Questions (13)
1. Which of the following is not a sign of a driver becoming tired?
- Frequent blinking
- Drifting from their lane
- Feeling hungry ✓
Answer: C. Feeling hungry
Feeling hungry is not a sign of a driver becoming tired. The handbook's list of fatigue warning signs includes drifting from your lane, following too closely, hitting a shoulder rumble strip, feeling restless and irritable, and trouble remembering the last few miles. Hunger does not appear on that list. The handbook tells you to treat these warning signs seriously: if you notice any signs of fatigue, stop driving and sleep for the night or take a 15 to 20 minute nap. Feeling hungry is a normal body signal about food, not a fatigue warning.
2. Which of the following is not a type of distraction?
- Physical
- Mental
- Obtuse ✓
Answer: C. Obtuse
Obtuse is not a type of distraction. The handbook says a distraction is anything that takes your attention away from driving, and it gives examples such as talking to passengers, adjusting controls, eating or drinking, texting, and daydreaming or being occupied with other mental distractions. Those examples include physical actions and mental attention. The handbook never lists obtuse as a distraction category, and nothing in the passage ties that word to something that pulls your attention from driving.
3. A distracted driver:
- Usually follows the rules of the road.
- Usually has slowed perception. ✓
- Is a good person to follow.
Answer: B. Usually has slowed perception.
A distracted driver usually has slowed perception. The handbook lists slowed perception as one effect of distracted driving. It explains that this can make a driver late to notice, or miss entirely, something important happening in traffic. The same section also mentions delayed decisions and wrong inputs to steering, accelerator, or brakes. Because the manual ties distraction to slowed perception, the statement about slowed perception fits.
4. When driving, you should stop every ____ to take a break to avoid becoming too tired.
- Half hour
- Two hours ✓
- Six hours
Answer: B. Two hours
You should stop about every two hours during a long trip to take a break. The handbook's list of ways to stay alert behind the wheel includes taking periodic breaks, roughly every 100 miles or 2 hours on long trips. It also warns that pushing on while tired is more dangerous than most drivers realize. A two-hour break interval fits that guidance directly, while the other intervals listed in the choices do not appear anywhere in the handbook's fatigue advice.
5. When experiencing cold weather, be sure to check your vehicle's alcohol evaporator:
- Every three hours.
- Every day. ✓
- Every other week.
Answer: B. Every day.
6. If feeling drowsy while driving, you should:
- Press on and finish the trip.
- Drive faster to reach your destination more quickly.
- Safely leave the road and take a nap. ✓
Answer: C. Safely leave the road and take a nap.
The correct move is to safely leave the road and take a nap. If you feel drowsy, the handbook's alertness guidance says to pull over and rest or nap. It also warns that trying to push on while tired is more dangerous than many drivers realize and is a major cause of fatal crashes. When fatigue signs appear, it tells you to stop and sleep for the night or take a short nap. That makes leaving the road safely the proper response.
7. While still below the legal limit, a driver operating a CMV with a detectable amount of alcohol in their system will:
- Result in an out-of-service order for two hours.
- Result in an out-of-service order for 10 hours.
- Result in an out-of-service order for 24 hours. ✓
Answer: C. Result in an out-of-service order for 24 hours.
Any detectable amount of alcohol under .04% puts you out of service for 24 hours. The handbook states that a CMV driver with any detectable amount of alcohol under .04% is placed out of service for 24 hours. That covers the situation in the question: you are still under the legal limit, but alcohol shows up. The rule ties the length of the out-of-service period to the presence of any alcohol at all, not to how far below the limit you are, so the 24-hour figure is the one that applies.
8. Texting while driving is especially dangerous because:
- It is both a mental and physical distraction. ✓
- A message may be upsetting to the driver.
- People like to read and may become too engaged in their phones.
Answer: A. It is both a mental and physical distraction.
Texting while driving is especially dangerous because it is both a mental and physical distraction. The handbook says texting makes you look at a small screen and work the keypad with your hands. That takes your eyes and hands away from driving, while your mind is also busy with the message. The handbook calls this a physical and mental distraction happening at the same time. It also says texting is riskier than talking on a cell phone for this reason. That combination is what makes texting especially dangerous, so the answer that names both kinds of distraction fits the handbook.
9. Drowsy driving is most common during:
- The night. ✓
- The early morning.
- The mid-afternoon.
Answer: A. The night.
Drowsy driving is most common at night, so the correct choice is the one naming the night. The handbook says drowsy-driving crashes tend to happen when sleepiness is strongest, and it names the night and the mid-afternoon as those times. It then explains that most people are less alert at night, particularly after midnight, and that drivers who drive at night are much more likely to have fall-asleep crashes. That reasoning points to night as the time when drowsy driving is most common, which is what the question asks for.
10. Alcohol can be removed from your system:
- By exercising.
- By drinking coffee.
- By waiting. ✓
Answer: C. By waiting.
Alcohol can be removed from your system only by waiting. The handbook explains that alcohol enters the bloodstream and is processed by the liver at a fixed rate. It says the liver handles only a small amount per hour, so the process cannot be rushed. The passage specifically says that time, not black coffee or a cold shower, will sober you up. That makes waiting the only listed way for alcohol to leave your system. The handbook does not mention exercise as a way to remove alcohol, and it directly rules out coffee as a sober-up method.
