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. Identification numbers, shipping names, and hazard classes:
Should be abbreviated on a shipping paper if a small piece of paper is being used.
Should be abbreviated on a shipping paper to make them easier to read.
Should not be abbreviated on a shipping paper.
Should only be abbreviated on a shipping paper if the abbreviations are easy to understand.

Identification numbers, shipping names, and hazard classes must never be abbreviated when listed on a shipping paper. The only exception to this is if the abbreviation is specifically authorized in the hazardous materials regulations.

2. 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.

3. On a slippery surface, stopping distance:
Is longer than on a regular driving surface.
Is not as long as on a regular driving surface.
Is about the same as on a regular driving surface.

A vehicle's regular stopping distance increases on slippery surfaces because there is less available traction.

4. Why are multi-speed axles and auxiliary transmissions used?
To make a vehicle operate more smoothly
To provide extra gears
To improve a vehicle's gas mileage

On many vehicles, multi-speed rear axles and auxiliary transmissions are used to provide extra gears.

5. 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.

6. To help control liquid surge, a driver should:
Make quick stops.
Decrease their following distance.
Brake rapidly.
Brake well in advance of a stop.

Drive vehicles with unbaffled tanks slowly and carefully, especially when stopping and starting. Brake well in advance of any stops and increase your following distance.

7. When a combination vehicle goes around a corner:
The turn should be made as tightly as possible.
The front and rear wheels move in different paths.
The rear wheels should run over the curb.
It is acceptable for street signs to be knocked over if they are too close to the road.

When a vehicle goes around a corner, the rear wheels follow a different path than the front wheels. This is called off-tracking. This effect is especially pronounced on vehicles with trailers.

8. A truck tractor built after March 1, 1997 must be equipped with:
An Anti-Lock Braking System (ABS).
A flag.
Hydraulic brakes.

Truck tractors with air brakes built on or after March 1, 1997 are required to be equipped with Anti-Lock Braking Systems (ABS).

9. After connecting the air lines to the trailer while coupling, you should:
Supply air to the trailer.
Chock the wheels.
Inspect the fifth wheel.
Connect the electrical cord.

Correctly following the steps to couple and uncouple trailers is vital to safely operating a combination vehicle. After connecting the air lines to the trailer while coupling, you should supply air to the trailer.

10. When inspecting your tires, you do not want to find:
Tire tread that is 4/32 of an inch deep.
Valve stems without damage.
Mismatched tire sizes.

There should be at least 4/32 of an inch of tread depth in every major groove on front tires and 2/32 of an inch on other tires. Valve stems should not be cut or cracked. Tire sizes should not be mismatched.

11. Shippers must keep a copy of shipping papers for:
Six weeks.
Six months.
One year.
Two years.

Shippers must retain a physical copy or an electronic image of hazardous materials shipping papers for a minimum of two years after the materials are accepted by the initial carrier. For hazardous waste, this increases to three years.

12. Joggers who are wearing headsets:
Are usually aware of what is happening around them.
May not be aware of what is happening around them.
Can clearly hear sounds of traffic.
Usually don’t have music playing.

Be careful around pedestrians, joggers, and cyclists who are wearing headphones. They may not be able to clearly hear surrounding traffic and may not be aware that you are there.

13. Rust around wheel nuts may mean:
It has rained recently.
The nuts could be loose.
The tires should be replaced.

Rust around wheel nuts may mean that they are loose. Check the tightness of the nuts if you see any rust in the area.

14. To know which placards to use, you need to know:
The hazard classes of the materials.
The types of containers holding the materials.
The destination.
The shipper.

To determine which hazardous materials placards to use, you must know the hazard class of the materials; the amount of hazardous materials being shipped; and the total weight of all classes of hazardous materials in the vehicle.

15. A vehicle that is smaller than your vehicle:
Will usually be able to stop faster than your vehicle.
Will usually take more time to stop than your vehicle.
Will take about the same amount of time to stop as your vehicle.

In general, a smaller vehicle will be able to come to a complete stop faster than a larger vehicle. Keep this in mind when determining your following distance.

16. What can happen if a parking brake is used in very wet weather when temperatures are below freezing?
The brakes will squeak.
The brakes may freeze so the vehicle cannot move.
The brakes may suddenly release by themselves.
The brakes may explode.

If you use the parking brakes when the weather is very wet and the temperature is below freezing, the brakes may become frozen, preventing the vehicle from moving.

17. If you are transporting Class 3 flammable liquids and your cargo needs to be moved into another tank, the flammable liquids:
May be transferred on the roadway as long as no other people are nearby.
Should not be transferred on a public road, unless under emergency circumstances.
Should be kept secret when they are being moved to another tank.
Should be transferred at night.

Flammable liquids should not be transferred from one vehicle to another on a public roadway, unless being moved due to an emergency. Always warn others of the hazards presented by the materials.

18. What do anti-lock brakes do?
Help a driver avoid wheel lockup
Lock up the front wheels
Prevent a vehicle from accelerating while traveling uphill
Prevent a vehicle from accelerating while traveling downhill

The function of an Anti-Lock Braking System (ABS) is to prevent the vehicle's wheels from locking up from hard brake application.

19. If turning to avoid a hazard:
You should brake hard.
You should not brake as it may cause the wheels to lock.
You should turn very sharply.

You should not brake while making a quick turn to avoid a hazard. Doing so could cause your wheels to lock and make your vehicle skid out of control.

20. When loading containers of hazardous materials, you should not use:

Always protect containers of hazardous materials. When loading hazardous materials, never use equipment that could damage containers or packaging, such as hooks.
