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. When slowing down, you should ____ to warn other drivers
Use a turn signal
Sound your horn
Tap your brakes

Before slowing down, it can be a good idea to lightly tap your brakes. This will cause your brake lights to flash, providing a warning to motorists behind you.

2. Who is responsible for the safe operation of a vehicle?
The driver
The mechanic
The owner

The person driving a vehicle is responsible for its safe operation. Be sure to perform routine vehicle inspections before operating a commercial motor vehicle.

3. When a tank that is divided by bulkheads is being loaded with liquid cargo, most of the weight should be placed:
In the top of the tank.
In the middle of the tank.
In the rear of the tank.

When filling a tank that is divided by bulkheads, make sure that you do not place too much weight on the front or rear of the vehicle.

4. Slow down and be extra careful:
When traveling in normal traffic.
When driving on dry pavement.
When approaching a work zone.

Slow down and be especially careful when driving in and around work zones, in places where the pavement drops off sharply at the edge of the road, when foreign objects are present on the road, and on freeway on- and off-ramps.

5. How much water must be present 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.

6. 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.

7. When should mirrors be adjusted?
Before driving
While driving
After driving

The adjustment of your mirrors should be checked prior to the start of all trips. Adjust your mirrors as needed.

8. What does an Anti-Lock Braking System (ABS) do?
It allows a vehicle's wheels to lock up.
It prevents a vehicle's wheels from locking up.
It makes turning a vehicle easier.

An Anti-Lock Braking System (ABS) helps prevent wheel lockup during hard braking. If ABS detects impending lockup, it reduces braking pressure to a safe level.

9. You are especially likely to encounter strong winds when:
Coming out of tunnels.
Going into tunnels.
Driving on shoulders.

Strong winds can make it difficult to keep a vehicle in its proper lane. Strong wind can be a particular problem when a vehicle is being driven out of a tunnel.

10. If a vehicle is equipped with an Anti-Lock Braking System (ABS), when the vehicle is started:
The brakes should lock up.
The ABS indicator light should turn on, then quickly shut off.
The steering wheel will not move until the air tanks are full.

After starting the engine of a vehicle equipped with an Anti-Lock Braking System (ABS), the indicator light should come on and then turn off. If the light stays on, something is wrong with the ABS.

11. If a driver stops and leaves their vehicle while transporting hazardous materials, the shipping papers should be:
Carried by the driver.
Left in the front seat of the cab.
Placed in a box under the passenger seat.

If a driver stops and exits their vehicle, the hazardous materials shipping papers must be left on the driver's seat.

12. When filling a tank that has been separated by bulkheads, most of the weight should be in the:
Front of the tank.
Middle of the tank.
Rear of the tank.

When filling a tank that is divided by bulkheads, you must pay particular attention to weight distribution. Avoid putting too much weight on the front or rear of the tank.

13. Hydroplaning:
Rarely occurs with large trucks.
Usually happens when vehicles are traveling faster than 65 mph.
Can occur with a minimal amount of water on the roadway.

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 a large amount of water on the road for this to occur.

14. When loading compressed gas, the liquid discharge valves should be:
Closed.
Greased.
Opened.

Keep liquid discharge valves on a compressed gas tank closed except when loading and unloading.

15. If loading corrosive materials, you should not:
Roll the containers.
Load the containers by hand.
Use the vehicle’s parking brake.

If loading by hand, load breakable containers of corrosive liquid one by one. Keep them facing upright. Do not drop or roll the containers.

16. Pushing in the trailer air supply control will:
Supply the trailer with air.
Deactivate the air brakes.
Prevent the vehicle from skidding.

Push in the trailer air supply control to supply the trailer with air. Pull out the trailer air supply control to turn off the air supply and activate the emergency brakes.

17. The trailer hand valve:
Should always be used for parking.
Should only be used for parking on a downgrade.
Should never be used for parking.

Never use the trailer hand valve while parking because doing so may release the air pressure from the braking system, releasing the brakes that are holding the vehicle in place. Instead, use the parking brake or wheel chocks.

18. As part of the vehicle inspection test, a CDL applicant will be asked to:
Check the engine oil level.
Replace a tire.
Remove the alternator belt.

The vehicle inspection test will include a check of the oil level. You must show that it is within a safe operating range.

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

The main factors that determine a person's blood alcohol concentration (BAC) are how much alcohol has been consumed, how quickly it was consumed, and the person's body weight.

20. A CDL will be disqualified for:
Two convictions of violating hand-held mobile telephone use laws.
A driver listening to the radio too loudly.
Turning right at a red stoplight.

A CDL will be disqualified after two or more convictions of violating hand-held mobile telephone use laws while operating a CMV.
