Questions (28)
1. When carrying Division 1.1, 1.2, or 1.3 explosives, your vehicle should not be:
- Parked within 300 feet of a bridge. ✓
- Parked within 40 feet of the road.
- Driven in rain or snow.
Answer: A. Parked within 300 feet of a bridge.
You should not park within 300 feet of a bridge when carrying Division 1.1, 1.2, or 1.3 explosives. The handbook's parking rule for these explosives forbids parking within 300 feet of a bridge, tunnel, building, place where people gather, or open fire, except for short operational stops such as fueling. It also says never park within five feet of the traveled part of the road. That makes the bridge-distance choice the one that matches the rule. The passages do not set a 40-foot road distance and do not ban driving in rain or snow.
2. Rollovers are most likely to happen when:
- Drivers turn too fast. ✓
- Driver turn too slowly.
- It is windy.
- It is raining.
Answer: A. Drivers turn too fast.
Rollovers are most likely to happen when drivers turn too fast. The combination vehicles section states plainly that 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, which is why cargo should sit as low as possible. Turning too fast is the behavior the handbook names as the cause, so slowing down in turns is the prevention it teaches.
3. If an approaching driver is using their high beam headlights, you should:
- Look directly at the headlights.
- Flash your high beam lights to remind the driver to switch to their low beams.
- Look to the right side of your lane until the vehicle has passed. ✓
- Pull to the side of the road until the vehicle has passed.
Answer: C. Look to the right side of your lane until the vehicle has passed.
4. Of the following, which is the most slippery surface?
- Ice that is dry
- Ice that is wet ✓
- Wet pavement
Answer: B. Ice that is wet
Wet ice is the most slippery of the choices; the handbook says wet ice is much more slippery than ice that is not wet. The handbook lists melting ice as a sign of a slippery road. It explains that slight melting makes ice wet, and that wet ice is much more slippery than ice that is not wet. That directly supports choosing wet ice over dry ice. It also says wet roads can double stopping distance, so wet pavement is slippery too, but the handbook's direct comparison is between wet ice and ice that is not wet.
5. How much water must be on a road surface for a vehicle to hydroplane?
- Usually several inches
- A good amount, such as a large puddle
- A small amount ✓
- None
Answer: C. A small amount
6. If your vehicle is hydroplaning, you should:
- Use the accelerator.
- Not use the brakes. ✓
- Put the vehicle in a higher gear.
Answer: B. Not use the brakes.
7. Strong winds usually cause the greatest issues for:
- Lighter vehicles.
- Heavier vehicles. ✓
- Flatbed trailers.
Answer: B. Heavier vehicles.
8. The best way to recognize that your trailer has begun to skid is by:
- Seeing other drivers' faces.
- Seeing it in your mirrors. ✓
- Feeling it.
- Listening to the radio.
Answer: B. Seeing it in your mirrors.
The best way to catch a trailer skid early is by seeing it in your mirrors. The handbook's trailer skid procedure starts with recognizing the skid, and it says the earliest and best way to notice the trailer has started to skid is by watching it in your mirrors. It adds that whenever you brake hard, you should check the mirrors to confirm the trailer is staying where it belongs, because once the trailer swings out of your lane a jackknife becomes very hard to prevent. So the skill it teaches is a visual habit: hard braking means a mirror check.
9. Which of the following surfaces provides the least amount of traction?
- Ice that is dry
- Ice that is wet ✓
- Wet pavement
- Dry pavement
Answer: B. Ice that is wet
Wet ice provides the least traction. The handbook explains that slight melting makes ice wet, and once ice is wet it has far less grip than ice that stays dry. It also treats icy surfaces as the most serious case, telling drivers to slow to a crawl and stop as soon as they safely can. Wet pavement is slippery enough to stretch stopping distance and calls for a partial speed reduction, but the handbook does not rank it as bad as ice. Dry pavement is the normal surface used for comparison.
10. When driving at night, you should do all of the following, except:
- Make sure you are rested.
- Make sure your glasses are clean.
- Wear sunglasses. ✓
Answer: C. Wear sunglasses.
You should not wear sunglasses when driving at night. The night-driving section says to make sure you are rested and alert, and if you wear eyeglasses, to keep them clean and unscratched. It then says plainly not to wear sunglasses at night. So resting and clean glasses are recommended for night driving, while sunglasses are the one listed action you should not do. The passage gives the instruction directly and does not add a separate reason beyond it.
