Questions (22)
1. After drinking, what lessens the effects of alcohol?
- Exercise
- Coffee
- Time ✓
- Food
Answer: C. Time
Time is what lessens the effects of alcohol; your body has to eliminate it. The manual says alcohol is eliminated from the body at a rate of almost one drink per hour, and it tells riders who have exceeded their limit to wait until their system clears the alcohol and its after-effects. That makes time, not a quick fix, the listed way for the effects to wear off. The manual also notes that even after waiting an hour per drink, side effects may still remain, so the point is to allow the body time rather than try to speed things up.
2. 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.
3. How do headache, cold, and hay fever medications usually affect your body?
- They make you drowsy. ✓
- They make you more alert.
- They make you hungry.
- They make you unable to concentrate.
Answer: A. They make you drowsy.
4. If a friend has been drinking and wants to ride their motorcycle, you should:
- Let them.
- Encourage them to take less-crowded roads.
- Push their bike over.
- Encourage friends to talk them out of riding. ✓
Answer: D. Encourage friends to talk them out of riding.
Encourage friends to talk them out of riding — the manual says to get a group of friends involved and use peer pressure to intervene. The manual treats a rider who has had too much to drink as someone who cannot make a responsible decision, so it falls to others to step in and stop them from taking a big risk. One of its listed tactics is to get friends involved: bring a group together and use peer pressure to intervene. It also suggests slowing the drinking, keeping the person there with excuses, taking the key and securing the bike, or arranging another way home.
5. 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.
6. Fatigue can be increased by:
- Stopping frequently.
- Riding in cool weather. ✓
- Being comfortable during your ride.
- Starting a ride late in the day.
Answer: B. Riding in cool weather.
Cold conditions raise fatigue, so riding in cool weather is the choice that increases it. The manual lists wind, cold, and rain as things that make you tire quickly, and it warns that riding for long periods in cold weather can bring on severe chill and fatigue. Numb, cold hands and a chilled body make it harder to control the motorcycle. That is why the manual tells you to dress warmly and, on long rides, to use a windshield. Starting a ride fresh and staying comfortable works against fatigue, and stopping to rest is the manual's own remedy, so neither of those increases it.
7. Impairment from drinking alcohol occurs:
- Well below the legal limit. ✓
- Once reaching the legal limit.
- Just above the legal limit.
- Well above the legal limit.
Answer: A. Well below the legal limit.
Impairment from drinking alcohol begins well below the legal limit. The manual says the real question is not whether you are legally intoxicated, because your judgment and riding skills start to slip well below the legal limit. The stats passage backs this up: riders with BAC from 0.01 to 0.07 percent, meaning just a drink or two, already showed that a small amount is enough to impair riding skills. So the trouble starts earlier than the legal cutoff, not at it.
8. A person with a minimum blood alcohol concentration (BAC) of ______ is considered legally intoxicated.
- 0.02 percent
- 0.04 percent
- 0.08 percent ✓
- 0.1 percent
Answer: C. 0.08 percent
A person is considered legally intoxicated at a blood alcohol concentration of 0.08 percent. The manual states that in all but one state, an adult with a BAC of 0.08% or above is treated as intoxicated; Utah is the single exception with a 0.05% threshold. The same page repeats that 0.08% is the legal limit when it describes riders killed in crashes with BAC levels above it. So for adults generally, 0.08 percent is the number the law uses, and that is the figure the test is asking for.
9. Several factors influence blood alcohol concentration (BAC). Which of the following does not play a role?
- The amount of alcohol consumed
- How fast a person drinks
- Body weight
- Height ✓
Answer: D. Height
Height is the factor that does not play a role in blood alcohol concentration; the manual names how much alcohol you drink, how fast you drink it, and your body weight as the main influences. The manual lists three primary factors that determine BAC: the amount of alcohol you consume, how fast you drink, and your body weight. It adds that other things, such as sex, physical condition and food intake, can also change how alcohol affects you. Height is not on that list of primary factors or among the additional ones the manual mentions, so it is the one item here that does not affect BAC.
10. 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.
