Passing Score 16

1. When loading compressed gas, the liquid discharge valves should be:

Closed.

Removed.

Opened.

On a compressed gas tank, liquid discharge valves must always be kept closed, except during loading and unloading.

2. 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.

3. A broken exhaust system:

Can allow poisonous fumes to enter the cabin.

Does not cause problems.

Should not be a concern.

A broken exhaust system can let poisonous fumes into a vehicle's cab or sleeper berth. Be sure to inspect your exhaust system for any loose, broken, or missing parts.

4. A jogger wearing a stereo headset:

Is probably aware of what is happening around them.

May not be aware of what is happening around them.

Can hear the sounds of traffic.

Be careful around pedestrians, joggers, and cyclists who are wearing headphones. They may be unable to hear your vehicle approaching and may do dangerous things because they do not know you are there.

5. 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.

6. When traveling with Division 1.1 explosives, you must park at least ____ from any building.

25 feet

50 feet

300 feet

When carrying Division 1.1, 1.2, or 1.3 explosives, do not park within 300 feet of a bridge, tunnel, or building; a place where people gather; or an open fire.

7. If cargo containing hazardous materials is leaking but the driver does not have access to a phone, they should:

Drive to a phone to alert emergency personnel.

Drive to a designated hazardous materials clean-up facility.

Send someone else for help.

If a cargo of hazardous materials begins to leak, do not move your vehicle any more than safety requires. If you continue to drive, an even larger area will become contaminated. Instead, you should park your vehicle, secure it, stay with the vehicle, and contact the proper emergency personnel. If you do not have access to a phone, you should send someone else to get help.
