicle incorrectly may result in automatic failure of the basic control skills test.

4. If you are confronted by an aggressive driver, you should:
Make eye contact.
Ignore their gestures.
Try to race.

If you encounter an aggressive driver, you should not let yourself be provoked by any angry gestures they make toward you. Avoid making eye contact with the other driver and do not try to race them.

5. One way to avoid becoming an aggressive driver is to:
Talk on your cell phone while driving.
Question others' driving abilities.
Set realistic expectations regarding travel time.

To help avoid frustration, which can lead to aggressive driving behavior, you should begin a trip with realistic expectations about your travel time. Plan ahead to allow time for potential traffic delays. Other strategies to help prevent aggressive driving behavior include driving an appropriate speed and keeping a reasonable following distance; avoiding making gestures at other drivers; and keeping your hands on the steering wheel.

6. Why should you regularly drain the air tanks?
Because the air gets old and needs to be replaced
Because compressed air contains some water and the water collects in the tanks
To allow for a change in pressure

Compressed air usually contains a certain amount of moisture and compressor oil, which can build up in the air storage tanks and damage the brake system. The tanks should be drained to clean out these accumulations. On a tank with a manual drain valve, draining should be performed at the end of each day of driving.

7. Some air brake systems introduce alcohol into the system to:
Make the brakes work without squeaking.
Prevent ice from forming in the brake system.
Prevent people from breathing the air from the system.

Some air brake systems contain an alcohol evaporator. An evaporator introduces alcohol into the system to help inhibit the formation of ice in cold weather.

8. Belts in the engine compartment should:
Be frayed.
Not have excessive wear.
Be greasy.

When inspecting your vehicle's engine, check the belts for tightness and excessive wear. The amount of "give" that is safe for each belt in a given engine will vary, so learn what is appropriate for your vehicle.

9. Bracing is used to:
Make items stand taller in a trailer.
Prevent items from moving in a trailer.
Make it easier to unload items from a trailer.

Blocking and bracing are used to prevent cargo from shifting in transit. Blocking is used in the front, in the back, and on the sides of a piece of cargo to prevent movement. Bracing prevents movement by reaching from the upper portion of a piece of cargo to the floor and sides of the cargo compartment.

10. If a vehicle is power steering-equipped, the hoses should be:
Checked for leaks.
Securely connected to the battery.
Carrying fuel.

When inspecting a vehicle equipped with power steering, you should inspect the hoses, pumps, and fluid levels. Specifically check the hoses for leaks.

11. By beginning a left turn before reaching the center of an intersection, you:
Will likely complete the turn satisfactorily.
May hit other vehicles with the left side of your vehicle.
Can expect other drivers to move their vehicles to accommodate your turn.

When planning to turn left at an intersection, make sure you have reached the center of the intersection before beginning the turn. If you turn too soon, off-tracking may cause the left side of your vehicle to hit another vehicle.

12. If you are taking the driving test and the route does not include a railroad crossing, you:
Will not have to do anything related to a crossing.
May have to explain how you would cross railroad tracks.
Will have to take a different route.

During the on-road driving test, if your route does not include a railroad crossing, the examiner may ask you to explain and demonstrate the necessary procedures at a simulated location.

13. What is the Gross Vehicle Weight Rating (GVWR)?
The weight stated by the manufacturer as the loaded weight of a single vehicle
The maximum weight that can be pulled by a vehicle
The minimum weight that can be hauled by a vehicle

A Gross Vehicle Weight Rating (GVWR) is the value specified by the manufacturer as the loaded weight of a single vehicle.

14. If mirrors are dirty before starting a trip:
They will likely become clean after driving a short distance.
It should not be a concern.
They should be cleaned before the vehicle is driven.

During a pre-trip inspection, be sure to check the mirrors and windshield for dirt and anything else that could interfere with your ability to see. Clean them as necessary.

15. Water that has collected on a roadway can cause:

The risk of hydroplaning begins when water has collected on the surface of a road.

16. Which of the following is not part of a vehicle’s air brake system?
Air gauges
Low pressure warning device
Air filter

Components of an air brake system include an air compressor, an air compressor governor, air storage tanks, air tank drains, an alcohol evaporator, a safety valve, a brake pedal, foundation brakes, supply pressure gauges, an application pressure gauge, a low air pressure warning signal, a stop light switch, a front brake limiting valve (on some older vehicles), spring brakes, and parking brake controls.

17. One way to prevent hydroplaning on wet road surfaces is to:
Ensure that your tires have good tread depth.
Under-inflate your tires.
Drive faster than usual.

When driving on a wet road surface, the risk of hydroplaning is increased if your tire pressure is too low or your tire tread is too worn. If you begin to hydroplane, release the accelerator and push in the clutch to slow down.

18. Roads are especially slippery right after it begins to rain because:
The water mixes with oil and grease on the road.
Tires are not made to drive in wet weather.
The water yet hasn't absorbed the dirt and grease.

