Questions (17)
1. A sign indicating a maximum safe speed:
- Is suggesting a driving speed, but vehicles may travel faster than the posted speed.
- Is suggesting a speed limit to be followed only by vehicles weighing more than 26,000 pounds.
- Should be followed and no vehicle should travel faster than the posted speed. ✓
- Is only applicable to automobiles.
Answer: C. Should be followed and no vehicle should travel faster than the posted speed.
A sign indicating a maximum safe speed should be followed, and no vehicle should travel faster than the posted speed. The handbook says that when there is a sign indicating "Maximum Safe Speed," you should never exceed the speed shown. It treats that sign as a speed you must stay at or below, not as a casual suggestion. So the safe and proper action is to follow the posted maximum safe speed and not go faster than it.
2. When traveling more slowly than 40 mph, maintain at least ____ of following distance per every 10 feet of your vehicle.
- One second ✓
- Two seconds
- Three seconds
- Four seconds
Answer: A. One second
3. About how many seconds in advance of a bus stop should warning lights be activated?
- One to two seconds
- Two to four seconds
- Five to ten seconds ✓
- 45 seconds
Answer: C. Five to ten seconds
4. Trailers with low underneath clearance may be difficult to drive:
- On interstate highways.
- Over railroad crossings. ✓
- On dirt roads.
- At the posted speed limit.
Answer: B. Over railroad crossings.
Trailers with low underneath clearance can be hard to drive over railroad crossings, where the trailer may get hung up on the tracks. The handbook points to railroad crossings as a special problem for trailers that sit low to the ground. It warns that you should not gamble on getting hung up halfway across the tracks. The clearance between the trailer's underside and the road surface is what matters at the raised rails and crossing surface, and that same warning appears both in the driving safely section and in the combination vehicles section, so the risk is tied to crossings rather than to open highway driving.
5. One way to avoid jackknifing is to:
- Swerve frequently.
- Exceed the speed limit.
- Look ahead of your vehicle to identify potential hazards. ✓
- Drive on the shoulder.
Answer: C. Look ahead of your vehicle to identify potential hazards.
6. A curve's posted design speed is:
- Safe for buses.
- Safe for all vehicles, including buses.
- The minimum speed at which the curve should be driven.
- Not always safe for buses. ✓
Answer: D. Not always safe for buses.
A curve's posted design speed is not always safe for buses. The handbook says every banked curve has a safe design speed, and in good weather the posted speed is safe for cars. It may be too high for many buses. With good traction a bus may roll over; with poor traction it may slide off the curve. That is why you reduce speed for curves and treat the posted number as a car benchmark, not a guarantee for your bus. Another section adds that high-center-of-gravity trucks can roll over at a curve's posted speed limit.
7. How does doubling your speed from 20 mph to 40 mph affect your vehicle's braking distance?
- It stays about the same.
- It increases slightly.
- It doubles.
- It quadruples. ✓
Answer: D. It quadruples.
Doubling your speed from 20 mph to 40 mph makes the braking distance four times longer. The handbook's stopping-distance figure says that when you go from 20 to 40 mph, the impact is four times greater and the braking distance is also four times longer. So the increase is not a small change or just double; it is four times the distance. The same passage shows the pattern continues at higher speeds, which reinforces that speed has a strong effect on braking distance.
8. The Individual Vehicle Distance Record (IVDR) must include all of the following, except:
- The date of trip.
- The route of travel.
- The total distance traveled.
- The number of stops. ✓
Answer: D. The number of stops.
9. A driver should always:
- Stay in the right lane.
- Have an emergency plan. ✓
- Stay in the left lane.
- Drive faster than the posted speed limit.
Answer: B. Have an emergency plan.
A driver should always have an emergency plan. The handbook's defensive driving section tells you to keep scanning for hazards, but it also explains the reason you scan: hazards can turn into emergencies, and spotting them early gives you time to plan a way out. When you see a hazard, you should think about what could develop and decide what you would do, then be ready to act on that plan. The book calls this being a prepared, defensive driver who improves safety for yourself and everyone else on the road.
10. If braking at a speed of 55 mph while driving on dry pavement, the brake lag can add ____ to your vehicle's total stopping distance.
- 32 feet ✓
- 15 feet
- 50 feet
- 10 feet
Answer: A. 32 feet
Brake lag at 55 mph on dry pavement adds about 32 feet to your total stopping distance. The handbook explains that with air brakes there is a delay called brake lag, the time it takes for air to move through the lines and reach the brakes after you push the pedal. Because of that delay, the vehicle keeps rolling a little before the brakes actually work. The handbook puts that added lag distance at roughly 32 feet when you are going 55 mph on dry pavement, and it lists brake lag distance as one of the four pieces of total stopping distance.
