Questions (12)
1. 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.
2. If operating a school bus, you are considered to be driving under the influence of alcohol if you have a minimum blood alcohol content (BAC) of:
- 0.02 percent. ✓
- 0.04 percent.
- 0.08 percent.
- 0.1 percent.
Answer: A. 0.02 percent.
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. How could you reduce your stress while driving?
- Drink a caffeinated beverage
- Talk on your cell phone
- Gesture at other drivers
- Listen to calming music ✓
Answer: D. Listen to calming music
Listening to calming music, such as easy listening, is a way to reduce your stress while driving. The handbook's section on not being an aggressive driver tells you to reduce stress before and while you drive, and one of its listed steps is to listen to easy listening music. The same passage pairs this with giving the drive your full attention and not letting cell phone talk or eating distract you. So calming music is the stress-reducer the handbook names, while the other choices either add distraction or make things worse.
5. A driver will lose their CDL for a minimum of ____ for a first-time conviction of driving a CMV with a blood alcohol content (BAC) of 0.04 percent.
- One month
- Three months
- Six months
- One year ✓
Answer: D. One year
6. To best reduce the distractions of a cell phone, you should:
- Stay on a single call for an entire trip.
- Turn the phone off before driving. ✓
- Only us the phone to accept incoming calls.
- Use the phone to text rather than talk.
Answer: B. Turn the phone off before driving.
7. Which of the following is not a sign of fatigue?
- Ability to focus ✓
- Daydreaming
- Yawning repeatedly
- Drifting from your lane
Answer: A. Ability to focus
The one that is not a sign of fatigue is the ability to focus. The handbook's fatigue section lists drifting from your lane and trouble recalling recent miles as warning signs, and it says pushing on while tired is a major cause of fatal crashes. Being able to focus is the opposite of the reduced attention those signs point to. The handbook does not list focus as a fatigue warning; it tells you to stop when warning signs appear.
8. Over-the-counter medication:
- Poses no safety risks to a driver.
- Is not referenced by any laws regarding driving under the influence.
- Cannot impair a driver.
- Can affect a person’s ability to drive safely. ✓
Answer: D. Can affect a person’s ability to drive safely.
Over-the-counter medication can affect a person’s ability to drive safely. The handbook lists prescription and over-the-counter drugs, such as cold medicines, among substances that can make a driver unsafe. It says these medicines may make you drowsy or otherwise affect your ability to drive safely. It also tells drivers to pay attention to warning labels and doctor's orders about possible effects. That is why the bank answer treats OTC medication as something that can change how safely you drive, not as a harmless product.
9. 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.
10. 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.
