Questions (152)
1. Rollovers happen when:
- A truck driver is driving too fast. ✓
- The driver of a vehicle in front of a truck is moving to slowly.
- A truck driver is driving too slowly.
- ABS is working effectively.
Answer: A. A truck driver is driving too fast.
Rollovers happen when a truck driver is driving too fast, especially when turning too fast. The handbook says rollovers happen when you turn too fast, and it advises driving slowly around corners, ramps, and off ramps. It also notes that a higher center of gravity makes a truck easier to roll, and that driving too fast for conditions is a major cause of serious skids. So the key factor is excessive speed, not the speed of other vehicles or the ABS system.
2. Combination vehicles:
- Are usually shorter than single commercial vehicles.
- Usually require less skill to drive than single commercial vehicles.
- Usually require more skill to drive than single commercial vehicles. ✓
Answer: C. Usually require more skill to drive than single commercial vehicles.
3. The air storage tanks:
- Hold only enough air for one braking cycle.
- Hold enough air for brakes to be used several times if the compressor stops working. ✓
- Do not hold air unless there is an emergency.
- Hold enough air for more than 1,000 braking cycles.
Answer: B. Hold enough air for brakes to be used several times if the compressor stops working.
The air storage tanks hold enough air to let you use the brakes several times even if the compressor quits working. The handbook says air storage tanks are there to hold compressed air, and it states that they carry enough air for several brake applications after the compressor stops. That is the purpose described in the air brakes section, so the choice about several uses with a failed compressor matches the handbook. The number and size of tanks can differ from vehicle to vehicle, but the stated capability is repeated brake use, not a single cycle.
4. You may leave a vehicle that is carrying explosives unattended:
- Under a bridge.
- In a safe haven. ✓
- On the shoulder of a highway.
Answer: B. In a safe haven.
You may leave a vehicle carrying explosives unattended in a safe haven, which is an approved place for parking such vehicles. The handbook says you are allowed to leave your vehicle unattended in a safe haven. It defines a safe haven as an approved place for parking unattended vehicles loaded with explosives, and says local authorities usually designate these. That points to the safe haven as the permitted place for the situation in the question. The passages do not describe a bridge or a highway shoulder as an approved spot for leaving an explosives-loaded vehicle unattended.
5. While driving, you should:
- Develop plans to get out of any dangerous situation that could arise. ✓
- Enjoy the scenery.
- Never look at the mirrors.
- Focus on your own driving and not worry about other drivers.
Answer: A. Develop plans to get out of any dangerous situation that could arise.
6. To help prevent rollovers, you should:
- Accelerate quickly after stopping.
- Drive slowly around turns. ✓
- Keep the load near the back of the trailer.
- Keep the load on one side of the trailer.
Answer: B. Drive slowly around turns.
To help prevent rollovers, you should drive slowly around turns. The handbook's rollover section says that keeping the cargo low and driving slowly around turns are the two things that help prevent a rollover. It adds that rollovers happen when you turn too fast, and tells you to drive slowly around corners, on ramps, and off ramps. Turning slowly gives the tall, heavy vehicle less chance to tip over.
7. Regulations relating to hazardous materials are intended to protect:
- You.
- Those around you.
- The environment.
- All of the above. ✓
Answer: D. All of the above.
The hazardous materials regulations are meant to protect you, the people around you, and the environment. The handbook's section on the intent of the regulations says transporting hazardous materials can be risky and that the rules protect you, those around you, and the environment. It also explains that the rules tell shippers how to package materials safely and drivers how to load, transport, and unload them. Because the stated purpose covers all three groups, the answer that includes all of them fits the handbook. This is not a list where one item is the main concern and the others are secondary.
8. When a construction worker is close to the road, you should:
- Increase your speed.
- Decrease your speed. ✓
- Not drive in any lane.
- Wait to proceed until the construction is complete.
Answer: B. Decrease your speed.
9. If you must cross traffic while driving a combination vehicle, you should:
- Assume other drivers will make room for your vehicle.
- Wait for a gap large enough for your vehicle to safely cross. ✓
- Rely only on your mirrors.
Answer: B. Wait for a gap large enough for your vehicle to safely cross.
Wait for a gap large enough for your vehicle to safely cross. The handbook says large vehicles accelerate slowly and need more space, so the gap you would use in a car may not be enough. It also says to make sure you can get all the way across the road before traffic reaches you. That means you should judge the gap by whether your whole combination vehicle can clear the traffic flow safely, not by whether you can start moving.
10. A person who is watching the loading or unloading of a tank must do all of the following, except:
- Remain alert.
- Remain within 25 feet of the tank.
- Wear a chemical suit. ✓
- Know the hazards of the materials involved.
Answer: C. Wear a chemical suit.
