Questions (12)
1. Distracted drivers may be:
- Staying within their lanes.
- Traveling at consistent speeds.
- Preoccupied with using their cell phones. ✓
- Not talking to anyone else in their vehicles.
Answer: C. Preoccupied with using their cell phones.
Distracted drivers may be preoccupied with using their cell phones. The handbook tells you to watch for other drivers who are busy with things like maps, food, cigarettes, or a phone. It lists that kind of preoccupation as a sign of a distracted driver, along with drifting and uneven speed. That matches the choice about cell phone use. Recognizing distraction early helps you perceive and react in time to avoid a crash, and you should give that driver room.
2. If feeling tired and frequently yawning, you should:
- Press on and continue driving.
- Get some coffee.
- Drive faster.
- Pull over and take a nap. ✓
Answer: D. Pull over and take a nap.
You should pull over and take a nap. The handbook treats tiredness as a serious driving risk and says trying to push on is more dangerous than many drivers think, even a major cause of fatal accidents. When you notice signs of fatigue, it says to stop driving and either sleep for the night or take a short nap. Frequent yawning is a fatigue sign, so the right response is to stop and rest, not keep driving. The handbook also says caffeine may help for a short while but should not be relied on to prevent fatigue.
3. Which of the following is a sign of a potentially drunk driver?
- They are staying in their traffic lane.
- They are driving a consistent speed.
- They are stopping without a reason. ✓
- They have alcohol-related bumper stickers on their vehicle.
Answer: C. They are stopping without a reason.
A potentially drunk driver may stop without a reason. The handbook's night-driving section lists drunk drivers as a hazard and tells you to watch for certain clues. It says to look for drivers who have trouble staying in their lane, cannot keep a steady speed, stop for no reason, or show other signs of being under the influence. Stopping when there is no apparent reason fits that list. Staying in the lane and holding a consistent speed are the opposite of the listed warning signs, and bumper stickers are not part of the handbook's clues.
4. If you identify a distracted driver on the road, you should:
- Follow their vehicle closely.
- Try to get their attention.
- Give them plenty of room. ✓
- Flash your lights at them.
Answer: C. Give them plenty of room.
Give them plenty of room and keep your safe following distance. The handbook's section on watching out for distracted drivers says to give a distracted driver plenty of room and maintain your safe following distance. It also warns you to be very careful when passing, because the distracted driver may not know you are there and may drift in front of you. Keeping space around them means you have time to react if they drift over the lane divider, vary their speed, or move suddenly.
5. In cold weather, an alcohol evaporator should be checked and filled:
- Once a week.
- Every day. ✓
- Every hour.
- Once a month.
Answer: B. Every day.
Check and fill the alcohol evaporator every day during cold weather. The handbook says some air brake systems use an alcohol evaporator to put alcohol into the air system, which helps lower the chance of ice forming in valves and other parts in cold weather. Ice in the system can stop the brakes from working. For that reason, the cold-weather instruction is to check the alcohol container and fill it as needed each day. Daily air tank drainage is still required unless the system has automatic drain valves.
6. Fatigue:
- Has little effect on driving.
- Can impair driving. ✓
- Is not noticeable.
Answer: B. Can impair driving.
Fatigue can impair driving. The handbook describes fatigue as physical or mental weariness caused by strain, repetitive tasks, illness, or lack of sleep. It says that, much like alcohol and drugs, fatigue harms your vision and judgment. It also lists effects such as mistakes in speed and distance, slower recognition of hazards, and poorer critical decisions, and it says crash risk goes up. That makes fatigue a real driving impairment, not something minor or unnoticeable.
7. A fatigued driver:
- Is extra alert.
- Should take over-the-counter remedies to wake them up.
- May make critical decisions too slowly. ✓
- Is usually more conscientious than a typical driver.
Answer: C. May make critical decisions too slowly.
A fatigued driver may make critical decisions too slowly. The handbook describes fatigue as physical or mental tiredness from strain, repetitive tasks, illness, or lack of sleep. It says fatigue impairs your vision and judgment much like alcohol and drugs, and that it affects your ability to make critical decisions. It also slows how quickly you see and react to hazards and makes you more likely to misjudge speed and distance. So a tired driver does not simply feel sleepy; the thinking behind driving choices gets worse.
8. An open automobile window in cold weather may indicate that the driver is:
- Driving impaired. ✓
- Inappropriately dressed.
- Using the heat inside their vehicle.
- Enjoying the fresh air.
Answer: A. Driving impaired.
An open window in cold weather may mean the driver is driving impaired. The handbook puts an open window in cold weather in the same short list as speeding up or slowing down suddenly and driving too fast or too slow, right before it tells you to watch for drunk and sleepy drivers late at night. In that section the open window is treated as a clue about the driver's condition, not as a comfort choice, so the handbook answer is that it points to impairment. The passage does not explain the reason behind the clue, only that you should notice it.
9. Which of the following is not an example of a distracted person that motorists should be worried about?
- A driver talking to a passenger in their vehicle
- A child on the side of the road
- A construction worker on the side of the road
- A person sitting on a bench waiting for a bus ✓
Answer: D. A person sitting on a bench waiting for a bus
10. Which factor does not have an impact on a person’s blood alcohol concentration (BAC)?
- The number of alcoholic drinks consumed
- How quickly the alcoholic drinks were consumed
- The weight of the drinker
- The temperature of the drinks ✓
Answer: D. The temperature of the drinks
The temperature of the drinks does not affect a person's blood alcohol concentration; BAC depends on how much alcohol is consumed, how quickly it is consumed, and the drinker's weight. The handbook says BAC is set by the amount of alcohol you drink, the speed at which you drink it, and your weight. It also notes that what matters is the alcohol itself, not the type of drink it comes in. Drink temperature is not listed among the things that change BAC. That makes the temperature choice the one that does not have an impact.
