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. If driving a truck that requires a CDL for operation:
You do not need to wear a seat belt.
You are required to wear a seat belt, but only if transporting more than 500 pounds of cargo.
You are always required to wear a seat belt.
You are only required to wear a seat belt when driving a tank trailer.

For safety, you must wear your seat belt at all times while operating a CMV.

2. When approaching your vehicle as part of your pre-trip inspection, you should look for what as a sign of trouble?
A puddle of oil under the vehicle
Inflated tires
Lights that are not cracked

When approaching a vehicle for an inspection, you should check underneath it for fresh oil, coolant, grease, or fuel leaked onto the pavement. Any of these could indicate a problem that will need to be repaired before the vehicle is driven.

3. Most heavy vehicles require ____ to change gears.
Double clutching
Double shifting
Triple clutching
Triple shifting

Most heavy vehicles with manual transmissions require double clutching to change gears. A driver should release the accelerator, push in the clutch, and shift into neutral at the same time. After releasing the clutch and allowing the vehicle to change to the necessary speed, the driver should push in the clutch, shift gears, then simultaneously release the clutch and accelerate.

4. Water on bridges:
Usually freezes before water on other parts of a roadway.
Usually freezes after water on other parts of a roadway.
Will not freeze.

Bridges will generally freeze before other parts of the roadway. Be careful on bridges when temperatures are around the freezing point.

5. What does ABS do?
Prevent wheel lockup
Prevent the air compressor from overheating
Prevent the front brakes from being used on ice
Prevent the brakes from being used if downshifting would be more effective

The purpose of an Anti-Lock Braking System (ABS) is to prevent wheels from locking up during hard applications of the brakes, especially on slippery surfaces.

6. About how many drinks does it take for a 200-pound person to reach a 0.02 percent blood alcohol concentration (BAC)?

Alcohol impairment begins long before the legal limit is reached. A 200-pound person will reach a blood alcohol concentration (BAC) of 0.02 percent after a single drink.

7. Loading cargo:
Must be done by the driver.
Can be done by a second person who is responsible for the safety of the cargo.
Can be done by a second person, but the driver is responsible for the safety of the cargo.
Must be done by a person from the shipping company.

Regardless of who has loaded cargo onto a vehicle, the driver is responsible for the safety of the cargo.

A cracked lock ring is acceptable if the vehicle is being driven at speeds under 55 mph.
A missing clamp is dangerous and should be corrected.
Welded repairs are acceptable for wheels on rear axles.

Missing clamps, spacers, studs, or lugs can be a dangerous defect. Mismatched, bent, or cracked lock rings are not safe to be used. Wheels or rims with welded repairs are not safe.

10. Once cargo is secured:
You may complete an entire trip without checking it.
You can drive at least eight hours without checking it.
You should check it every three hours or 150 miles.
You should not check it.

The securement of cargo must be checked before beginning a trip, within the first 50 miles of a trip, and then again every three hours or 150 miles.

11. What is the number one cause of death and injury in work zones?
Speeding drivers
Careless behavior by construction workers
Drivers driving too slowly
Equipment placed in the roadway

Speeding traffic is the main cause of death and injury in work zones. Drive with special caution when traveling near road workers.

12. If driving a vehicle with a manual transmission, you can prevent your vehicle from rolling backward when starting from a stop by:
Partly engaging the clutch before removing your foot from the brake pedal.
Placing the vehicle in reverse before moving forward.
Fully engaging the clutch before removing your foot from the brake pedal.
Placing the vehicle in neutral before moving forward.

To prevent rolling backward when starting from a stop, you should partly engage the clutch before removing your foot from the brake. Apply the parking brake whenever necessary to prevent your vehicle from rolling back.

13. Which of the following determines your blood alcohol concentration (BAC)?
How much you drink
How frequently you drink
The temperature of the drink
The color of the drink

The three main factors that determine a person's blood alcohol concentration (BAC) are how much alcohol was consumed; how fast it was consumed; and the person's body weight. The only thing that can lower a person's BAC is waiting for the alcohol to leave their system naturally.

14. When inspecting cargo, the driver should do all of the following, except:
Ensure that the truck is not overloaded.
Ensure that the cargo is balanced.
Ensure that the cargo is secured properly.
Ensure that the breakable items are placed under heavier items.

15. What is the minimum permitted size of a placard?
Four square inches
Seven square inches
10 ¾ square inches
32 square inches

Hazardous materials must be diamond-shaped and a size of at least 10 ¾ square inches.

16. What can happen if your vehicle has a high center of gravity?
It may get better mileage.
It may be difficult for you to see the road.
It may tip over.
The tires may not be able to handle the weight.

The height of a vehicle's center of gravity is very important. A high center of gravity (cargo piled up high or heavy cargo on the top of a load) increases the possibility of your vehicle tipping over.

17. When traveling down a long downgrade, you should brake by:
Only using the brakes.
Mostly using the brakes and downshifting occasionally.
Downshifting and then using brakes.
Never using the brakes.

On a downgrade, you should use the braking effect of your engine as the principal way of controlling your speed. Save your brakes for additional slowing or stopping that may be required by road or traffic conditions.

18. What can happen if a parking brake is used in very wet weather when temperatures are below freezing?
The brakes will squeak.
The brakes may freeze so the vehicle cannot move.
The brakes may suddenly release by themselves.
The brakes may explode.

If you use the parking brakes when the weather is very wet and the temperature is below freezing, the brakes may become frozen, preventing the vehicle from moving.

