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. Having ABS on only one axle:
Can be dangerous.
Still allows you additional control when braking.
Slows the vehicle, but cannot stop it.

If you have an Anti-Lock Braking System (ABS) equipped on only the tractor, only the trailer, or only one axle, you will still have more control over the vehicle when braking than you would without ABS. You should brake normally.

2. Emergency equipment in a vehicle is:
Only required for vehicles that are transporting hazardous materials.
Only required during interstate travel.

During a pre-trip inspection, you should check for emergency equipment, including spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

3. When taking a driving test:
You must supply the same type of vehicle for which you will require a CDL.
You may supply any type of vehicle, even if it is not the type of vehicle for which you will be using with the CDL.
The testing station will supply the vehicle.

Skills tests must be taken in the type of vehicle the applicant plans to drive. The applicant is generally responsible to supply the testing vehicle.

4. How can a driver maintain alertness while driving?
Stay fit and healthy
Keep the cab warm
Eat heavy foods

Eating heavy foods before driving or keeping the temperature in a cab too high can cause a driver to become drowsy while behind the wheel. Exercising and maintaining a healthy diet will help a driver to stay alert while driving.

5. By beginning a left turn before reaching the center of an intersection, you:
Will likely complete the turn satisfactorily.
May hit other vehicles with the left side of your vehicle.
Can expect other drivers to move their vehicles to accommodate your turn.

When planning to turn left at an intersection, make sure you have reached the center of the intersection before beginning the turn. If you turn too soon, off-tracking may cause the left side of your vehicle to hit another vehicle.

6. When near a railroad crossing:
You should expect to hear every approaching train.
You may not hear a train, even if one is approaching.
You will hear two short blasts of a train's horn if a train is approaching.

You should never assume that you will hear an approaching train. The train operator may fail to sound the horn, or the use of a train's horn may be prohibited in a specific area. Even if the train does sound its horn, noise from inside your own vehicle may prevent you from hearing the train until it is dangerously close.

7. If convicted of a traffic violation in your personal car:
You must tell your employer.
Your CDL will not be affected.
Law enforcement will tell your employer.

If you are convicted of any traffic violations while driving any vehicle, you must notify your employer within 30 days of the conviction. This rule excludes parking violations.

8. When starting the engine of a truck with a trailer, you can tell that your vehicle's ABS is not working if:
The yellow light on the left rear of the trailer stays on.
The red light on the right side of the trailer flashes three times.
All the rear lights flash and then turn off.

When turning on your vehicle's engine, the lights on the dash should come on and then turn off. If the ABS malfunction light stays on, the system is not working properly. In the case of a truck with a trailer, if the yellow light on the left rear of the trailer stays on once the engine has been started, the system is not working properly.

9. When stopping in an emergency situation, you should:
Veer your trailer to the right and stop.
Stop in a straight line.
Veer your trailer to the left and stop.

If you need to make an emergency stop, you can use either the controlled braking method or the stab braking method. It's important to brake in a way that keeps your vehicle in a straight line but will still allow you to turn if necessary.

10. When approaching a vehicle for a pre-trip inspection, a driver should look under the vehicle:
To see if the vehicle is on an incline.
To see if there are any fresh fluids on the ground.
To see if the vehicle is in a parking spot.

When approaching your vehicle before an inspection, make note of its general condition and ensure that it is not damaged or leaning. Look under the vehicle for fresh leaks of oil, grease, or fuel. Check around the vehicle for hazards to movement, such as people, other vehicles, or low-hanging wires or tree limbs.

11. When should you slow for a curve?
Before entering the curve
While in the curve
After the curve

You should always slow to a safe speed before entering a curve. Slowing while within the curve could cause a skid.

12. Dry bulk tanks:
Usually have a low center of gravity.
Usually have a high center of gravity.
Are usually not allowed to cross railroad tracks.

Driving with dry bulk tanks requires special care because they usually have high centers of gravity. It is also important for drivers to be prepared for the contents to shift in transit.

13. When applying your brakes, the vehicle should:
Pull to one side.
Not pull to either side.

Your vehicle pulling to one side or the other while you are braking can indicate trouble with the brakes.

14. If being tailgated, you should:
Increase your speed.
Increase the amount of space between your vehicle and the vehicle in front of you.
Make quick movements.

If you are being tailgated, you should increase the distance between your vehicle and the vehicle ahead of you. This reduces the need for you to make sudden changes in speed or direction while making it easier for the tailgater to pass your vehicle.

15. A slack adjuster should move no more than ____ from where it is attached to the push rod.
Two inches
Five inches
One inch

Before a trip, you should check each slack adjuster after parking, setting wheel chocks, and disengaging the parking brake. Pull the slack adjusters to make sure that they do not move more than about one inch from where the push rod is attached. If they move more than one inch, they may be out of adjustment and will need to be fixed.

