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. Who is responsible for the safe operation of a vehicle?
The driver
The mechanic
The owner

The person driving a vehicle is responsible for its safe operation. Be sure to perform routine vehicle inspections before operating a commercial motor vehicle.

2. When driving, it is important to:
Avoid using your mirrors while in heavy traffic.
Look only to the front and right side of the vehicle.
Look to the front, sides, and rear of the vehicle.

It is essential that you are aware of what is happening on all sides of your vehicle at all times. Scan the road ahead and make regular checks of the mirrors on both sides of your vehicle while you are driving.

3. When backing with a trailer:
You should not back up in a straight line.
You should not correct drift until you are very far off course.
You should pull up to reposition the vehicle as needed.
You should avoid braking.

When backing with a trailer, you should pull up to reposition your vehicle as needed.

4. Driving at night is:
Safer than driving during the day.
Just as safe as driving during the day.
More dangerous than driving during the day.

Driving at night is more dangerous than driving during the day. It is more difficult for drivers to see hazards, the glare of headlights can affect drivers' vision, and there are more fatigued and impaired drivers on the road.

5. 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.

6. What is axle weight?
The weight transmitted to the ground by one axle
The weight of one axle
How much weight an axle can hold

"Axle weight" refers to the weight transmitted to the ground by one axle or one set of axles.

7. A jogger wearing a stereo headset:
Is probably aware of what is happening around them.
May not be aware of what is happening around them.
Can hear the sounds of traffic.

Be careful around pedestrians, joggers, and cyclists who are wearing headphones. They may be unable to hear your vehicle approaching and may do dangerous things because they do not know you are there.

8. Which of the following is not an example of a distracted person who should concern motorists?
A driver talking to a passenger in their vehicle
A person sitting on a bench waiting for a bus
A construction worker on the side of the road

You should be cautious when you are near people who are not paying attention to the road. Drivers and pedestrians who are talking to someone may be distracted by the conversation and not fully paying attention to the road. Workers on or near the road may not be paying attention to traffic because they are focused on their work, and can themselves also be a distraction to drivers.

9. When checking power steering hoses during a pre-trip inspection, you should look for:
Secure connections to the battery.
Extra hose pieces available for repairs.

When doing a pre-trip inspection on a vehicle with power steering, be sure to check the hoses, pumps, and fluid level. In particular, you should check the hoses for leaks.

10. Hanging meat:
Should never be transported by trailer.
Can be an unstable load.
Must be approved by the Environmental Protection Agency (EPA).

An operator should drive with care when transporting a cargo of hanging meat. Such a load is unstable, both because it has a high center of gravity and because the swinging of the meat can affect the driver's handling of the vehicle.

11. What does an Anti-Lock Braking System (ABS) do?
Allow the rear wheels to lock up
Allow all wheels to lock up
Help prevent wheel lockup
Alert other motorists when you are braking

The purpose of an Anti-Lock Braking System (ABS) is to prevent a vehicle's wheels from locking up when the driver brakes hard on a slippery surface.

12. Stopping distance can be affected by:
Time of day.

Factors that can affect your vehicle's stopping distance include driving speed, the vehicle's weight, and the slipperiness of the road surface.

13. 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.

14. If braking at a speed of 55 mph while driving on dry pavement, the brake lag can add ____ to your vehicle's total stopping distance.
32 feet
15 feet
50 feet
10 feet

The total stopping distance for vehicles equipped with air brakes is made up of four factors: perception distance, reaction distance, brake lag distance, and braking distance. When braking at a speed of 55 mph while driving on dry pavement, the brake lag can add around 32 feet to a vehicle's total stopping distance.

15. When the brake pedal is pushed down, air brakes work:
After a short delay.
After about a minute.
Only if it is warm outside.

Because air takes time to flow through the air lines to the brakes, air brakes cannot begin working instantly. There is often a brake lag of at least one-half of a second between the moment the brake pedal is pressed and the moment the brakes begin to work.

16. What is a wig wag?
A type of warning system
A tube used to move air from the compressor to the tanks
A noise made by air brakes when used
A part within the braking unit that allows air to move freely

A wig wag is a type of low air pressure warning device in an air brake system. It drops a mechanical arm into the driver's view when the air pressure in the tanks falls below 60 psi.

17. What kind of force do emergency brakes use?
Air pressure

Air brakes are really three different braking systems: the service brake, the parking brake, and the emergency brake. Emergency and parking brakes are applied with mechanical force.

18. What should be done before transporting an over-length load?
Special transit permits should be acquired.
Fire departments along the route should be alerted.
Tolls should be paid.

Over-length, over-width, and/or overweight loads may require special permits from the Department of Transportation.

19. If you are unsure if there is enough space for your vehicle to safely pass under an upcoming bridge, you should:
Increase your speed.
Swerve as you pass under the bridge.
Slow down.

21. A stopped bus:
Is not a cause for concern.
Is not a concern if passengers are not unloading.
Should not be on the roadway.
Is a concern, whether passengers are visible or not.

Always drive cautiously around a stopped bus. Passengers may cross in front of or behind it, and the bus may prevent them from seeing your vehicle.

22. Failing to exit your vehicle properly during an exercise in the basic vehicle control skills test will result in:
Failure of only that exercise.
A reset of that exercise.
Automatic failure of the basic vehicle control skills test.
An extra point against your score.

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.

23. What is a danger of rolling back when you start to accelerate?
The transmission may be damaged.
The truck is not made to go backwards.
You may hit a vehicle behind you.
You may lose your position in traffic.

To avoid hitting someone or something behind you, it is important to ensure that your vehicle does not roll backwards when starting from a stop. If your vehicle has a manual transmission, partly engage the clutch before taking your foot off the brake.

24. When driving, the steering wheel should be:
Held with one hand.
Held with both hands on opposite sides of the wheel.

Held with both hands at the top of the wheel.

Hold the steering wheel firmly with both hands, placing them on opposite sides of the wheel.

25. Which of the following does not indicate bad brakes?
Cracked drums
Pads free of oil or grease
Very thin shoes

When inspecting your brakes, you should check for cracked drums; shoes or pads covered in oil, grease, or brake fluid; and shoes that are missing, broken, or worn dangerously thin.

26. If an approaching driver is using their high beam headlights, you should:
Look directly at the headlights.
Flash your high beam lights to remind the driver to switch to their low beams.
Look to the right side of your lane until the vehicle has passed.
Pull to the side of the road until the vehicle has passed.

If a vehicle is coming toward you while using its high beam headlights, glance away from the headlights and toward the right side of the road until the vehicle has passed. This will keep you from being blinded by the lights.

27. Tread depth in the major grooves on a front tire should be at least:
1/32 of an inch.
2/32 of an inch.
4/32 of an inch.
3/4 of an inch.

30. When asked to complete an offset back/right parking maneuver, you should:
Pull straight forward, then back to the right.
Pull straight forward, then back to the left.
Pull forward to the right, then back in a straight line.
Pull forward to the left, then back in a straight line.

If you are asked to complete an offset back/right parking maneuver, you should first pull straight forward, then back up to the right. Your vehicle must be parked completely within the boundaries of the parking space.

31. During a trip, gauges are:
Often misleading.
The only way a driver can learn of potential trouble with the vehicle.
A way to learn of potential trouble with the vehicle.
