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. Be sure that your wheel bearing/seals are:
Not leaking.

During an inspection, ensure that the wheel bearing/seals are not leaking.

2. What kind of brakes do most newer heavy-duty trucks use?
Single air brakes
Dual air brakes
Triple air brakes

Most newer heavy-duty vehicles use dual air brake systems. A dual air brake system has two separate air brake systems which use a single set of brake controls.

3. When entering a curve, you should:
Shift into neutral.
Use the shoulder.

You should always slow down to a safe speed and shift into a lower gear before entering a curve.

4. When starting an engine:
The brakes will lock up.
Warning lights should turn on, then quickly turn off.
Coolant temperatures should decrease.

After a vehicle is started, the warning lights and buzzers should go out after a few seconds. If the warning signals do not turn off, there may be something wrong with the vehicle.

5. If the brakes pull to one side or the other when used:
They are working properly.
They need to be checked.
They will be the most effective.

If the brakes pull to one side or the other when used, it is an indication of brake trouble.

6. When driving, knowing what is happening behind you is:
Rarely important.

To travel safely, it is essential that you know what is happening on all sides of your vehicle at all times. Use your mirrors frequently to help you remain aware of your surroundings.

7. Some water and compressor oil is usually found in the compressed air within an air brake system. The water and compressor oil:
Are necessary for the proper function of the system.
Should take up about 10 percent of the tank.
Should be removed regularly.

If water and compressor oil are left to build up in an air brake system, the system can be damaged. Air storage tanks are equipped with drains to allow this accumulation to be removed. Manually controlled drains should be operated at the end of each day of driving.

8. When making a left turn where there are two available turn lanes, a driver should begin the turn in the rightmost lane because:
It will be easier for the driver to keep track of turning vehicles on their left than on their right.
The vehicle will be able to turn more quickly.
Other vehicles will get out of the turning vehicle's way.

If making a left turn where there is more than one available turn lane, you should always choose to begin your turn in the rightmost lane. Large vehicles often have to swing right to make left turns. Because of this, it is safer for you to have other left-turning traffic to your left instead of to your right. This will allow you to have the best possible view of other turning vehicles and will lower the risk of your vehicle colliding with them.

9. When doing a pre-trip inspection, you should:
Always go through the steps in the same order.
Be as quick as possible.
Not worry about small mechanical issues.

Pre-trip inspections should be conducted in the same way every time. This will reinforce the steps, making it less likely that you will forget to inspect something important.

10. When traveling in heavy traffic, the safest driving speed is:
The posted speed limit.
The speed of surrounding traffic.
A speed much slower than the flow of surrounding traffic.

In heavy traffic, it is safest to match the speed of surrounding vehicles. Vehicles traveling in the same direction at the same speed are unlikely to collide. However, you should not exceed legal speed limits.

11. 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.

12. When pulled off on the side of the road:
A driver should keep the driver’s side door open.
A driver should turn on the emergency flashers.
The driver should wave their arms.

If you must stop on the side of the road, make sure to use your four-way emergency flashers. This is particularly important at night.

13. Hydroplaning:
Rarely occurs with large trucks.
Usually happens when vehicles are traveling faster than 65 mph.
Can occur with a minimal amount of water on the roadway.

Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be a large amount of water on the road for this to occur.

14. When completing an offset back/left parking maneuver, a driver should:
Pull straight forward, then back to the left.
Drive straight back, then pull forward to the left.
Pull straight forward, then drive straight back.

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

15. When changing lanes:
You should not use your mirrors.
You should use your mirrors.
You should not use your turn signals.

Always use your turn signals and check your mirrors when changing lanes.

16. Rims with welding repairs:
Are not safe to use.
Are acceptable to be used on tires in the rear of the vehicle.
Are acceptable to be used if carrying a light load.

Wheels or rims with welding repairs are never safe to use.

17. When performing a pre-trip inspection and looking into the fifth wheel gap, you should:
Make sure there is a gap between the kingpin and the locking jaws.
Make sure the locking jaws are fully closed around the kingpin.
Make sure the locking jaws are loose.

When inspecting a tractor/trailer coupling, look into the fifth wheel gap and make sure the locking jaws are fully closed around the kingpin.

18. If you are turning left at an intersection where there are two available turn lanes:
It is best to use the right lane.
It doesn’t matter which lane you use.
It is best to use the left lane.

