Questions (14)
1. Alcohol is removed from the body:
- At a rate that changes depending on how much alcohol is in the body.
- At a consistent rate, regardless of how much alcohol is in the body. ✓
- More quickly if the person drinks coffee.
- More quickly if the person stays awake.
Answer: B. At a consistent rate, regardless of how much alcohol is in the body.
Alcohol is removed at a consistent rate, regardless of how much alcohol is in the body. The handbook says the liver can process only a small, set amount of alcohol per hour, and it calls that a fixed rate. Because the rate stays the same, having more alcohol in the body does not make removal speed up. It also says only time will sober you up, so coffee or a cold shower does not change the rate. Drinking faster than the body clears alcohol just lets more build up.
2. To prevent fatigue while driving, you should:
- Keep the cab warm.
- Keep the cab cool. ✓
- Keep the cab poorly ventilated.
- Close the vents.
Answer: B. Keep the cab cool.
Keep the cab cool — the handbook's alertness list says to keep cool by opening a window or running the air conditioner. The fatigue section of the handbook gives a short list of things you can do to stay alert behind the wheel, and one of those items is to keep cool by opening the window or using the air conditioner. That cooling advice sits right alongside other alertness habits such as wearing sunglasses against glare and eyestrain, taking periodic breaks, and stopping to rest or nap. Since the handbook names keeping cool as the way to help maintain alertness, keeping the cab cool is the choice that matches it.
3. How can you avoid becoming drowsy on a trip?
- Get about three hours of sleep beforehand.
- Plan ahead, including stopping points. ✓
- Do not build exercise into your daily routine.
- Schedule the trip at night.
Answer: B. Plan ahead, including stopping points.
4. What is the only way to sober up after drinking?
- Take a cold shower.
- Exercise.
- Wait. ✓
- Drink coffee.
Answer: C. Wait.
The only way to sober up is to wait — only time removes alcohol from your body. The handbook explains that alcohol moves into your bloodstream and is carried to the liver, and the liver works at a fixed rate, handling just one-third of an ounce per hour, which is less than the alcohol in a standard drink. Because that rate does not change, the handbook says plainly that only time, not black coffee or a cold shower, will sober you up. So the sobering happens on the body's schedule, and your job is simply to let the hours pass before you drive.
5. If a driver begins to feel fatigued while driving, they should:
- Continue driving.
- Drink coffee.
- Stop and rest. ✓
- Drive faster to finish the trip more quickly.
Answer: C. Stop and rest.
If you begin to feel fatigued while driving, you should stop and rest. The handbook's fatigue section says that when you feel tired, you should stop driving and get some rest or take a nap. It also says caffeine can increase awareness for only a few hours, then wears off, so you should not rely on it to prevent fatigue. The signs of fatigue should tell you to stop and rest. That supports stopping to rest rather than continuing, using coffee, or trying to finish faster.
6. 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.
7. Which of the following is not a sign of a person being drowsy?
- Frequent blinking
- Drifting from your lane
- Feeling hungry ✓
- Yawning
Answer: C. Feeling hungry
Feeling hungry is not a sign of drowsiness; the handbook's fatigue warnings include drifting from your lane and feeling restless or irritable. Feeling hungry is not among the fatigue warning signs the Texas CDL Handbook gives. The handbook tells drivers to stop and rest when they notice signs such as drifting from the lane, following too closely, hitting a shoulder rumble strip, trouble remembering the last few miles, missing exits or signs, or feeling restless and irritable. It describes fatigue as physical or mental tiredness that impairs vision and judgment. Hunger is not listed as an alertness warning, while lane drifting is directly named.
8. About how many drinks does it take for a 200-pound person to reach a 0.02 percent blood alcohol concentration (BAC)?
- One ✓
- Two
- Three
- Four
Answer: A. One
9. When you are driving while drowsy, you should:
- Press on and try to finish the trip.
- Take drugs to keep awake.
- Stop and take a nap. ✓
- Stop for a coffee break.
Answer: C. Stop and take a nap.
When you are driving while drowsy, you should stop and take a nap. The handbook lists stopping driving and getting rest or taking a nap as a way to stay alert. It also says that when you notice signs of fatigue, you should stop driving and either sleep for the night or take a 15–20 minute nap. It warns that trying to push on when tired is far more dangerous than many drivers think and is a major cause of fatal accidents.
10. 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.
