Questions (13)
1. If you are feeling tired and yawning a lot while you are driving, you should:
- Pull over and take a nap. ✓
- Get some coffee.
- Drive faster.
Answer: A. Pull over and take a nap.
You should pull over and take a nap. Yawning a lot is a sign of fatigue, and the handbook says to stop driving when you notice any sign of fatigue. It tells tired drivers to sleep for the night or take a short nap of about 15 to 20 minutes. The handbook also says forcing yourself to continue when tired is more dangerous than many people realize and is a major cause of deadly crashes. So the safe action is to get off the road and rest, not to keep driving.
2. What eliminates alcohol from the bloodstream?
- Coffee
- Exercise
- Time ✓
Answer: C. Time
Time is what eliminates alcohol from the bloodstream. The handbook explains that alcohol goes into the bloodstream and the liver processes it at a fixed rate—only one-third of an ounce per hour, less than a standard drink. Because that rate cannot be sped up, the passage says only time, not black coffee or a cold shower, will sober you up. That directly supports choosing time as what eliminates alcohol from the bloodstream.
3. If feeling tired while driving, it is best to:
- Take a pep pill.
- Get some rest. ✓
- Continue driving.
Answer: B. Get some rest.
When you feel tired while driving, the best thing to do is get some rest. The handbook lists stopping driving to rest or nap as one of the ways to stay alert behind the wheel, and it warns that caffeine only helps for a few hours before wearing off, so you should not depend on it to prevent fatigue. Drugs may keep you awake but will not make you alert. The passage also points out that many drivers cannot tell when they are about to fall asleep, which is why the signs of fatigue should tell you to stop and rest.
4. Distracted driving:
- Is not a concern.
- Only occurs as a result of people who are physically doing something while driving.
- Can occur as a result of mental activities, such as daydreaming. ✓
- Is encouraged on uncrowded roads.
Answer: C. Can occur as a result of mental activities, such as daydreaming.
Distracted driving can occur as a result of mental activities, such as daydreaming. The handbook lists daydreaming and being occupied with other mental distractions among the activities inside a vehicle that can distract your attention. It also describes mental distraction as activities that take your mind away from the road, such as talking with a passenger or thinking about something that happened during the day. So distraction is not limited to physical actions. The same section warns that distracted driving can cause collisions and put you, your passengers, other vehicles, and pedestrians in danger.
5. Reading a text message while driving is:
- Encouraged.
- Allowed only if you are not pulling a trailer.
- Illegal. ✓
Answer: C. Illegal.
Reading a text message while driving is illegal. The handbook tells CMV drivers not to read or type text on a mobile device while driving, and it defines texting to include reading text from an electronic device. Federal rules cited in the handbook prohibit texting by CMV drivers operating in interstate commerce, and carriers may not require or allow it. So reading a message is not a permitted convenience; it falls under the banned behavior. The passages make no exception for whether a trailer is attached.
6. A liver can process about ____ per hour.
- One alcoholic drink ✓
- Two alcoholic drinks
- Three alcoholic drinks
Answer: A. One alcoholic drink
7. 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.
8. An alcohol evaporator is especially important:
- In cold weather. ✓
- In hot weather.
- In dry weather.
Answer: A. In cold weather.
An alcohol evaporator is especially important in cold weather. The handbook explains that certain air brake systems include an alcohol evaporator that adds alcohol to the air system. Its purpose is to lower the chance of ice forming in air brake valves and other parts when the weather is cold. The passage also says ice inside the system can make the brakes stop working. That supports the cold-weather choice, because the evaporator is described as protection against ice in air brake components.
9. 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.
10. A second conviction of operating a CMV with a minimum blood alcohol concentration (BAC) of 0.04 percent will result in:
- The loss of your CDL for life. ✓
- The loss of your CDL for five years.
- The loss of your CDL for one year.
Answer: A. The loss of your CDL for life.
