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 loading compressed gas, the liquid discharge valves should be:

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.

8. When traveling in heavy traffic, the safest driving speed is:
The posted speed limit.
The speed of surrounding traffic.
A speed much slower than the flow of surrounding traffic.

In heavy traffic, it is safest to match the speed of surrounding vehicles. Vehicles traveling in the same direction at the same speed are unlikely to collide. However, you should not exceed legal speed limits.

9. When backing with a trailer, turning toward the driver’s side is encouraged because:
The driver will have the best possible view.
Power lines should be on the passenger's side.
Other drivers can offer assistance on the passenger's side.

When driving in reverse, it is always recommended that a driver backs their vehicle toward its left side. This will allow the driver the best possible view of the rear of their vehicle.

10. A fatigued driver:
Is usually extra alert.
Is usually more conscientious than a typical driver.
May be slower to make critical decisions than a typical driver.

Fatigued drivers are slower to see or react to hazards than drivers who are not fatigued. Drivers are impaired in their ability to make critical decisions when they are driving drowsy.

11. A person attending a placarded vehicle may be:
In the sleeper berth.
Either awake or asleep inside the vehicle.
Within 100 feet of the vehicle.

A person attending a parked placarded vehicle must be either awake inside the vehicle or they must be within 100 feet of it. If not inside the vehicle itself, the person must have a clear view of the vehicle. The person attending may not be inside the sleeper berth.

12. When backing up, follow a turning trailer by:
Changing nothing. The vehicle will naturally follow the trailer.
Changing the direction of the steering wheel.
Turning the steering wheel even harder in the direction that it is already turning.

When backing with a trailer, begin by turning the steering wheel in the direction opposite of the turn. Once the trailer starts to turn, reverse the direction of the steering wheel to follow the trailer.

13. A person driving with an open window in cold weather may be:
A distracted driver.
A person who is dressed inappropriately.
A person who likes fresh air.

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 have their windows rolled down in cold weather.

14. While driving, gauges are:
To be monitored for potential signs of trouble.

While driving, you should watch your vehicle's gauges for signs of trouble. Be sure to inspect your gauges before beginning a trip to ensure that they are in proper working order.

15. 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.

16. When trying to control a minor truck fire, what should you do before opening trailer doors?
Check to see if the doors are hot.
Throw water on the doors.
Remove your protective equipment.

If you are experiencing a truck fire, you should not attempt to open trailer doors without first feeling the doors to see if they are hot. If the doors are hot, there may be a cargo fire. Leave the doors closed if there is a cargo fire.

17. When it’s difficult to see, such as at dawn or dusk, a driver can increase their vehicle's visibility by:
Driving while using their lights.
Driving with their windows open.
Flashing their lights periodically.

When driving at dawn, at dusk, or in inclement weather, you should use your headlights on their low beam setting to increase your visibility.

18. When backing a truck, you should:
Only use the side mirrors on the driver’s side of the vehicle.
Use both side mirrors.
Not use a helper.

When backing a truck, always use the mirrors on both sides of the vehicle. Have someone help you whenever possible.

19. Texting while driving is especially dangerous because:
It is both a mental and physical distraction.
A message may be upsetting to the driver.
People like to read and may become too engaged in their phones.

Texting while driving is particularly dangerous because it is both a mental and physical distraction to the driver. In addition to diverting a driver's mental attention away from the road, texting requires a person to remove at least one hand from the vehicle's controls.

20. A pre-trip inspection should include:
A check of the engine oil level.
Removing coolant.
Washing the tire rims.

When examining the engine compartment during a pre-trip inspection, you should check the engine oil level, the radiator coolant level, and the condition of the hoses.
