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. Talking on a hands-free phone while driving:
Does not distract the driver.
Only distracts the driver if the driver is speaking.
Can be distracting to the driver.

While speaking on a hands-free phone while driving is less dangerous than speaking on a hand-held phone, it is just as likely to mentally distract a driver. Simply engaging in conversation takes their mental focus away from the task of driving.

2. When backing with a trailer, you should begin by:
Turning the steering wheel in the direction of the turn.
Turning the steering wheel in the direction opposite of the turn.
Turning the wheel as sharply as possible.

When backing with a trailer, begin by turning the steering wheel in the direction opposite of the turn. Once the trailer starts to turn, reverse the direction of the steering wheel to follow the trailer.

3. During an applied leakage test, what is the maximum leakage rate that is safe for a single vehicle with air brakes?
10 psi in one minute
5 psi in one minute
3 psi in one minute

It is important to know the maximum air loss rate that is safe for your specific vehicle. A single vehicle with air brakes should have a leakage rate no higher than 3 psi in a minute during an applied leakage test.

4. When traveling long distances, you should:
Take rest breaks.
Drive as fast as possible.
Drive through the night.

To avoid becoming fatigued on a long trip, you should take a break after every 100 miles or two hours of driving. Driving through the night, or during any other time when you would normally be asleep, raises the danger of fatigue.

5. When pulled over to the side of the road, you should:
Rely on your taillights to alert other motorists to your presence.
Not worry about other motorists.
Use your four-way emergency flashers to alert other motorists to your presence.

When stopped on the side of the road, be sure to turn on your vehicle's four-way emergency flashers, especially during times of lowered visibility. Place warning devices within 10 minutes of being stopped.

6. A second conviction of operating a CMV with a minimum blood alcohol concentration (BAC) of 0.04 percent will result in:
The loss of your CDL for life.
The loss of your CDL for five years.
The loss of your CDL for one year.

It is illegal to operate a CMV if your blood alcohol concentration (BAC) is 0.04 percent or higher. A first offense will result in the loss of your CDL for one year. A second offense will result in the loss of your CDL for life.

7. Air pressure should build up in a single air system within:
15 minutes.
12 minutes.
Three minutes.

In single air systems, air pressure should build from approximately 50 to 90 psi within three minutes.

8. When transporting cargo, drivers must check the securement of the cargo every:
10 miles.
150 miles.
500 miles.

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

9. Which of the following is not a type of distraction?

Distractions that can affect safe driving can be classified as physical (such as reaching for an object), mental (such as talking with passenger), or both (such as talking on a hand-held phone).

10. When stopping a manual transmission vehicle, you should:
Push the clutch in when the engine is close to idle.
Push the clutch out when the engine is close to idle.
Shift into neutral when the engine is close to idle.

When stopping, apply gradual pressure to the brake pedal and stop smoothly. If stopping a manual transmission vehicle, push the clutch in when the engine is close to idle.

11. When turning, when should the turn signal be canceled?
Before entering the turn
During the turn
After the turn is completed

Always signal continuously through a turn. Do not cancel a signal until the turn is finished.

12. In a vehicle with dual parking control valves, a separate air tank can be used:
To make the air brakes work more effectively.
To temporarily release the spring brakes.
To charge the brakes on the rear trailer.

In a vehicle with dual parking control valves, there is a separate air tank that can be used to temporarily release the spring brakes if they have been activated due to low air pressure. Pushing in the proper control will release the spring brakes for a short period of time, allowing the driver to move the vehicle in an emergency.

13. When are people usually the least alert?
In the morning
In the early evening
Late at night

Most drivers are the least alert at night, especially after midnight. Therefore, crashes due to fatigued driving are more likely at night than any other time of day.

14. What is reaction distance?
The distance you will travel between realizing you must brake and when you physically hit the brakes
The distance you will travel between a hazard becoming visible and you seeing the hazard
The distance you will travel between seeing a hazard and realizing you must brake

Your vehicle's stopping distance can be calculated by adding together your perception distance, your reaction distance, and your vehicle's braking distance. Reaction distance is the distance traveled between the moment you mentally perceive a hazard and the moment you physically hit the brakes.

15. Which of the following is not a sign of fatigue?
Difficulty focusing, with frequent blinking
Yawning repeatedly or rubbing eyes
Staying in your lane

Potential warning signs of fatigue include difficulty focusing, frequent blinking, or heavy eyelids; yawning repeatedly or rubbing your eyes; daydreaming; wandering or disconnected thoughts; trouble remembering the last few miles you've driven; missing exits or traffic signs; having trouble keeping your head up; drifting from your lane; following too closely; hitting a shoulder rumble strip; or feeling restless and irritable.

16. When loading a trailer, weight should be:
Placed as high as possible.
Placed as low as possible.
Placed as far to the left as possible.

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.

17. To avoid a hazard:
You should always steer to the left.
You may be able to drive onto the shoulder.
You should steer sharply in one direction.

In some emergencies, the best strategy for avoiding a hazard may be to drive onto the shoulder. Most shoulders are strong enough to support the weight of a large vehicle.

