Questions (20)
1. If your friend has been drinking alcohol, it is a good idea to do any of the following, except:
- Arrange for a safe ride home for your friend.
- Occupy your friend with activities to distract them from drinking.
- Keep your friend from leaving until they are sober.
- Allow your friend to ride their motorcycle. ✓
Answer: D. Allow your friend to ride their motorcycle.
The exception is allowing your friend to ride their motorcycle. The manual says that when a friend has been drinking, you should step in: involve them in other activities to slow the drinking, keep them there so they do not get on the motorcycle, arrange another way home, and wait until alcohol has left their system. Letting them ride goes against that guidance because alcohol affects judgment and riding skills. The other choices are protective steps the manual describes, so allowing the friend to ride is the one that does not belong.
2. Generally, the body eliminates one alcoholic drink per hour. If a person consumed eight alcoholic drinks four hours ago, how many drinks likely remain in their body?
- One drink
- Two drinks
- Three drinks
- Four drinks ✓
Answer: D. Four drinks
Four drinks likely remain in the body. The manual estimates alcohol elimination at about one drink per hour and shows the same subtraction in its examples: drinks consumed minus hours passed leaves the drinks still in the system. With eight drinks and four hours, about four drinks would have been eliminated, leaving about four. The manual adds that you would need more time before considering riding.
3. The only way to rid your body of alcohol is through:
- Time. ✓
- Drinking coffee.
- Exercising.
- Taking a cold shower.
Answer: A. Time.
The only way to rid your body of alcohol is time; the manual says alcohol clears at roughly one drink per hour. The handbook explains that alcohol enters the bloodstream quickly and affects mental and physical functions. It says the body eliminates alcohol at a rate of almost one drink per hour. It also says drinking faster causes more alcohol to build up and remain in your bloodstream. So the alcohol leaves as hours pass, not through another action you take.
4. Common drugs, such as cold tablets:
- Can affect a rider's abilities to safely operate their motorcycle. ✓
- Usually won’t affect a rider's abilities to safely operate their motorcycle.
- Pose no risk to a rider's operating abilities.
- Are always acceptable to take before riding because they are sold over-the-counter.
Answer: A. Can affect a rider's abilities to safely operate their motorcycle.
Common drugs such as cold tablets can affect a rider's ability to operate a motorcycle safely. The manual warns riders not to use drugs and says artificial stimulants can lead to extreme fatigue or depression when they wear off, leaving a rider unable to concentrate. It also says fatigue can affect control of the motorcycle. That supports treating common medications as something that can change your ability to ride safely. The manual does not name cold tablets specifically, so the support is the general warning about drugs and concentration.
5. How many alcoholic drinks need to be consumed before a rider may begin to feel the effects?
- One ✓
- Three to four
- Six
- More than eight
Answer: A. One
Even one alcoholic drink is enough for a rider to begin feeling the effects, so the answer is one drink. The manual explains that alcohol gets into the bloodstream fast, without needing digestion, and reaches the brain within minutes of being consumed. It slows and impairs both mental and physical functions, so you do less well at whatever you are doing. The manual also points out that abilities and judgment can be affected by that one drink, and that alcohol may keep building up in the body even when a person drinks at about one drink per hour, especially for women. That is why the count starts at a single drink.
6. Which of the following is not a factor in determining blood alcohol content (BAC)?
- The amount of alcohol consumed
- How fast the alcohol is consumed
- The drinker's body weight
- How often the drinker consumes alcohol ✓
Answer: D. How often the drinker consumes alcohol
How often the drinker consumes alcohol is not one of the factors that determine BAC. The manual names exactly three primary factors that decide blood alcohol concentration: how much alcohol you consume, how fast you drink, and your body weight. It also lists some secondary influences — your sex, physical condition, and food intake — but drinking frequency is not among them. That is why the correct pick is the one about how often someone drinks. Notice the manual is not saying experience with alcohol makes you safe; it simply does not count drinking frequency as a BAC factor.
7. The effects of marijuana consumption can last for:
- No more than 15 minutes.
- About an hour.
- About two hours.
- More than six hours. ✓
Answer: D. More than six hours.
Marijuana's effects can last more than six hours when it is eaten, so that is the longest duration listed among the choices. The manual explains that how cannabis gets into your body changes the timeline. Smoked cannabis starts acting within a few minutes and generally lasts from 2 to 4 hours. Eaten cannabis is different: the onset can be delayed more than an hour, and the high itself can run past 6 hours. Since the choices ask about the effects lasting, the only duration the manual describes that goes beyond a few hours is the eaten form, which is listed as more than 6 hours. The manual also warns that cannabis distorts your sense of time, space and speed, which matters a lot on a motorcycle.
8. If you wait one hour to ride after having one alcoholic drink:
- You cannot be arrested for drinking and driving.
- Your riding skills will not be affected by the alcohol.
- Effects from the alcohol may still remain. ✓
- You will be fine as long as you ride slowly.
Answer: C. Effects from the alcohol may still remain.
Even after waiting an hour for one drink, the effects of the alcohol may still remain. The manual states that alcohol may still build up in your body even when you drink at a rate of one drink per hour, especially for women, and that a single drink can affect your abilities and judgment. It also notes that a person who has been drinking may not realize how much their skills have suffered. So waiting an hour does not guarantee that the alcohol is gone or that you are unaffected.
9. Generally, the body eliminates how many alcoholic drinks per hour?
- One ✓
- Two
- Three
- Four
Answer: A. One
Generally, the body eliminates about one alcoholic drink per hour. The manual says alcohol leaves the body at a rate of almost one drink per hour. That is why the answer is one. The same section warns that this is only a general rate: how much you drink, how fast you drink, and body weight affect BAC, and alcohol can still build up even when you drink at about one per hour, especially for women. So one drink per hour is the usual elimination figure, not a guarantee that you are unaffected.
10. In regards to drinking and riding, many penalties are:
- Severe. ✓
- Up to a judge to decide.
- Not too harsh.
- Optional.
Answer: A. Severe.
Many penalties for drinking and riding are severe, and most states now impose them as mandatory penalties. The manual explains that first offenders once expected a small fine and alcohol classes, but the laws of most states now impose stiff penalties on drinking operators. It also says those penalties are mandatory, so judges must impose them rather than choosing whether to. The listed consequences include mandatory license suspension, severe fines, higher insurance rates, and community service. That support makes the point that the penalties are severe, not light or optional.
