Questions (19)
1. Texting while operating a CMV is:
- Illegal. ✓
- Acceptable on rural roads.
- Acceptable for drivers contacting their employers.
Answer: A. Illegal.
Texting while operating a CMV is illegal. The handbook's texting section says federal rules prohibit CMV drivers from texting while driving in interstate commerce, and it adds that motor carriers may not require or allow drivers to text. Another passage ties texting violations to CDL disqualification and civil penalties, with only an emergency exception for contacting law enforcement or emergency services. So texting is not permitted based on road type or because an employer wants contact. The answer is the choice saying it is illegal.
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. If approaching a vehicle with a distracted driver, you should:
- Quickly pass the vehicle.
- Maintain a safe distance from the vehicle. ✓
- Closely follow the vehicle.
Answer: B. Maintain a safe distance from the vehicle.
When you approach a vehicle whose driver seems distracted, keep a safe distance back from it. The handbook tells you to give a distracted driver plenty of room and hold your normal safe following distance. It also warns that these drivers drift over lane lines or within their lane and run at inconsistent speeds, so staying back gives you room to see and react. The handbook adds that passing such a driver calls for extra care, because they may not notice you and may drift in front of you. Space is the protection it recommends, so holding a safe distance is the right choice.
4. If you identify a distracted driver on the road, you should:
- Tailgate them.
- Flash your lights at them.
- Give them plenty of space. ✓
Answer: C. Give them plenty of space.
When you spot a distracted driver, give them plenty of space and keep your safe following distance. The handbook says you first need to recognize drivers who are distracted, then give them plenty of room while holding your normal safe following distance. It adds that you should be very careful when passing such a driver, because they may not notice you and may drift in front of you. That guidance points to putting distance between your vehicle and theirs, not staying close or trying to signal them.
5. 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.
6. Which of the following determines your blood alcohol concentration (BAC)?
- How much you drink ✓
- How frequently you drink
- The temperature of the drink
Answer: A. How much you drink
The amount you drink determines your blood alcohol concentration (BAC). Your blood alcohol concentration goes up with the amount of alcohol you drink. The handbook lists the amount consumed, how fast you drink, and your weight as the things that set BAC, with more alcohol producing a higher BAC. It also says the source of the alcohol does not matter, so whether it comes from beer, wine, or liquor, what counts is the alcohol itself. Nothing in the passages says the temperature of a drink changes BAC. That is why the amount you drink is the listed factor among these choices.
7. 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.
8. You may be able to identify a distracted driver by if they are:
- Staying within their lane.
- Traveling at consistent speeds.
- Preoccupied with using their cell phone. ✓
Answer: C. Preoccupied with using their cell phone.
You can spot a distracted driver when they are preoccupied with using a cell phone. The handbook's list of signs to watch for includes drivers who are busy with maps, food, cigarettes, cell phones, or other objects. It also tells you to look for vehicles drifting over lane lines or within their lane and vehicles moving at inconsistent speeds. A driver focused on a phone fits the handbook's description of someone engaged in a driving distraction. Recognizing that behavior helps you give the distracted driver room and be careful when passing, because they may not notice you and may drift in front of you.
9. Alcohol evaporators are:
- Illegal.
- Used to introduce alcohol into air brake systems. ✓
- Only allowed in the northern parts of the state.
Answer: B. Used to introduce alcohol into air brake systems.
10. The more alcohol in the body:
- The quicker the liver will digest the alcohol.
- The less effect the alcohol will have on the individual.
- The longer it will take to remove the alcohol from the body. ✓
Answer: C. The longer it will take to remove the alcohol from the body.
The more alcohol in the body, the longer it will take to remove it, so choose the answer saying removal takes longer. The handbook explains that the liver handles alcohol at a fixed rate — only about one-third of an ounce per hour, which is less than what a standard drink contains. Because that rate does not speed up, drinking faster than the body can clear alcohol means more of it builds up in your blood. The handbook states plainly that only time, not black coffee or a cold shower, sobers you up. So a larger amount of alcohol in the body simply means a longer wait before it is gone.
