Questions (157)
1. If confronted by an aggressive driver, you should:
- Make eye contact to better communicate with them.
- Ignore their gestures. ✓
- Not move out of their path of travel.
Answer: B. Ignore their gestures.
Ignore their gestures. The handbook says to ignore gestures and refuse to react when an aggressive driver confronts you. The handbook's aggressive-driver section tells you to get out of the way first and to set your pride aside. It also says not to challenge the other driver by speeding up or trying to hold your lane. Finally, it says to ignore gestures and not react to them. That is why ignoring the gestures is the correct choice here.
2. Which of the following will not help prevent a rig from rolling over?
- Keeping the cargo as close to the ground as possible
- Driving slowly around turns
- Driving on the shoulder of a road ✓
Answer: C. Driving on the shoulder of a road
Driving on the shoulder of a road will not help prevent a rig from rolling over. The handbook says rollover risk goes up when the cargo's center of gravity is high. It names two things that help prevent rollover: keep the cargo as close to the ground as possible and drive slowly around turns. Driving on the shoulder is not listed as a rollover-prevention step. The shoulder passage describes it as an emergency escape route when you leave the road, not as a way to make a rig less likely to tip. So the shoulder choice is the one that does not help prevent rollover.
3. Hazardous materials shipping papers may not be kept:
- In a pouch on the driver’s door.
- In a pouch on the passenger’s side door. ✓
- Within reach of the driver while the seat belt is fastened.
Answer: B. In a pouch on the passenger’s side door.
Hazardous materials shipping papers may not be kept in a pouch on the passenger’s side door. The handbook lists where hazardous materials shipping papers must be kept so they can be found quickly: in a pouch on the driver’s door, within reach while your seat belt is fastened, or on the driver’s seat when you are out of the vehicle. A pouch on the passenger’s side door is not one of those listed locations, so it is the place where the papers may not be kept.
4. If one-fourth of the leaves in a leaf spring are missing when a vehicle is inspected:
- The vehicle’s driver will be allowed to drive, but only at reduced speeds.
- The vehicle will be put out-of-service until it is fixed. ✓
- The vehicle will be fine to drive since most of the spring is in place.
Answer: B. The vehicle will be put out-of-service until it is fixed.
The vehicle will be put out-of-service until the leaf spring is fixed. The handbook says that missing or broken leaves in any leaf spring are a defect, and when one-fourth or more of the leaves are missing, the vehicle is placed out of service. It also explains that inspectors who judge a vehicle unsafe put it out of service until it is fixed. One-fourth missing meets that threshold, so the vehicle cannot keep running until it is repaired.
5. When stopped, a bus driver should:
- Leave the bus.
- Warn exiting passengers about potential hazards. ✓
- Talk with another bus driver.
Answer: B. Warn exiting passengers about potential hazards.
6. When loading compressed gas, the liquid discharge valves should be:
- Closed.
- Removed.
- Opened. ✓
Answer: C. Opened.
When you are loading compressed gas, the liquid discharge valves should be opened. The compressed gas section says to keep the liquid discharge valves on the tank closed except when loading and unloading. That exception is what makes loading different from normal travel: during the transfer the valve is open, and once the loading is finished the valves go back to the closed position for the road. The tank vehicle section adds that you check the intake, discharge, and cut-off valves and make sure they sit in the correct position before loading, unloading, or moving the vehicle.
7. Before beginning a trip, you should:
- Leave the service line valve open.
- Remove the relay valves.
- Close the emergency line valve. ✓
Answer: C. Close the emergency line valve.
Before beginning a trip, close the emergency line valve; this is the step that follows checking air flow at the rear of the rig. The handbook's combination-vehicle air brake check has you open the emergency line shutoff valve at the back of the last trailer and listen for escaping air. That confirms the whole system is charged. After you hear it, you close the emergency line valve. You then open the service line valve to confirm service pressure reaches all trailers, and you close that valve too. The check depends on having air reach the rear so all brakes work, so the emergency valve is not left open after the test.
8. While driving, if you notice anything that affects safety or could lead to mechanical problems, you should:
- Wait to see if the problem goes away.
- Include the concerns in your written report. ✓
- Try to fix the issue yourself.
Answer: B. Include the concerns in your written report.
You should include the concerns in your written report. The handbook's after-trip inspection and report section says you may have to make a written report each day on the condition of the vehicles you drove. It directs you to report anything that affects safety or could lead to a mechanical breakdown. So when you notice a safety concern or possible mechanical problem, it belongs in that written report, not left to chance.
9. Class 1, Class 2.1, and Class 3 materials should not be placed in a trailer with:
- A heater. ✓
- An air conditioner.
- Other items.
Answer: A. A heater.
Class 1, Class 2.1, and Class 3 materials should not be placed in a trailer that has a heater. The handbook sets out a block of special Cargo Heater Rules and lists Class 2.1 flammable gas and Class 3 flammable liquids among the materials those rules cover. Elsewhere it says the rules usually forbid cargo heaters and warn against loading such products into a cargo space with a heater unless you have read all the related rules. For Class 1 explosives it adds a step-by-step precaution: shut the engine off, then disable the cargo heaters, disconnect their power sources, and drain their fuel tanks. The equipment those rules single out is the heater.
10. Rearward amplification refers to:
- The amount of noise projected to the rear of the vehicle.
- The cause of the "crack-the-whip" effect. ✓
- The number of trailers that can be pulled by one tractor.
Answer: B. The cause of the "crack-the-whip" effect.
Rearward amplification is the cause of the "crack-the-whip" effect. The handbook states plainly that rearward amplification causes the crack-the-whip effect. It explains this with a chart of combination vehicles in a quick lane change: the higher the rearward amplification number, the more likely the rear trailer is to roll over compared with the tractor. Triples, for example, are listed at 3.5. That is why the manual tells you to steer gently and smoothly, since a sudden steering move can tip a trailer over. So rearward amplification is the underlying cause, not a sound level or a trailer count.
