Questions (165)
1. 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.
Answer: A. Any risks of fire or explosion.
Emergency response information from the shipper must include any risks of fire or explosion. The handbook's minimum list of emergency response information includes risks of fire or explosion. The shipper must give the carrier information that can be used away from the vehicle to safely handle incidents with the material, and the required list names fire and explosion risks along with health hazards, precautions, fire-fighting methods, spill handling, and first aid. That makes fire and explosion risk part of what must be provided, not the material's value, the driver's details, or a count of responders.
2. How often do hazardous materials employees need to be trained?
- At least once a week
- At least once every three years ✓
- At least one every 10 years
Answer: B. At least once every three years
3. When refueling a vehicle transporting hazardous materials:
- The engine should be left on.
- The engine should be turned off. ✓
- The gas nozzle may be left unattended.
- Someone other than the driver should do it.
Answer: B. The engine should be turned off.
The engine should be turned off before you refuel a vehicle that contains hazardous materials. The hazardous materials section of the handbook says plainly to shut the engine down before fueling a motor vehicle carrying hazmat. The same sentence adds that someone has to stay at the nozzle and control the fuel flow the whole time. So the safe routine is: engine off, then fuel, with a person standing at the nozzle. Leaving the engine running while fuel is being transferred is exactly what the rule tells you not to do.
4. When loading compressed gas, the liquid discharge valves should be:
- Closed.
- Greased.
- 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 a compressed gas tank closed except when loading and unloading. That exception is what makes this question answerable: during the loading operation itself, the valves are open so product can move, and they go back to closed once loading or unloading is finished. The separate tank vehicle section also tells you to check the intake, discharge, and cut-off valves and confirm they are in the correct position before loading, unloading, or moving the vehicle.
5. If you are confronted by an aggressive driver, you should:
- Make eye contact.
- Ignore their gestures. ✓
- Try to race.
Answer: B. Ignore their gestures.
You should ignore the aggressive driver's gestures and refuse to react to them. The handbook says your first move is to get away from that driver if you can and not let pride drive your choices. It tells you not to challenge the person by speeding up or trying to hold your lane. Along with that, you should pay no attention to gestures and not respond to them. That is why ignoring the gestures is the correct action.
6. When entering or crossing traffic while driving a combination vehicle, it is especially important that you:
- Sound your horn.
- Make sure there is a large enough gap for your vehicle. ✓
- Expect other drivers to make room for your vehicle.
- Let other drivers wave you into their lane.
Answer: B. Make sure there is a large enough gap for your vehicle.
When entering or crossing traffic in a combination vehicle, make sure there is a large enough gap for your vehicle. The handbook explains that big vehicles accelerate slowly and need much more room than a car, and that the load affects acceleration, so you allow more room when heavily loaded. For doubles and triples it adds that these rigs are longer and cannot be turned or stopped suddenly, so you check for large enough gaps before entering or crossing traffic. Before starting across a road, you also need to know you can clear it before traffic reaches you.
7. When carrying a wide load, a driver should:
- Drive as fast as possible.
- Obtain special permits and follow special rules, such as driving only during certain times. ✓
- Honk at other drivers to get them to move from the nearest lane.
- Drive on the shoulder.
Answer: B. Obtain special permits and follow special rules, such as driving only during certain times.
8. When glad hands are coupled, the seals should be pressed together at an angle of:
- 30 degrees.
- 45 degrees.
- 60 degrees.
- 90 degrees. ✓
Answer: D. 90 degrees.
9. Slow down and be extra careful:
- When traveling in normal traffic.
- When driving on dry pavement.
- When approaching a work zone. ✓
Answer: C. When approaching a work zone.
Slow down and be extra careful when approaching a work zone. The handbook treats a work zone as a road hazard. It says people working on the road create a hazard, lanes may be narrower, curves sharper, or surfaces uneven, and other drivers may be distracted. It tells you to drive slowly and carefully near work zones and to warn drivers behind with flashers or brake lights. Another section says speeding in work zones is a leading cause of injury and death, so you should watch your speed and slow further when a worker is close.
10. An applicant will be denied a hazardous materials endorsement if they:
- Are a U.S. citizen.
- Are wanted for a misdemeanor.
- Are wanted for certain felonies. ✓
- Already have a driver license.
Answer: C. Are wanted for certain felonies.
An applicant will be denied a hazardous materials endorsement if they are wanted for certain felonies. The handbook says a hazardous materials endorsement can be denied or lost if you are wanted or under indictment for certain felonies. It lists this with other security-related disqualifiers, such as not being a lawful permanent resident or posing a security threat. The bank answer matches that wording. The passage does not say a misdemeanor or simply having a driver license blocks the endorsement.
