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. What does blocking cargo do?
Holds the cargo in a large box
Prevents cargo from sliding in transit
Prevent others from buying the cargo

Blocking and bracing are used to prevent cargo from shifting in transit.

2. Which of the following is a good rule to follow when making a turn?
Honk your horn.
Use your arms to get the attention of other drivers.
Turn off your turn signal before entering the turn to avoid confusing other drivers.
Signal early.

Signal well in advance of a turn so drivers behind you are aware of your intentions. Keep the signal on throughout the turn and turn it off once the turn is complete.

3. When checking the engine compartment:
The parking brake should not be engaged.
Wheels should be chocked.
The engine should be running.
The gearshift should be in first gear.

Before inspecting the engine compartment, make sure that the parking brakes are on and/or the wheels are chocked. Check the engine compartment before entering the cab and starting the engine.

4. Testing positive for any amount of alcohol while still below the legal limit will result in a driver being placed out-of-service for 24 hours.

If you are found to have any detectable amount of alcohol in your system, but are still below the legal limit of 0.04 percent, you will be placed out-of-service for 24 hours. It is both illegal and dangerous to operate a motor vehicle while under the influence of alcohol.

5. A stopped bus:
Is not a cause for concern since it is stopped.
Is only a concern if passengers are exiting the bus.
Is a concern whether or not passengers are visible.

You should always exercise caution when driving near a stopped bus. There could be passengers in the vicinity and the bus may either prevent them from seeing you or you from seeing them.

6. Always perform the steps of a pre-trip inspection in the same order each time because:
You will be less likely to forget something.
You will have more time to complete the inspection.
It is required by law.

Completing the steps of a vehicle inspection in the same order before every trip aids in learning what the proper steps are. Additionally, you be less likely to forget a step when going through the checklist in a prescribed order.

7. Broken suspension parts:
Should not concern you.
Should be repaired, but do not need to be repaired immediately.
Cannot be identified.
Are extremely dangerous.

The suspension system is responsible for supporting a vehicle, supporting its load, and keeping its axles in place. When inspecting your vehicle, check for damaged or missing spring hangers, spring leaves, shock absorbers, u-bolts, and frame members. Broken parts in the suspension system are extremely dangerous.

8. When starting your vehicle, the coolant temperature should:
Not change.
Increase gradually.
Quickly jump from low to high.

Watch the gauges in your vehicle before starting a trip. After starting your vehicle's engine, the coolant temperature should begin a gradual rise to the normal operating range.

9. States verify that a CDL or CLP driver has only one such license by:
Making phone calls to surrounding states.
Using a computerized system that links all states.
Asking the driver.
Looking through the driver's wallet.

All U.S. states share information about CDL and CLP licenses in a computerized database. If you apply for a license in one state, a state will check this database to verify that you do not already have one such license in another state.

10. When using a fire extinguisher on a fire, you should:
Get as close to the fire as possible.
Stay as far away from the fire as possible.
Aim the extinguisher at the top of the flames.
Aim the fire extinguisher at the ground about two feet away from the fire.

When using a fire extinguisher, you should stay as far away from the flames as possible and aim at the base of the fire.

11. When taking the on-road driving test, you will be evaluated on your lane usage. Which of the following is an example of poor lane usage?
Not driving over curbs or sidewalks
Stopping behind crosswalks
Driving in the leftmost lane if more than one driving lane is available
Finishing a right turn in the rightmost lane

During the on-road driving skills test, make sure you do not put your vehicle over curbs, sidewalks, or lane markings. Stop behind stop lines, crosswalks, or stop signs. On multiple-lane roads, complete turns in the proper lane. Always move to or remain in the rightmost lane, unless the lane is blocked.

12. During a basic vehicle control skills test, a look is when:
A driver checks the gauges on their instrument panel.
A driver checks their blind spots.
A driver walks to the back of their vehicle to check its position.

A driver uses a look when they open their door, leave their seated position, and walk to the back of the vehicle to check its position. During the straight line backing exercise, a driver may not exceed one look. During any other exercise, a driver may not exceed two looks.

13. Distracted driving:
Is not a concern.
Only occurs as a result of people who are physically doing something while driving.
Can occur as a result of mental activities, such as daydreaming.
Is encouraged on uncrowded roads.

Distractions while driving can be physical (such as reaching for an object), mental (such as making conversation with a passenger), or both (such as holding a phone to send texts). Strategies to help you avoid distracted driving include pre-programming radio stations; planning out your route in advance; avoiding complex or emotionally taxing conversation while driving; adjusting your mirrors before setting out; and not eating, drinking, or smoking while behind the wheel.

14. Rough acceleration:
Can damage parts of a vehicle.
Is necessary to warm up parts of a vehicle.
Is encouraged to improve a vehicle's gas mileage.

Always speed up smoothly and gradually so that your vehicle does not jerk. Rough acceleration can cause mechanical damage.

15. When approaching your vehicle as part of a pre-trip inspection, seeing fresh oil underneath the vehicle is:
A good sign.
A cause for concern.

When approaching your vehicle, you should check under the vehicle for fresh oil, coolant, grease, or fuel leaks. Spotting any of these before a trip is a cause for concern.

16. When starting a trip while transporting a load, the driver should:
Stop to check on the cargo within the first 50 miles of the trip.
Drive faster than usual to test the security of the load.
Only use the side mirrors to check on the cargo.
Not recheck the cargo if it was secured properly before starting the trip.

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 thereafter.