19. If you identify a large box in your lane on the road ahead, you should:
Slow down.
Speed up.
Not be worried because another vehicle will likely hit it before your vehicle.
Swerve into another lane of traffic.

Slow down and be very careful if you see foreign objects in your lane. Remember that even something that seems relatively light and harmless, like a cardboard box, could contain harder or heavier items that could cause damage to your vehicle.

20. A modulating control valve can control the:
Spring brakes.
Landing gear.
Air brakes.
Anti-lock braking system (ABS).

A modulating control valve allows a driver to gradually apply spring brakes. In equipped vehicles, the valve is controlled by a lever located on the dashboard.

21. If a person operates in both excepted and non-excepted intrastate commerce, which type of license should the driver select?
Either excepted or non-excepted

To operate in both excepted intrastate commerce and non-excepted intrastate commerce, you must choose a non-excepted intrastate commerce license.

22. When encountering fog, you will be safest if you:
Stay in the left lane.
Don’t drive in the fog.
Use your low beam lights.
Follow the vehicle ahead of you closely.

Fog can quickly deteriorate drivers' ability to see the road, other drivers, and other hazards. Avoid driving in fog if at all possible.

23. While driving, if it is discovered a vehicle's ABS is not working, the driver should:
Put on their hazard lights.
Brake normally.
Use their parking brake to stop.

If an Anti-Lock Braking System (ABS) is not working, the vehicle's basic braking functions are still intact. The driver should continue to drive and brake in a normal fashion.

24. During a basic vehicle control skills test, you may be asked to:
Pull forward into a parking space.
Drive in a figure eight.
Alley dock.
Sound your horn.

Maneuvers that may be included in the basic vehicle control skills test include straight line backing, offset back/right parking, offset back/left parking, driver side parallel parking, conventional parallel parking, and alley docking.

25. If required to complete a vehicle inspection report in writing, the report must be signed:
Every day.
Only if defects have been noted and certified to have been repaired.
Only if the repairs are estimated to cost more than $1,000.
Only if requested to do so by a law enforcement officer.

You must sign the previous vehicle inspection report only if defects were noted and certified to have been repaired or not needing to be repaired.

26. If wheel bearing seals are leaking, you should:
Get the seals fixed.
Not be concerned.
Add more grease until the seal seems full.
Add brake fluid to the bearing.

When inspecting a vehicle, you should ensure that the wheel bearing seals are not leaking. If you find anything unsafe during the vehicle inspection, get it fixed. Federal and state laws forbid operating an unsafe vehicle.

27. Texting while driving is worrisome:
Because it creates both mental and physical distractions.
Because a message may be upsetting to the driver.
Because the texts may be more interesting than the task of driving.
Because it is less efficient than a phone call.

When driving, texting is a particularly dangerous distraction because it distracts a driver both mentally and physically.

28. On a wet road, you should reduce your speed:
By about one-half.
By about one-third.
By about one-quarter.
By about one-eighth.

You should reduce your speed by about one-third when driving on a wet road. It can be difficult to stop or turn when operating on a slippery surface, so you must adjust your speed to drive safely under such conditions.

29. How much water must be on a road surface for a vehicle to hydroplane?
Usually several inches
A good amount, such as a large puddle
A small amount

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 much water on the road for this to occur.

30. A driver can have:
Two licenses, one for automobiles and one for trucks.
Only one license.
A license for each state in which they plan to drive.
An automobile license from one state and a CDL from another.

A person cannot have more than one license. States share driver data through a computer database to prevent the issuance of duplicate licenses.

31. When carrying a wide load, a driver should:
Drive as fast as possible.
Obtain special permits and follow special rules, such as driving only during certain times.
Honk at other drivers to get them to move from the nearest lane.

Loads that are over-length, over-width, or overweight require special permits and may be subject to restrictions, such as being allowed on the road only at certain times of the day.

32. Of the following, which is not a way to prevent drowsiness during a trip?
Getting an adequate amount of sleep before driving
Traveling with a passenger
Scheduling trips during hours when you would not normally be awake
Avoiding medications that may cause drowsiness

Driving while fatigued can be extremely dangerous. Strategies for preventing drowsiness while driving include getting a full night's sleep before a trip; having someone ride with you so you can take turns driving; scheduling trips for times during which you are normally awake; and avoiding medications that may cause drowsiness.

33. A danger of a large truck swerving to avoid a hazard is:
The truck may miss the object.
The truck may flip over.
The truck may stay in the same lane.
Other vehicles may do the same thing.

Swerving out of the way of a hazard is sometimes safer than trying to stop before reaching the hazard. You can usually turn away from something more quickly than you can come to a complete stop. However, swerving while in a vehicle that is either top-heavy or pulling multiple trailers may result in a rollover.

34. How many seconds of following distance per every 10 feet of vehicle should you maintain when traveling more slowly than 40 mph?
One second
Two seconds
Three seconds
Four seconds

When traveling at speeds below 40 mph, you should maintain at least one second of following distance for every 10 feet of your vehicle's length. At higher speeds, add an additional second.

35. When steering to avoid a crash, you should:
Only use one hand to steer.
Keep both hands on the steering wheel.
Not use your mirrors to check other lanes.
Speed up as you get nearer to the hazard.

When turning quickly to avoid colliding with a hazard in the roadway, you should always keep both hands on the steering wheel. You must have a firm grip on the wheel to be able to turn quickly.
