Questions (22)
1. ____ is a thin layer of ice that forms on road surfaces.
- White ice
- Black ice ✓
- Green ice
- Blue ice
Answer: B. Black ice
Black ice is the thin layer of ice that forms on road surfaces. The handbook describes black ice as a thin, clear layer that lets you see the road underneath it, which makes the road look wet. It also says that when the temperature is below freezing and the road looks wet, you should watch for black ice. That matches the definition in the question. The other choices are not used in the handbook for this road condition.
2. 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.
3. To correct a drive-wheel braking skid, a driver should do all of the following, except:
- Remove your foot from the brake pedal.
- Turn quickly in the direction of the skid.
- Countersteer after the vehicle is back on course.
- Accelerate. ✓
Answer: D. Accelerate.
The action to leave out is accelerating; a driver correcting a drive-wheel braking skid should not accelerate. The handbook's correction steps for a drive-wheel braking skid are to stop braking so the rear wheels roll again, turn the steering wheel quickly, and counter-steer as the vehicle comes back on course. It also warns against over accelerating, over braking, and over steering, because those can cause a skid. Accelerating during the correction is therefore the action that does not belong.
4. 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.
5. During the skills test, if making a turn that requires a stop, you should:
- Skid to a stop.
- Stop after the stop line to get a better view.
- Allow your vehicle to roll.
- Keep the front wheels aimed straight ahead. ✓
Answer: D. Keep the front wheels aimed straight ahead.
When a turn requires you to stop, keep the front wheels aimed straight ahead while you are stopped. The on-road driving section of the handbook lists this as one of the things you must do during the skills test: do not let the vehicle roll, and keep the front wheels aimed straight ahead. It appears next to the rule about leaving a safe gap when you stop behind another vehicle. Keeping the wheels straight is also what the handbook's steering guidance points toward, since it wants your steering inputs small and the vehicle held in a straight line rather than drifting or turning while you sit still.
6. When entering a foggy area, you should:
- Stop on the side of the roadway.
- Pass other vehicles.
- Slow down. ✓
- Use your high beam headlights.
Answer: C. Slow down.
When you enter a foggy area, you should slow down. The handbook says fog is often unexpected and visibility can drop fast, so you should watch for it and be ready to reduce speed. Its specific instruction is to slow down before you enter the fog, and it warns you not to count on the fog thinning out once you are inside it. It also says the best choice is not to drive in fog at all, and if you must, to obey fog warning signs and use low-beam headlights and fog lights for the best visibility, even in daytime.
7. To make driving at night easier, you should:
- Keep your interior light turned on.
- Adjust the instrument panel lights as dimly as you can while still being able to read the gauges. ✓
- Not take a nap before driving.
- Use only your low beam headlights.
Answer: B. Adjust the instrument panel lights as dimly as you can while still being able to read the gauges.
Dim the instrument panel lights as low as you can while still reading the gauges. The handbook warns that a bright cab makes it harder to see outside at night, so it tells you to keep the interior light off and turn the instrument lights down as far as you can and still read the gauges. A dim panel keeps your eyes adapted to the dark road ahead, which is the whole point of the advice on that page.
8. Headlights:
- Are not usually necessary when driving at night.
- Provide better light than the sun.
- Should be on the high beam setting whenever possible. ✓
- Should always be on the high beam setting.
Answer: C. Should be on the high beam setting whenever possible.
9. Areas of the road that are shaded:
- Usually do not freeze.
- Usually do not contain moisture, so they can’t freeze.
- Will remain slick after ice on other areas of the road has melted. ✓
- Should always be avoided.
Answer: C. Will remain slick after ice on other areas of the road has melted.
Shaded areas of the road can stay icy and slick even after ice in open, sunny areas has melted. The handbook lists shaded areas as one sign of a slippery road. It says shady parts stay icy and slippery long after open areas have melted. That matches the choice saying these areas remain slick after other parts of the road clear. The point for a driver is that sunshine melting ice elsewhere does not mean the shaded stretch is safe, so lower speed and care are still needed there.
10. An air supply control in its "emergency" position will:
- Turn on the air supply.
- Apply the trailer emergency brakes. ✓
- Prevent a skid.
- Accelerate the vehicle.
Answer: B. Apply the trailer emergency brakes.
An air supply control in the "emergency" position applies the trailer emergency brakes. The handbook describes the trailer air supply control as the valve you use to manage the tractor protection valve. Pushing it in sends air to the trailer; pulling it out cuts that air off and sets the trailer emergency brakes. The same section says the emergency position is for shutting off the air and applying those brakes, while normal is for pulling a trailer. That matches the answer.