18. If a vehicle is power steering-equipped, the hoses should be:
Checked for leaks.
Securely connected to the battery.
Carrying fuel.

When inspecting a vehicle equipped with power steering, you should inspect the hoses, pumps, and fluid levels. Specifically check the hoses for leaks.

19. 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.

20. If you realize you may be running late to your destination, you should:
Speed up.
Get upset.
Deal with it and drive at a safe speed.

To reduce the risk of developing aggressive driving behavior, you should take measures to manage your stress. One strategy to do this is to simply take a deep breath and accept your circumstances if you realize you will be late to your destination.

21. On a slippery road, a driver should:
Make turns as quickly as possible.
Refrain from passing slower vehicles.
Stop quickly.

Under slippery conditions, you should drive slowly and smoothly. Make turns as gently as possible and do not pass other vehicles unless you have to.

22. When leaving your vehicle unattended:
The parking brake must be always be used.
The parking brake should never be used.
Windows in the cab should be lowered.

Always apply the parking brake when leaving your vehicle unattended.

23. Roads are especially slippery when it first begins to rain because:
Water is always very slippery.
The fresh rain mixes with oil on the roadway.
The water has nowhere to go.

Roads are particularly slippery when it first begins to rain. The water mixes with oil drippings on the road that have not yet washed away, creating a slippery and dangerous mixture.

24. The more alcohol in the body:
The quicker the liver will digest the alcohol.
The less effect the alcohol will have on the individual.
The longer it will take to remove the alcohol from the body.

The body removes alcohol at a fixed rate. The more alcohol consumed, the longer it will take for the body to remove the alcohol from its system.

25. When driving on a wet road, you should reduce your speed by:
About one-half.
About one-third.
About one-quarter.

Reduce your speed when traveling on surfaces that provide reduced traction. Reduce your speed by about one-third when driving on a wet road.

26. If feeling drowsy while driving, you should:
Press on and finish the trip.
Drive faster to reach your destination more quickly.
Safely leave the road and take a nap.

If you begin to feel drowsy while driving, the best thing to do is to stop and get some sleep. A driver trying to push on and finish a trip while fatigued is a major cause of fatal accidents.

27. When leaving your vehicle:
The air brakes should be applied.
The parking brake should be applied.
Brakes should not be applied if the vehicle is left out of gear.

Parking brakes should be used whenever you park. If necessary, chock your wheels.

28. During the basic control skills test, you will receive points if you:
Pull up once.
Check your positioning.
Cross over exercise boundaries.

The examiner will score the number of times your vehicle touches or crosses an exercise boundary line. Each encroachment will count as an error, resulting in points against your skills test score.

29. When completing a conventional parallel parking maneuver, you should:
Back up past the parking space, then pull forward into it.
Pull forward past the parking space, then back into it.
Pull forward directly into the parking space.

You may be asked to complete a conventional parallel parking maneuver into a parking space that is to the right of your vehicle. You should drive past the parking space before backing into it while bringing the rear of your vehicle as close to the rear of the space as possible. Your vehicle should be completely within the boundaries of the space.

30. If your brakes fail while you are traveling downhill and there is no available escape ramp, you should:
Keep pumping the brakes.
Turn the vehicle off.
Drive into an open field.

If your brakes fail while you are driving downhill, you should first look for an escape ramp to stop your vehicle. If no ramp is available, you should look for an alternative place to bring your vehicle to a stop, such as an open field or side road that flattens out or turns uphill.

31. Rust around wheel nuts may mean:
It rained recently.
The nuts are loose.
The nuts are too tight.

It is important to inspect your tires before every drive. Rust around wheel nuts may indicate that they are loose.

32. The rods in S-cam brakes move the slack adjusters when air pressure is added to the brake chambers. This air pressure is added to the chambers when the driver:
Presses the brake pedal.
Uses the emergency brake.
Uses the trailer hand valve.

When pressing the brake pedal in a vehicle with S-cam brakes, air will enter the brake chambers. The added air pressure will push out the rods and move slack adjusters, twisting the brake camshafts.

33. Which of the following is acceptable if found during a pre-trip inspection?
Mismatched tire sizes
Tread of 3/32 of an inch in the grooves of the front tires
Tires manufactured by different makers

When inspecting your tires, verify that there is at least 4/32 of an inch of tread depth in every major groove on the front tires, and tread depth of at least 2/32 of an inch on the other tires. Tires on the same vehicle should all be the same size.

34. A commercial motor vehicle driver:
May use any cell phone while driving.
May only use a hands-free cell phone while driving, if permitted.
May only use a cell phone while driving on rural roads.

If you choose to use a mobile phone while operating a CMV, you may only use a hands-free mobile phone that is located close to you. However, even a hands-free mobile phone can be a dangerous distraction while driving. Make sure you are aware of all cell phone laws in the state in which you are driving.

35. To prevent your vehicle from rolling backward when beginning to move, you can:
Partly engage the clutch before taking your foot off the brake pedal.
Place the vehicle in second gear.
Use the parking brake when stopping.

To ensure that your vehicle does not roll backward when beginning to move after a stop, you should partly engage the clutch before removing your right foot from the brake pedal.