You may have to swing right to safely make a left turn. If there are two left turn lanes available at an intersection, you should always begin your turn in the rightmost lane.

19. If you are convicted of a traffic violation:
The State will inform your employer.
You must tell your employer.
You must tell the shipper.

If you are convicted of any kind of traffic violation, in any type of vehicle, you must notify your employer within 30 days. You must also inform your motor vehicle licensing agency of the violation within 30 days if the conviction happened in another jurisdiction. This rule does not apply to parking infractions.

20. 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.

21. An applicant for a CDL must be a minimum of:
18 years old.
21 years old.
25 years old.

In Vermont, you must be at least 18 years old to obtain a CDL. To be licensed to operate in interstate commerce, you must be at least 21 years old.

22. Steering wheel play should be no more than:
10 degrees.
50 degrees.
75 degrees.

A steering wheel should have no more than 10 degrees of play. This is equal to about two inches of movement at the rim of a 20-inch wheel. If there is more play than this, it may be difficult to steer.

23. 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.

24. If driving through flowing water or a large puddle, you should:
Increase your speed.
Gently apply the brakes.
Try to stop in the water.

It is best to avoid driving through large puddles or moving water. If there is no way to avoid driving through water, you should slow down, shift into a low gear, and gently apply the brakes. Pressing linings against the brake drums or discs will keep water, mud, silt, and sand from getting inside the brake mechanisms.

25. The ____ are activated by an electric switch that is triggered by the brake pedal.
Turn signals
Brake lights

In a vehicle with air brakes, the brake lights are activated when the brake pedal is pushed and air pressure moves an electric switch. With the application of air pressure, the switch will then turn on the brake lights.

26. Alcohol evaporators are:
Used to introduce alcohol into air brake systems.
Only allowed in the northern parts of the state.

Some air brake systems have alcohol evaporators, which introduce alcohol into the braking system to help prevent the formation of ice.

27. If you are driving in fog, you should not:
Turn on the four-way flashers.
Slow down.
Use your high beam lights.

If you must drive in fog, be sure to slow down. Turn on your flashers and low beam headlights.

28. You should not use your mirrors:
When changing lanes.
When making a turn.
To determine how fast you are traveling.

While regular mirror checks should be a part of your driving routine, it is particularly important to check your mirrors when changing lanes, turning, merging, and making tight maneuvers.

29. If you are disqualified from driving:
Your employer will be notified by the state.
You must notify your employer within two business days.
You must notify your employer within a month.

You must notify your employer within two business days if your license is suspended, revoked, or canceled, or if you are otherwise disqualified from driving.

30. If asked by a law enforcement officer to take a test to determine your blood alcohol concentration (BAC):
You can refuse to take the test without a penalty.
You can refuse taking the test but will be required to pay a $50 fine.
You will lose your CDL if you refuse to take the test.

Most states have an Implied Consent Law, which means that by driving a vehicle on the state's roads, you have agreed to undergo a drug or alcohol test if a police officer asks you to do so. If you refuse to submit to a test, you will lose your operating privileges. Make sure you are aware of the laws for every state in which you drive.

31. What is a retarder?
A device that prevents a vehicle from going too fast
A device that prevents a vehicle from being too loud
A device that improves a vehicle's gas mileage

Retarders help to slow vehicles, reducing drivers' need to use brakes.

32. Cargo with a high center of gravity:
Can make a vehicle likely to tip over.
Is encouraged in inclement weather.
Is required on some roads.

Cargo with a high center of gravity makes a vehicle more likely to tip over than cargo with a low center of gravity. For this reason, it is important that the weight of cargo be distributed as low as possible.

33. Cargo should be covered:
To protect people from spillage.
To hide the materials.
To make it more difficult to steal.

You should cover your cargo to protect people from the cargo if it spills, as well as to protect the cargo from the weather.

34. When stopping, you should:
Press down the brake pedal quickly.
Press down the brake pedal gradually.
Lift up the brake pedal quickly.

When stopping, press down the brake pedal smoothly and gradually.

35. Once the air tanks are at an air pressure level of 125 psi, the air compressor governor will:
Stop the compressor from pumping air.
Release air from the tanks.
Begin pumping air into the tanks.

An air compressor governor will stop the compressor from pumping air once the air tanks are at an air pressure level around 125 psi. This air pressure level is referred to as the "cut-out" level.