Roads are often especially slippery when it first begins to rain. Rainwater forms a slick film when mixed with oil and grease on the road surface that has not yet washed away.

19. Rust around wheel nuts may mean:
It rained recently.
The nuts are loose.
The nuts are too tight.

It is important to inspect your tires before every drive. Rust around wheel nuts may indicate that they are loose.

20. Of the following, which is not a recommended way to spot potential signs of trouble?
Watching the gauges
Using your senses
Checking critical items only at the beginning and end of a trip

During a trip, you should regularly make checks to ensure that your vehicle is operating properly. Check the instrument panel and gauges; look at your mirrors; and examine the tires, cargo, and lights. Use all of your senses and be alert for anything that could be an early indication of trouble.

21. When trying to put out an electrical fire, you should:
Use water.
Use a B:C extinguisher.
Use an X extinguisher.

B:C fire extinguishers are designed to work on electrical fires and burning liquids. Don't pour water on an electrical fire.

22. Cargo being transported should be checked:
Only before the trip.
Before the trip and again within the first 50 miles of the trip.
Only by the loading personnel.

Cargo should be inspected before beginning a trip, within the first 50 miles of the trip, and every three hours or 150 miles traveled thereafter. Cargo should be inspected every time the driver stops to take a break. The driver of a truck transporting cargo is responsible for the cargo being safely secured throughout the trip.

23. When backing with a trailer:
You should not back up in a straight line.
You should not correct drift until you are far off course.
You should frequently pull forward to reposition the vehicle.

When backing, you should pull forward to reposition your vehicle whenever needed. Drift should be corrected immediately by turning the steering wheel in the direction of the drift.

24. You may be an aggressive driver if you:
Expect delays on your drive.
Slow down and maintain a reasonable following distance.
Make hand gestures that could anger other drivers.

Avoid being an aggressive driver by being realistic about your travel time, making allowance for delays, maintaining reasonable following distances, and not making hand gestures that could anger another driver.

25. When traveling down a downgrade, the speed of a vehicle will likely:
Stay the same.

The force of gravity will cause a vehicle's speed to increase when traveling downhill.

26. When loading a trailer, it is important to:
Place as little weight as possible over the axles.
Place an appropriate amount of weight over the axles.
Not be concerned with how the cargo's weight is distributed.

When loading cargo, it is important that the weight placed on each axle is neither too little nor too much. Inappropriate loading can interfere with steering, create inadequate wheel traction, or damage the axles.

27. Which of the following is not a sign of tire failure?
A loud sound
Smoother steering

If you experience tire failure, you may hear the loud "bang" sound of a blowout or feel a heavy thumping or vibration in your vehicle. If steering begins to feel heavy, or if the rear of your vehicle begins to fishtail, you should stop to check your tires.

28. Which of the following is not a sign of fatigue?
Difficulty focusing, with frequent blinking
Yawning repeatedly or rubbing eyes
Staying in your lane

Potential warning signs of fatigue include difficulty focusing, frequent blinking, or heavy eyelids; yawning repeatedly or rubbing your eyes; daydreaming; wandering or disconnected thoughts; trouble remembering the last few miles you've driven; missing exits or traffic signs; having trouble keeping your head up; drifting from your lane; following too closely; hitting a shoulder rumble strip; or feeling restless and irritable.

29. 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.

30. You should test the low pressure warning signal by:
Turning on the engine and applying the trailer hand brake.
Rapidly pressing and releasing the brake pedal.
Removing wheel chocks and disengaging the parking brake.

It is essential that your low pressure warning light functions properly. After allowing the system to charge, you can test the warning signal by rapidly applying and releasing the brake pedal. This will release air from the braking system and the warning signal should come on when pressure drops to a dangerous level.

31. When making tight maneuvers, it is important for a driver to:
Open their door for a better look.
Use their mirrors.
Flash their headlights.

While regular mirror checks should always be part of your driving routine, you should make a particular point of checking the mirrors when changing lanes, turning, merging, or making tight maneuvers.

32. How should you brake if your vehicle's ABS is not working?
Brake normally, as you will still have functioning brakes.
Pump the brake repeatedly.
Press the brake pedal down as hard as you can.

Without a working Anti-Lock Braking System (ABS), your vehicle will still have normal brake function. Continue to drive and brake as you normally would and have your ABS serviced as soon as possible.

33. When starting from a complete stop, a vehicle should:
Jerk forward.
Roll backwards.
Not move backwards.

To avoid hitting vehicles behind you, you must ensure that your vehicle will not roll backward when you start moving forward from a stopped position.

34. Which of the following is not a type of distraction?

Distractions that can affect safe driving can be classified as physical (such as reaching for an object), mental (such as talking with passenger), or both (such as talking on a hand-held phone).

35. A truck should be parked:
So that it must be backed up to leave the space.
So that it can be pulled forward to leave the space.
On the grass.

Because you can't see everything behind you, backing is always dangerous and should be avoided whenever possible. Choose parking spaces from which you can pull forward when you leave.
