Questions (19)
1. One way to prevent fatigue on long trips is to:
- Take frequent breaks. ✓
- Text while driving.
- Drink caffeine.
Answer: A. Take frequent breaks.
Taking frequent breaks is the recommended way to prevent fatigue on long trips. The handbook lists reducing fatigue risk by taking periodic breaks, roughly every 100 miles or every 2 hours on a long trip. It also tells you to stop driving and rest or nap when you notice signs of tiredness. Caffeine gets its own warning: it may boost awareness for a few hours, but the effect wears off, so the handbook says not to count on it to prevent fatigue. Rest breaks are the method the handbook actually endorses.
2. Alcohol is removed from the body:
- By exercising.
- At a fixed rate. ✓
- More quickly if the person stays awake.
Answer: B. At a fixed rate.
Alcohol is removed from the body at a fixed rate. The handbook says the liver can process only one-third of an ounce of alcohol per hour, and it calls this a fixed rate. Because the body clears alcohol at that steady pace, drinking faster than the body can remove it leaves more alcohol in your system and affects driving more. The passage also says only time sobers you up, not black coffee or a cold shower. So the removal speed does not change with activity or staying awake.
3. Of the following, which is not a way to prevent drowsiness during a trip?
- Getting an adequate amount of sleep before driving
- Traveling with a passenger
- Scheduling trips during hours when you would not normally be awake ✓
- Avoiding medications that may cause drowsiness
Answer: C. Scheduling trips during hours when you would not normally be awake
Scheduling trips during hours when you would not normally be awake is not a way to prevent drowsiness — it actually raises your risk. The handbook lists driving at night, mid-afternoon, or when you would normally be asleep as a cause of drowsy driving, and notes many heavy motor vehicle accidents happen between midnight and 6 a.m. Its advice for preventing drowsiness before a trip is the opposite: plan your driving for the hours you are normally awake, not the middle of the night. Choosing to drive when your body expects sleep works against you rather than protecting you.
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. For a first conviction of driving with a blood alcohol concentration (BAC) of 0.04 percent or higher, you will lose your CDL for:
- One month.
- Three months.
- One year. ✓
Answer: C. One year.
6. Alcohol evaporators are:
- Illegal.
- Used to add alcohol to braking systems to prevent items from freezing. ✓
- Only allowed on vehicles carrying hazardous materials.
Answer: B. Used to add alcohol to braking systems to prevent items from freezing.
Alcohol evaporators are used to put alcohol into the air brake system so ice is less likely to form in the valves and other parts in cold weather. The handbook explains that some air brake systems carry an alcohol evaporator that feeds alcohol into the air system. That alcohol lowers the chance of ice building up in air brake valves and other components when the weather is cold. The handbook also points out why this matters: ice inside the system can stop the brakes from working. So the device is a cold-weather safeguard for the air brake system, not a fuel additive or an extra for certain loads.
7. 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.
8. 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.
9. 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.
10. 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.
