Questions (124)
1. What is used to warn people about hazardous materials?
- Placards ✓
- Flashing lights
- Color-coded pieces of tape
- License plate stickers
Answer: A. Placards
Placards are used to warn people about hazardous materials. According to the handbook, placards are signs placed on the outside of a vehicle and on bulk packages to warn others about hazardous materials. They identify the hazard class of the cargo, and a placarded vehicle must carry at least four identical placards that are readable from all four directions. That directly matches the warning purpose asked about. The other choices are not described in the passages as the required way to warn people about hazardous materials.
2. Rollovers happen when drivers:
- Turn too quickly. ✓
- Do not driving fast enough.
- Pay attention to the road.
- Drive illegally.
Answer: A. Turn too quickly.
Rollovers happen when drivers turn too quickly. Section 6.1.1 puts it plainly: rollovers happen when you turn too fast, and it tells you to drive slowly around corners, ramps, and off ramps. It also explains that a higher center of gravity makes a truck easier to turn over, so cargo should stay low and centered. Section 2 adds that the sharper you turn, the greater the chance of a skid or rollover. That is why quick turning is the supported answer.
3. The person loading a tank with hazardous materials must be all of the following, except:
- Alert.
- Within 10 feet of the tank. ✓
- Aware of the hazards associated with the materials.
- Authorized to move the tank.
Answer: B. Within 10 feet of the tank.
The loader does not have to stay within 10 feet of the tank; the handbook requires the person to be within 25 feet. The passage on loading a cargo tank lists what the person must do: keep the tank in clear view, stay within 25 feet, know the material's hazards, know emergency procedures, and have permission and ability to move the tank. A 10-foot limit is not in that list; the stated distance is 25 feet. So the choice about staying within 10 feet is the one that does not match the handbook requirement.
4. Accelerating roughly is:
- Encouraged at slow speeds.
- Encouraged at all speeds.
- Discouraged, as it may cause damage to the vehicle. ✓
- Discouraged, as it may confuse other drivers.
Answer: C. Discouraged, as it may cause damage to the vehicle.
Rough or abrupt acceleration is discouraged because it can cause mechanical damage to the vehicle. The handbook says to speed up smoothly and gradually so the vehicle does not jerk. It warns that rough acceleration can cause mechanical damage, and when you are pulling a trailer it can damage the coupling. That is why the manual tells you to avoid it rather than encourage it, and why the answer pointing to possible vehicle damage is the right one. The advice about pulling a trailer makes the point stronger for combination vehicles.
5. During a static leakage test, the maximum leakage rate for a double combination vehicle is:
- 3 psi in one minute. ✓
- 6 psi in one minute.
- 8 psi in one minute.
- 4 psi in one minute.
Answer: A. 3 psi in one minute.
For a double combination vehicle, the maximum static air leakage rate is 3 psi in one minute. The handbook's static air leakage test starts with a fully charged system, the engine off, and the parking brake released, then has you watch the gauge for one minute. In that test, the loss should be less than two psi per minute for a single vehicle and less than three psi per minute for a combination vehicle. A double combination is still a combination vehicle, so the limit is 3 psi in one minute. The procedure where you hold the foot brake for a minute is a separate check with a different allowance.
6. Baggage and freight should be stored in a way that:
- Allows riders to exit by any door or window in an emergency. ✓
- Blocks an exit, if at least one other exit is available to passengers.
- Partially covers a door, since the items can be moved aside.
- Allows the cargo to be easily offloaded in an emergency.
Answer: A. Allows riders to exit by any door or window in an emergency.
Baggage and freight must be stored so passengers can still leave through any door or window in an emergency. The handbook's passenger-vehicle loading rules say secured baggage and freight must let riders get out through any door or window during an emergency. It also says not to leave carry-on bags in a doorway or aisle and to keep the aisle clear of things that could trip riders. A stored item that blocks an exit works against that exit rule, so keeping every exit usable is the correct choice.
7. 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.
8. At what psi is the safety valve set to open?
- 100 psi
- 150 psi ✓
- 200 psi
- 500 psi
Answer: B. 150 psi
9. When driving through a curve during the skills test, you should:
- Veer from your lane if needed to complete the curve.
- Reduce your speed after entering the curve.
- Refrain from looking for other vehicles while turning.
- Reduce your speed before entering the curve. ✓
Answer: D. Reduce your speed before entering the curve.
You should reduce your speed before entering the curve. The handbook's rule is to slow to a safe speed and shift into the right gear before the curve. That way you can use some power through the turn to keep the vehicle stable and can speed up once you are out. Another section adds that braking in a curve can lock the wheels and cause a skid, which is why the speed change belongs before the curve, not during it.
10. If turning to avoid a hazard:
- You should brake hard.
- You should not brake as it could cause the wheels to lock. ✓
- You should turn the wheel very sharply.
- You should hold down the brakes until you are past the hazard.
Answer: B. You should not brake as it could cause the wheels to lock.
When you turn to avoid a hazard, you should not brake, because braking while turning can lock your wheels. The handbook's quick-turn guidance says plainly: do not apply the brake while you are turning. It explains that wheels lock very easily during a turn, and if they lock you can skid out of control. The ABS section makes the same point from the other direction — locked steering wheels mean you lose steering control, while ABS lets you steer around an obstacle. So the safe habit is to keep your foot off the brake through the turn and hold the wheel tightly instead.