17. Air tank drains:
Allow rain water to enter the tank.
Are used to drain water and compressor oil from the air tank.
Should never be opened.
Must remain open during transit.

In an air brake system, the air storage tanks must be drained to remove accumulated water and compressor oil. Failing to do so can cause damage. Manually operated drains should be used at the end of each day of driving.

18. Mirrors should be adjusted:
While moving.
When the trailers are straight.
When you are standing next to the vehicle.
By an assistant.

Mirrors should be checked prior to the beginning of a trip. On a vehicle with a trailer, mirror adjustment can only be checked accurately if the connected trailer is straight.

19. To avoid a hazard, you:
Should always come to a complete stop.
May need to swerve your vehicle out of the way.
Should change lanes without looking.

Stopping is not always the best way to avoid a hazard. If there is not enough space for you to stop to avoid coming into contact with the hazard, swerving out of the way may be your safest option.

20. When should a turn signal be canceled by a driver?
Before entering a turn
While turning
After a turn is completed

If your vehicle does not have self-canceling turn signals, be sure to cancel your turn signal after completing a turn.

21. If a CMV driver operates a CMV with a detectable blood alcohol concentration (BAC) that is lower than 0.04 percent, they will be:
Told to stop drinking.
Put out-of-service for 24 hours.
Required to drive at speeds below 55 mph.
Told to drive home.

If you are found to be operating a CMV with any detectable amount of alcohol in your system, but you are still below the legal limit of 0.04 percent, you will be placed out-of-service for 24 hours. It is both illegal and dangerous to operate a motor vehicle while under the influence of alcohol.

22. Headache racks:
Are illegal.
Help protect the driver from the cargo.
Allow for increased cargo space.

Front-end header boards, also known as "headache racks," protect the driver from cargo moving in the event of a crash or emergency stop.

23. The parking brake should be:
Used whenever you park the vehicle.
Used while driving.
Set when driving in bad weather.
Used to stop the vehicle in normal driving.

The parking brake should be applied every time you park your vehicle.

24. If you are being tailgated, you should:
Drive on the shoulder.
Pull off the roadway.
Drive faster.
Allow the vehicle to pass.

If someone is tailgating you, it is a good idea to open up the space ahead of your vehicle to make it easier for the driver to pass you. Increasing your speed is not a good idea because the driver may continue to tailgate you at the higher speed, only increasing the danger.

25. Traction is important in:
Safe braking.
Properly using turn signals.
Operating the horn.

You will not be able to brake or steer your vehicle without adequate traction. Ensure that your tires are in proper working condition before beginning a trip.

26. A tank endorsement is:
Only required when transporting gases.
Only required when transporting liquids.
Required to transport both liquids and gases.
Optional when transporting hazardous materials.

Subject to certain conditions, a tank endorsement is required to operate a tank vehicle that is used to haul either liquids or gases.

27. Mirrors should be:
Checked only when changing lanes.
Checked frequently.
Checked only if there is a reason to suspect a problem.

When driving, you should regularly check your mirrors, both to be aware of traffic and to check for problems on your own vehicle.

28. Parts of an exhaust system should be:
Fastened securely.

When inspecting an exhaust system, you should verify that parts of the system are not loose, broken, or missing. The system's parts must be properly mounted and should not be rubbing against moving parts of the vehicle.

29. What is the Gross Vehicle Weight Rating (GVWR)?
The maximum permitted total weight of a vehicle and its cargo
The minimum permitted weight of a trailer
The maximum permitted weight of a trailer and its contents
The maximum permitted weight of only a tractor

The Gross Vehicle Weight (GVW) is the total weight of a single vehicle plus its load. The Gross Vehicle Weight Rating (GVWR) is the maximum combined weight of a vehicle and its cargo that is permitted and specified by the manufacturer.

30. Retreaded tires:
May be used on any part of a bus.
May be used on the front of a bus.
May be used on the rear of a bus.
May never be used on a bus.

Regrooved, recapped, or retreaded tires are prohibited from use on the front wheels of a bus.

31. When alley docking, you should first:
Position your vehicle directly in front of the alley.
Back up directly in front of the alley.
Stop parallel to the outer boundary of the alley.

If you are asked to alley dock, you should first pull past the alley and stop your vehicle in a position that is parallel to the outer boundary. From there, you should back your vehicle entirely into the alley parking area. Your vehicle should be parked in a straight position within the boundaries of the parking space.

32. Rough acceleration:
Is recommended.
Can cause mechanical damage.
Is required on slippery surfaces.

Always speed up smoothly and gradually so that your vehicle does not jerk. Rough acceleration can cause mechanical damage.

33. When driving down a steep grade, your brakes may fade. What happens if brakes fade?
They become quieter.
They become less effective.
They work better than usual.
They work differently from front to back.

If you use your brakes too much when traveling on a steep downgrade, they may overheat and become less effective. To avoid causing your brakes to overheat on a steep hill, you should rely on engine braking.

34. Which of the following is not an indicator of when to upshift?
Road speed

There are two indicators that determine when you need to shift into a higher gear. One indicator is the engine speed (rpm). You should read your vehicle's manual to learn its rpm range and shift up when you reach the top of that range. The other indicator is road speed (mph). You should learn which speeds each gear can accommodate, then keep an eye on the speedometer and shift up as needed.

35. What is the average driver’s reaction time?
One-sixteenth of a second
One-eighth of a second
Between three-quarters of a second and one second
Two seconds

The average driver has a reaction time of between three-quarters of a second and one second.
