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. After an accident, flares should be used with caution because:
There may be spilled fuel on the ground that could ignite.
Other drivers may not see the flares.
Flares are expensive.
Other drivers may get confused about what is happening.

After an accident, spilled fuel and improper use of flares can result in a fire.

2. Which of the following statements is correct?
Rims with a missing lug nut are acceptable if there are at least four other lug nuts on the rim.
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.

3. To receive a hazardous materials endorsement, an applicant will be required to supply:
Their fingerprints.
Their shoe size.
A list of countries visited within the last 10 years.
Their employment history for the previous five years.

To obtain a hazardous materials endorsement, you will be required to submit your fingerprints and undergo a TSA background check.

4. When inspecting engine compartment belts during the vehicle inspection test:
The belts should be checked for snugness, each with up to three inches of play.
The water pump belt does not need to be identified.
The air compressor belt should be removed.
The applicant must identify which items are not belt-driven, if any.

When checking the engine compartment during the vehicle inspection test, you must check the power steering, water pump, alternator, and air compressor belts. In addition to cracks and frays, you should check the belts for snugness, allowing up to three-quarters of an inch of play at the center of each belt. If any of these items are not belt-driven, you must identify them and ensure that their components are operating properly, are not damaged or leaking, and are mounted securely.

5. What is Gross Vehicle Weight (GVW)?
The total weight of a vehicle and its cargo
The total weight of a vehicle before cargo
The total weight of cargo
The maximum weight allowed to be transported by a vehicle

Gross Vehicle Weight (GVW) is the total weight of a single vehicle and its load of cargo.

6. On newer vehicles, how do you put on the parking brake?
Move a lever to the right.
Push in the yellow, diamond-shaped knob.
Pull out the yellow, diamond-shaped knob.
Pull up on the steering column.

On newer vehicles with air brakes, the parking brake is controlled by a yellow, diamond-shaped knob. The knob is pulled out to set the brakes, and pushed in to release them.

7. When entering fog, you should:
Put on your high beam headlights.
Increase your speed.
Turn up the volume of the radio.
Slow down.

If at all possible, it is best to avoid driving in fog. However, if you must drive through fog, slow down before reaching it.

8. You should not use the parking brake:
If your vehicle is stopped on a level surface.
If your vehicle is stopped on a slight incline.
If your vehicle's brakes are very hot.
If your vehicle's other braking systems seem to be working adequately.

A parking brake should not be used if the vehicle's brakes are very hot from use on a steep downgrade or if the brakes are very wet and temperatures are freezing. Using the parking brake when brakes are hot could cause damage to the brakes, and using the brakes when they are wet in freezing weather may cause the brakes to ice up, rendering the vehicle immobile.

9. If your vehicle is equipped with a cargo lift, you should ensure that:
The lift is loosely attached.
The lift is not leaking.
The lift is fully extended.
The lift is the proper color.

When checking a cargo lift as part of your vehicle inspection test, you should check for leaking, damaged, or missing parts. The lift must be fully retracted and latched securely.

10. In very hot weather, tires should be checked regularly because:
They may melt.
Air pressure may increase with the temperature.
The tread wears down extra quickly.
The lug nuts may loosen.

Air expands as it gets warmer, so the air pressure in your tires could reach dangerously high levels while being used in very hot weather. If this happens, stop and let your tires cool. Do not let air out of the tires, as this could result in the pressure dropping to an unsafe level once the tires cool down.

11. How many points will be added to your driving record for speeding between 11 and 14 mph over posted speed limit?

In West Virginia's point system, driving between 11 mph and 14 mph faster than the posted speed limit will incur three points on a driver's record. If a driver accrues 12 points or more, their license will be suspended.

12. When taking the on-road driving test, you must do all of the following, except:
Wear your safety belt.
Obey all traffic signs.
Complete the test without an accident.
Demonstrate that you can use your cell phone while driving.

During the on-road driving test, you must drive in a safe and responsible manner; wear your safety belt; obey all traffic signs, signals, and laws; and complete the test without any accidents or moving violations.

13. How can you avoid becoming drowsy on a trip?
Get about three hours of sleep beforehand.
Plan ahead, including stopping points.
Do not build exercise into your daily routine.
Schedule the trip at night.

Strategies to reduce the risk of fatigue while driving include getting seven to eight hours of sleep beforehand; scheduling trips for the hours during which you are normally awake; planning to take breaks during the trip; and exercising regularly.

14. Bent lock rings:
Are acceptable.
Are not a concern in dry weather.
Are dangerous.
Can lengthen tire life.

Mismatched, bent, or cracked lock rings are dangerous and should not be used.

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

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.

16. Braking mechanisms are located ____ a brake drum.
Next to
On top of

Drum brakes are attached to the wheels and located on the axles of a vehicle. The braking mechanisms that cause the vehicle to stop can be found inside of a drum brake.

17. When the brake pedal is depressed, air brakes work:
After a short delay.
After about a minute.
Only if the green lever on the control panel is pushed down.

After the brake pedal is pushed down in a vehicle with air brakes, it takes a half-second or more for air to flow through the lines and make the brakes work. This contrasts with hydraulic brakes used in cars and light and medium trucks, which instantly begin working when the pedal is pushed.

