Questions (26)
1. Studies show that nearly ______ of riders killed in motorcycle crashes had been drinking.
- 20 percent
- 40 percent ✓
- 60 percent
- 80 percent
Answer: B. 40 percent
Studies show that nearly 40 percent of riders killed in motorcycle crashes had been drinking. The manual reports that alcohol plays a large part in fatal motorcycle crashes. It says nearly a third of fatally injured riders had blood alcohol levels over the legal limit, and another 8 percent had lower levels. Adding those two groups gives a figure close to 40 percent, which is what the question is asking for. The manual draws the point that even a drink or two is enough to impair riding, so impairment and riding do not belong together.
2. 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.
3. If you wait an hour per alcoholic drink before you ride your motorcycle:
- You cannot be arrested for drinking and riding.
- Your skills will not be affected.
- Side effects may still remain. ✓
- You will be fine as long as you ride slowly.
Answer: C. Side effects may still remain.
Even if you wait an hour per alcoholic drink, side effects may still remain. Waiting one hour for each drink is not a guarantee that alcohol is gone. The manual's own answer says that drinking may leave side effects that continue. Another page explains that alcohol can still build up even when you have about one drink per hour, and that one drink can affect abilities and judgment. So the fact that an hour has passed for each drink does not mean you are clear to ride.
4. Unlike most food and drinks, alcohol does not need to be digested. This means that:
- Within minutes of being consumed, the alcohol reaches the brain and begins to affect the drinker. ✓
- The alcohol never gets removed from the body.
- It takes a long time to feel the effects of alcohol.
- Once it is in your system, your body gets rid of the alcohol quickly.
Answer: A. Within minutes of being consumed, the alcohol reaches the brain and begins to affect the drinker.
Because alcohol needs no digestion, it reaches the brain and starts affecting you within minutes of being consumed. The manual says alcohol enters the bloodstream quickly and, unlike most foods and beverages, does not have to be digested. Within minutes of being consumed, it reaches the brain and begins to affect the drinker. That is why the answer about it hitting the brain within minutes is the right one. The same passage adds that alcohol slows down and impairs both mental and physical functions, so whatever you are doing, you do it less well after drinking.
5. You have been drinking alcohol. If you wait an hour for each drink before riding your motorcycle:
- You cannot be arrested for drinking and riding.
- Your riding skills will not be affected.
- Side effects from the drinking may still remain. ✓
- You will be okay as long as you ride slowly.
Answer: C. Side effects from the drinking may still remain.
Even if you wait an hour for each drink, side effects from the drinking may still remain. The manual's own review question matches this exactly: waiting one hour per drink does not mean all effects are gone, and side effects may still remain. It explains that alcohol can accumulate even when you drink at a rate of one drink per hour, especially for women, and that abilities and judgment can be affected by that one drink. Its examples show drinks can remain in your system after the time you spent drinking, so more time may be needed before riding.
6. If only one alcoholic drink is consumed:
- Judgment and riding abilities can still be affected. ✓
- There is usually no effect on the body.
- There is an effect on the body, but it only lasts for a short time.
- There is an effect on the body, but it can be eliminated by drinking coffee.
Answer: A. Judgment and riding abilities can still be affected.
Even one alcoholic drink can affect your judgment and riding abilities. The manual explains that alcohol builds up in your blood, and the level in your blood decides how impaired you are. It notes that alcohol may still collect in your body even when you drink only one drink per hour, and it says plainly that abilities and judgment can be affected by that one drink. Because good judgment is one of the first things alcohol touches, you cannot assume a single drink leaves your riding unaffected.
7. In general, the body gets rid of almost ______ per hour.
- One drink ✓
- Two drinks
- Three drinks
- Four drinks
Answer: A. One drink
In general, the body eliminates alcohol at a rate of almost one drink per hour. The manual states that alcohol is generally eliminated at a rate of almost one drink per hour. That is the baseline rate it gives for how fast the body clears alcohol. A separate passage adds that if you drink two drinks in an hour, at least one drink will remain in your bloodstream at the end of that hour, which shows that faster drinking outpaces elimination. So the amount matching the manual's general rate is one drink, not a larger number.
8. When consumed together, the effects of alcohol and drugs:
- Can be more pronounced than when either is consumed alone. ✓
- Are less dangerous than when either is consumed alone.
- Are usually minimal.
- Often balance out.
Answer: A. Can be more pronounced than when either is consumed alone.
When alcohol and drugs are consumed together, their effects can be more pronounced than when either is consumed alone. The manual states plainly that alcohol and drugs together are more dangerous than either one by itself. It explains that alcohol and drugs impair judgment, clear thinking, and the physical skills needed to ride, and that impairment can begin before legal limits are reached. Since each substance already reduces your ability to ride well, the manual's warning about combined effects supports the answer that the effects can be stronger together than alone.
9. To prevent getting fatigued on a long ride, you should do all of the following, except:
- Dress warmly.
- Limit the distance traveled in a day.
- Take frequent rest breaks.
- Take artificial stimulants. ✓
Answer: D. Take artificial stimulants.
To prevent fatigue on a long ride, do not take artificial stimulants; the other listed habits are recommended fatigue fighters. The motorcycle manual says riding is more tiring than driving, so you should protect yourself from wind, cold, and rain by dressing warmly, limit how far you ride in a day, and stop for frequent rest breaks. It separately warns against drinking or using drugs. Artificial stimulants are specifically described as often causing extreme fatigue or depression when they wear off, leaving a rider unable to concentrate. That makes taking stimulants the exception among the choices, not a fatigue-prevention method.
10. 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.
