Questions (19)
1. Distracted driving:
- Is not a concern.
- Only happens when drivers are physically doing something, like using a cell phone.
- Can occur due to mental activities, such as daydreaming. ✓
- Is encouraged on uncrowded roads.
Answer: C. Can occur due to mental activities, such as daydreaming.
Distracted driving can occur because of mental activities, including 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 separates mental distraction, which takes your mind off the road, from physical distraction, which takes your hands or eyes away. That makes clear that distracted driving is not limited to handling a phone; thinking about something else while driving counts. The handbook says distracted driving can cause collisions and the resulting injury, death, or property damage.
2. 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.
3. 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
4. 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.
5. Texting while driving is worrisome:
- Because it creates both mental and physical distractions. ✓
- Because a message may be upsetting to the driver.
- Because the texts may be more interesting than the task of driving.
- Because it is less efficient than a phone call.
Answer: A. Because it creates both mental and physical distractions.
Texting while driving is worrisome because it creates both mental and physical distractions at the same time. The handbook says texting is the most alarming distraction because it involves physical and mental distraction simultaneously. It explains that you look at a small screen and work the keypad with your hands, while your mind is also pulled away from the road. That combination is why the handbook calls texting riskier than a phone call and ties it to a much greater chance of a safety-critical event. The answer that names both kinds of distraction matches that explanation.
6. 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.
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. Compared to talking on a cell phone while driving, texting while driving is:
- Much safer.
- Just as safe.
- More dangerous. ✓
Answer: C. More dangerous.
Texting while driving is more dangerous than talking on a cell phone. The handbook states that text messaging is even riskier than a phone conversation. It explains that texting pulls your eyes to a small screen and ties up your hands on the keypad, and it distracts you physically and mentally at the same time. That combination is why the handbook treats texting as the most alarming distraction. Talking on a phone can also distract you, but the passage puts texting in a higher-risk category, so the correct choice is the one saying it is more dangerous.
9. 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.
10. Which of the following is not a sign of fatigue?
- Difficulty focusing, with frequent blinking
- Yawning repeatedly or rubbing eyes
- Staying in your lane ✓
Answer: C. Staying in your lane
Staying in your lane is not a sign of fatigue — drifting out of your lane is. The handbook lists the warning signs of tired driving, and among them is drifting from your lane, along with trouble remembering the last few miles, missing exits or signs, following too closely, or hitting a shoulder rumble strip. It also mentions feeling restless and irritable. Holding a steady position in your lane is normal driving, not a fatigue signal. The handbook adds that pushing on while tired is more dangerous than most drivers think and is a major cause of fatal crashes, so any sign of fatigue means you should stop and sleep or take a short nap.
