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 driving a tractor-trailer equipped with ABS, you should:
Stop harder than you would otherwise.
Use extra braking force to ensure the ABS kicks in.
Brake as you normally would.
Brake using less pressure than you would otherwise use.

When driving a tractor-trailer combination equipped with an Anti-Lock Braking System (ABS), you should brake in the same manner that you would in a vehicle without ABS.

2. If you are transporting explosives and your vehicle breaks down, you may notify other drivers:
With flares.
With electric lights.
By standing on the roadway and waving your arms.
By keeping the driver's side door open.

If your vehicle breaks down on the road while you are transporting explosive materials, you must warn other drivers. Put out warning signals like reflective triangles or electric lights if you are carrying Division 1.1, 1.2, or 1.3 explosives. Do the same if you are driving a tank used to transport Class 3 flammable liquids or Division 2.1 flammable gases, even if the tank is empty. If transporting flammable materials, do not use warning signals that could cause your cargo to catch fire.

3. An improperly placarded vehicle can only be moved:
To make room for other vehicles.
During an emergency.
If the vehicle will be traveling a distance shorter than 10 miles.
To wash the vehicle.

A vehicle must be properly placarded before it can be driven. A vehicle that does not display the proper placards may not be moved unless doing so is necessary to protect life or property in an emergency.

4. When transporting cargo, drivers must check the securement of the cargo every:
10 miles.
150 miles.
500 miles.
1,000 miles.

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.

5. Which of the following is not an indication of damaged brakes?
Cracked drums
Shoes with oil or grease on them
Shoes worn thinly
Pads free of oil or grease

Potential problems to check for when inspecting brakes include cracked drums; shoes or pads with oil, grease, or brake fluid on them; and shoes that are missing, broken, or worn dangerously thin.

6. When nearing a construction worker who is close to the road, you should:
Increase your speed.
Decrease your speed.
Not drive in any lane.
Wait until the construction is complete before proceeding.

When driving through work zones, you should make a particular point of reducing your speed when workers are on or near the road.

7. If transporting a package that contains radioactive materials, it is important to know that:
Radiation will pass through to other packages.
The package should be placed in the cab.
The package should be loaded on its side.
The package should be made of wood.

Radiation will surround each package of radioactive materials and pass through to all nearby packages. The number of packages that can be loaded together is controlled.

8. A pre-trip inspection:
Should never be completed the same way two times in a row.
Should always be completed in the same order.
Should only be done if it is sunny outside.
Should not be done if the driver thinks the vehicle is in good operating order.

A pre-trip inspection should be completed in the same way before every drive. Consistency will help you learn all of the proper steps and decrease the likelihood that you will forget to check something.

9. When you are driving while drowsy, you should:
Press on and try to finish the trip.
Take drugs to keep awake.
Stop and take a nap.
Stop for a coffee break.

The only effective way to deal with drowsiness while driving is to stop and sleep. Caffeine or other stimulant drugs may help you stay awake, but they will not keep you alert. You will likely end up being even more tired when the artificial stimulants begin to wear off.

10. When traveling with Division 1.1, 1.2, or 1.3 explosives, the vehicle should not be:
Parked within 300 feet of a bridge.
Parked within 40 feet of the road.
Parked for only short periods of time.
Parked on grass.

Except when parking briefly to perform necessary functions for vehicle operation (such as refueling), never park a vehicle carrying Division 1.1, 1.2, or 1.3 explosives within 300 feet of a bridge, tunnel, or building. Never park such a vehicle within five feet of the traveled portion of a road. Such vehicles should be parked only briefly.

11. If you are unsure if there is enough space for your vehicle to safely travel under a bridge, you should:
Speed up.
Swerve as you pass under the bridge.
Slow down.
Drive on the shoulder.

If you aren't sure that you have space for your vehicle to safely fit underneath an overhead object, slow down and seek an alternate route if possible.

12. Portable tanks:
Cannot be removed from a vehicle.
Are not permanently attached to a vehicle.
Are permanently attached to a vehicle.
Should not be used.

Cargo tanks remain on a vehicle at all times, regardless of whether or not they are carrying cargo. Portable tanks are bulk packaging and are not permanently attached to a vehicle.

13. If a truck is equipped, a trailer brake hand valve can be used to:
Add fuel to the vehicle.
Prevent the vehicle from rolling back when being started from a stop.
Check the oil level.
Load cargo.

If a tractor-trailer is so equipped, the trailer brake hand valve can be used to stop the vehicle from rolling back when being started from a stop.

14. Hydroplaning:
Only occurs at extremely high speeds.
Can occur at speeds as slow as 30 mph.
Happens most frequently when tire pressure is too high.
Happens most frequently when tires have good tread.

If there is enough water on the road, hydroplaning can occur at speeds as low as 30 mph. It is most likely if the tires' air pressure is too low or if tires' tread is worn.

15. When driving a bobtail tractor, you should be aware that:
Bobtails stop very easily.
Bobtails cannot drive as fast as tractors with semitrailers.
Bobtails are more difficult to stop than tractors with semitrailers.
Bobtails are illegal in most states.

Bobtail tractors are tractors that are not attached to any semitrailers. When operating a bobtail, you should be aware that stopping can be difficult and that it will take a longer distance to bring the bobtail to a complete stop than it would a tractor attached to a loaded semitrailer.

16. Emergency response information provided by the shipper must include:
Any risks of fire or explosion.
Value of the materials.
Driver information.
How many people should respond in the event of an accident.

At a minimum, emergency response information must include the basic descriptions and technical names of the materials being transported; immediate hazards to health; risks of fire or explosion; immediate precautions to be taken in the event of an accident or incident; immediate methods for handling fires; initial methods for handling spills or leaks in the absence of fires; and preliminary first aid measures.

17. On packages that are not large enough to hold a HazMat label, materials should be labeled:
With a barcode.
With a tag.
With a piece of orange tape.
With a red checkmark.

If a package of hazardous materials is not large enough to display the proper label, the label may be placed on a tag that is securely attached to the package.

18. When making a tight maneuver, you should:
Not use your mirrors, as they can be distracting.
Use your mirrors, but not too frequently.
Use your mirrors frequently.
Rely only on your mirrors.

Make a point of checking your mirrors often when making tight maneuvers.

19. The emergency air line:
Is controlled by the foot brake.
Is connected to the relay valves.
Supplies air to the trailer air tanks.
Prevents skids.

The emergency air line (also known as the supply line) has two functions. The first is to supply air to the trailer air tanks on a combination vehicle, and the second is to control the emergency brakes.

20. During the vehicle inspection test, you will be asked to:
Change a tire.
Explain to the examiner what you would inspect and why.
Estimate the weight of a load in a trailer.
Change a windshield wiper.

During the CDL vehicle inspection test, you must be able to inspect your vehicle and explain to the examiner what you are inspecting and why.
