Questions (26)
1. Shaded areas of a road:
- Usually don’t freeze.
- Are usually blocked from all moisture, so they cannot freeze.
- Will remain slick after ice has melted on other areas of the road. ✓
Answer: C. Will remain slick after ice has melted on other areas of the road.
Shaded areas of the road will remain slick after ice has melted on other areas. The handbook lists shady areas as one sign of a slippery road. It explains that these parts stay icy and slick well after exposed sections have thawed. That is why a shaded stretch can still be dangerous even when the rest of the road looks clear. The answer that says shaded areas stay slick after ice elsewhere has melted matches that warning.
2. When driving under wet conditions, a lack of spray coming from the tires of other vehicles indicates that:
- Ice has formed on the road. ✓
- The pavement is dry.
- The spray is caught on the underside of the vehicle.
Answer: A. Ice has formed on the road.
A lack of spray from other vehicles under wet conditions means ice has formed on the road. The handbook puts this under slippery-surface driving. It says to watch for ice, particularly on bridges and overpasses, and that when other vehicles throw no spray, ice has formed on the road. It also suggests checking your mirrors and wiper blades for ice, since ice there makes an icy road likely. So the missing spray is a warning sign to slow down and treat the surface as slippery, not a sign that the pavement is dry or that spray is trapped underneath.
3. You should specifically look out for black ice:
- When it is snowing.
- When the temperature is below freezing and the road looks wet. ✓
- When the temperature is above freezing and there is snow on the ground.
Answer: B. When the temperature is below freezing and the road looks wet.
Look out for black ice when the temperature is below freezing and the road looks wet. The handbook describes black ice as a thin, clear layer that lets you see the road underneath, so the pavement looks wet. It gives a specific warning: any time the temperature is below freezing and the road looks wet, watch for black ice. That matches the condition of below-freezing air plus a wet-looking road, not simply snowfall or above-freezing weather with snow on the ground.
4. Strong winds usually cause the greatest issues for:
- Lighter vehicles.
- Heavier vehicles. ✓
- Flatbed trailers.
Answer: B. Heavier vehicles.
5. If a vehicle begins to hydroplane, the driver should:
- Accelerate.
- Release the accelerator and push in the clutch. ✓
- Pull in the clutch and brake.
Answer: B. Release the accelerator and push in the clutch.
6. Water that has collected on a roadway can cause:
- Hydroplaning. ✓
- Acceleration.
- Stopping.
Answer: A. Hydroplaning.
Water collected on a roadway can cause hydroplaning. When water or slush collects on the road, the handbook says your vehicle can hydroplane. The tires lose contact with the road and have little or no traction, so you might not be able to steer or brake. Another passage says surfaces where water collects create the conditions for hydroplaning. That matches the answer: the collected water causes hydroplaning.
7. Black ice is:
- A thick layer of ice on the road.
- A thin layer of ice on the road. ✓
- Ice that is black from debris on the road.
Answer: B. A thin layer of ice on the road.
Black ice is a thin layer of ice on the road. The handbook describes black ice as a thin, clear layer that lets you see the road underneath it. Because it is clear, the road can look wet rather than icy. The manual warns that when the temperature is below freezing and the road looks wet, you should watch for black ice. That wording points to a thin layer, not a thick slab, and it has nothing to do with debris coloring the ice black.
8. In icy conditions, a retarder should be:
- Turned on.
- Turned off. ✓
- Only used on the rear wheels.
Answer: B. Turned off.
In icy conditions, the retarder should be turned off. The handbook warns that a retarder can make the drive wheels skid when they have poor traction. Because ice gives those wheels little grip, the safe action is to switch the retarder off whenever the road is icy, wet, or snow covered. The passage ties this directly to icy conditions, so the bank answer matches the handbook.
9. You are especially likely to encounter strong winds when:
- Coming out of tunnels. ✓
- Going into tunnels.
- Driving on shoulders.
Answer: A. Coming out of tunnels.
You are especially likely to meet strong winds when coming out of tunnels. The handbook's strong-wind section says strong winds make it hard to stay in your lane, and that this problem can be especially bad as you come out of a tunnel. That directly supports the answer. The passage does not tie the hazard to entering a tunnel or to driving on shoulders; it points to the moment you leave the sheltered tunnel and meet the wind.
10. Roads are especially slippery right after it begins to rain because:
- The water mixes with oil and grease on the road. ✓
- Tires are not made to drive in wet weather.
- The water yet hasn't absorbed the dirt and grease.
Answer: A. The water mixes with oil and grease on the road.
Roads are especially slippery right after rain begins because the water mixes with oil and grease left on the road. The handbook says that just after it starts to rain, water mixes with oil left on the road by vehicles, making the road very slippery. If rain continues, it washes the oil away. That oil-and-water film reduces traction, and the handbook notes that slippery roads make stopping take longer and turning harder without skidding. So the first rain is the risky time, before the oil has been washed off.