16. During a basic vehicle controls skills test exercise, your vehicle's final position should be:
In the general area that was described by the examiner.
In the exact final position described by the examiner.
Within three feet of the final position described by the examiner.

You should finish each exercise with your vehicle in the exact position described by the examiner. You can be penalized for failing to complete an exercise exactly in the manner described by the examiner, potentially resulting in failure of the basic control skills test.

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

When inspecting a trailer coupling, you should make sure the fifth wheel locking jaws are closed around the shank of the kingpin, not the head of the kingpin.

18. Which of the following is not a warning sign of fatigue?
Difficulty focusing
Staying within your lane
Rubbing your eyes

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.

19. If the safety relief valve in the air brake system releases air:
The compressor needs more air.
There is something wrong with the brakes.
You may continue driving.

An air brake system has a safety relief valve, which releases air from the tanks if the pressure gets too high. If the valve must operate, something in the system is wrong and should be addressed by a mechanic.

20. For a hazardous materials endorsement, an applicant will be required to:
Provide their fingerprints and undergo a background check.
Provide employment history from the last five years.
Provide a list of countries visited within the last 10 years.

To obtain a hazardous materials endorsement, you must submit your fingerprints and pass a background check.

21. To stay alert while driving, you should:
Eat a heavy meal before beginning your trip.
Keep the cab warm.
Ride with a second person who can share driving responsibilities.

Splitting driving responsibilities with a second driver lowers the chance that either of you will drive while fatigued. You can also reduce the risk of fatigue by avoiding heavy foods and keeping the interior of the cab cool.

22. Brakes out of adjustment will:
Work properly.
Cause some of the brakes to overwork and malfunction.
Allow better acceleration.

Brakes out of adjustment will fade before those that are properly adjusted. Brake adjustment must be checked frequently to help prevent brake issues.

23. Items on a flatbed:
Are usually heavy enough to not need to be strapped down.
Should not be strapped down if you are driving more slowly than 35 mph.
Must always be secured.

On flatbed trailers and trailers without sides, cargo must be tied down to prevent it from shifting or falling off in transit.

24. An application pressure gauge shows:
How much air pressure is being applied to the brakes.
How much air pressure is available.
How much air pressure is required to stop a vehicle.

If a vehicle is equipped, an application pressure gauge shows how much air pressure is being applied to the brakes. This gauge can help a driver identify if their brakes are beginning to fade.

25. 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.

26. 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.

27. 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.

28. A driver who stops at a green light could be:
An impaired driver.
A driver who is color blind.
A person who does not know the rules of the road.

It is important to observe other drivers' actions and identify clues that a person could be driving impaired. Drivers who have had too much to drink, are sleepy, are on drugs, or are ill can present hazards to other drivers. One sign that a driver may be impaired is that they stop in inappropriate places, such as at green traffic lights.

29. Drowsy driving is most common during:
The night.
The early morning.
The mid-afternoon.

Drowsy driving is most common during the night because people are naturally prone to be less alert in the hours during which they are normally asleep. If you must drive at night, take every precaution to prevent fatigued driving.

30. Rough acceleration:
Is a good way to stay awake on long trips.
Is distracting.
Can cause mechanical damage.

Rough acceleration can cause mechanical damage, so be sure to accelerate smoothly and gradually.

31. What is often found in compressed air?
Brake fluid

Compressed air in an air brake system usually contains a certain amount of water and compressor oil. The water and oil can damage the brakes if left to accumulate in the system. Tanks must be drained regularly to remove this build-up.

32. When in heavy traffic, the safest driving speed is:
Slower than the speed being driven by surrounding traffic.
The same speed being driven by surrounding traffic.
Faster than the speed being driven by surrounding traffic.

In heavy traffic, it is safest to travel at the same speed as other vehicles. If two vehicles continue to drive in the same direction at the same speed, they cannot hit each other.

33. Which of the following is not a cause of hydraulic brake failure?
Loss of hydraulic pressure
Brake fade on long hills

Most cases of hydraulic brake failure come from one of two causes. The brakes may fail due to a loss of hydraulic pressure or due to overuse on long hills, causing the brakes to fade.

34. If an air compressor is belt-driven, the belt should be routinely checked to ensure that it is:
Properly tightened.

If your vehicle has air brakes, the air compressor drive belt should be checked before each drive. Check the tightness of the belt and verify that it is in good condition.

35. Rolling backward when beginning to accelerate is dangerous because:
The transmission may be damaged.
The truck is not made to go backwards.
You may hit a vehicle behind you.

Be sure that you are able to accelerate without first rolling back. Rolling backwards may cause you to collide with a vehicle or other obstacle behind your truck.