18. A driver should always:
Stay in their lane.
Have an emergency plan.
Stay in the left lane.
Drive above the speed limit.

While driving, you should continually scan the road ahead to spot potential hazards well in advance. Make emergency plans for how to deal with the hazards in the event that they become dangerous.

19. During a trip, which of the following does not need to be checked regularly?
Pressure gauges
Seat cushion

During a trip, you should regularly monitor the instruments, gauges, meters, and mirrors. Check the tires, cargo, and lights for signs of trouble.

20. When completing pre-trip inspections:
The inspections should be done the same way each time.
Different items should be checked each time.
It is acceptable to check items in a different order each time.
Not every item needs to be inspected each time.

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.

21. If you see lights ahead while driving in fog:
You can assume the lights are on the road.
It may be a reflection.
It may be an optical illusion.
The lights may not indicate where the road is as the vehicle may have pulled off the roadway.

When driving under foggy conditions, lights cannot be taken as a reliable indication of where the road is. The lights may be coming from a vehicle that has pulled off the road.

22. Don't spend too much time looking at a single mirror because:
Conditions can change quickly.
Looking at mirrors can make you drowsy.
It can result in you driving a long distance without looking at the road.
The mirror may not provide an accurate view of the road.

Check you mirrors frequently while driving, but check them quickly. Staring at one mirror for too long can cause you to drive a long distance without knowing what is ahead.

23. If you have more than one license:
You are unlikely to be caught.
You are doing nothing wrong.
You will be penalized.
There is no way for authorities to find out.

A person may not have more than one license. Violation of this law may be punishable by jail time and/or a fine of up to $5,000.

24. When the spring brakes are activated in a vehicle with air brakes, you should never:
Turn on the lights.
Turn the vehicle off.
Push the brake pedal down.
Open the trailer doors.

In a vehicle with air brakes, never push the brake pedal down when the spring brakes are activated. The combined force of the springs and the pressure of the air brakes could damage the brakes.

25. Which of the following is not a sign of a person being drowsy?
Frequent blinking
Drifting from your lane
Feeling hungry

Driving drowsy is dangerous and should always be avoided. Warning signs of drowsiness include frequent blinking, your eyes closing or going out of focus by themselves, frequent yawning, and drifting between lanes.

26. When checking the power steering fluid during a vehicle inspection, you will need to do each of the following, except:
Show where the power steering fluid dipstick is located.
Check for adequate power steering fluid.
Ensure that the power steering fluid level is above the full mark.
Ensure that the power steering level is above the refill mark.

When checking the power steering fluid during the vehicle inspection test, you must be able to indicate where the power steering fluid dipstick is located and show that there is an adequate amount of power steering fluid in the engine compartment. The fluid level must be above the refill mark.

27. The service brake system:
Applies and releases the brakes when you press the brake pedal while driving normally.
Applies and releases the parking brakes.
Applies and releases the emergency brake.
Applies and releases the axle brake.

Air brakes consists of three separate braking systems: the service brake system, the parking brake system, and the emergency brake system. The service brake system applies and releases the brakes when you use the brake pedal while driving normally.

28. When stopping a manual transmission vehicle, what should you do when the engine is close to idle?
Push in the clutch.
Push out the clutch.
Shift into neutral.
Shut off the vehicle.

When stopping a vehicle with a manual transmission, you should push in the clutch when the engine is close to idle.

29. During a static leakage test, the maximum leakage rate for a double combination vehicle is:
3 psi in one minute.
6 psi in one minute.
8 psi in one minute.
4 psi in one minute.

When performing a static leakage test on a double combination vehicle with air brakes, the leakage rate should be no more than 3 psi in one minute. If air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.

30. 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.

31. When you must travel down a grade, when should you switch into a lower gear?
Before beginning the grade
After you have already started the grade
As far down the grade as possible
At the bottom of the grade

Before starting down a hill, you should shift into a lower gear. This will help get your vehicle to a speed that you can control without having to use your brakes too much.

32. When entering a curve, you should:
Get off the roadway.
Use the shoulder.
Take the vehicle out of gear.

It is important to take turns and curves at a safe speed. You should always downshift before entering a curve.

33. The Individual Vehicle Distance Record (IVDR) must include all of the following, except:
The date of trip.
The route of travel.
The total distance traveled.
The number of stops.

An Individual Vehicle Distance Record (IVDR) must include the following information about distance traveled: trip start and end dates; trip origin and destination points; route(s) of travel; beginning and ending odometer or hubometer readings; total distance traveled; in-jurisdiction distance; and power unit number or vehicle identification number.

34. An applicant will be denied a hazardous materials endorsement if they:
Are a U.S. citizen.
Are wanted for a misdemeanor.
Are wanted for certain felonies.
Already have a driver license.

Your application for a hazardous materials endorsement can be denied, or your existing endorsement canceled, if you do not have legal permanent status in the United States; you renounce U.S. citizenship; you are wanted for, under indictment for, or convicted of certain felonies; you are judged mentally incompetent or are involuntarily committed to a mental institution; or you are deemed by the Transportation Security Administration to pose a security threat.

35. While driving, if it is discovered a vehicle's ABS is not working, the driver should:
Put on their hazard lights.
