Motorcycle Alcohol & Drugs Practice Questions
Alcohol & Drugs makes up 5 of every 50 questions on a Tigertest Motorcycle practice test. Here are 10 of the 20 questions on it, each with the answer and the reason.
Updated by the Tigertest team. Based on the MSF Motorcycle Operator Manual used by nearly every state. Check your state's handbook for local rules.
1. Compared with its role in other traffic, how does alcohol figure in fatal motorcycle crashes?
- A.It matters only for riders under 21
- B.Riders who had been drinking are overrepresented
- C.It affects car crashes but rarely motorcycle crashes
- D.It plays a role in very few crashes
Answer: B. Alcohol is a major contributor to motorcycle crashes, especially fatal ones. A large share of riders killed in crashes had been drinking.
2. At a gathering, a riding buddy keeps drinking and plans to leave soon. Which approach helps keep the buddy off the motorcycle?
- A.Let the buddy leave before drinking more
- B.Offer energy drinks so the buddy stays alert enough
- C.Stay out of it; it is the buddy's choice
- D.Slow the drinking and get other friends involved
Answer: D. Slowing the pace of drinking, keeping the person there, and enlisting friends make it easier to stop an impaired rider. Caffeine does not reduce impairment.
3. When a rider drinks alcohol, which ability is usually affected first?
- A.Judgment
- B.Hearing
- C.Muscle strength
- D.Sense of smell
Answer: A. Alcohol impairs judgment first, often before a rider notices any loss of coordination, so the decision to ride is made with impaired judgment.
4. A rider has had two beers and says, 'I feel fine to ride.' Why is this feeling unreliable?
- A.Feeling fine means the blood alcohol level must be zero
- B.Two beers are cleared within minutes
- C.Judgment is impaired before skills seem affected
- D.Beer has no effect on riding skills
Answer: C. Because judgment fails first, impaired riders often feel capable while their reaction time and coordination are already reduced.
5. Which of these contains about the same amount of alcohol as a 12-ounce can of beer?
- A.A 12-ounce glass of wine
- B.A 6-ounce glass of liquor
- C.A 5-ounce glass of wine
- D.Two 5-ounce glasses of wine
Answer: C. A 12-ounce beer, a 5-ounce glass of wine, and a 1.5-ounce shot of liquor each contain about the same amount of alcohol.
6. A standard drink of 80-proof liquor, equal in alcohol to one 12-ounce beer, is about how much?
- A.1.5 ounces
- B.5 ounces
- C.12 ounces
- D.0.5 ounce
Answer: A. One drink of liquor is about a 1.5-ounce shot, which holds about as much alcohol as a 12-ounce beer or 5-ounce glass of wine.
7. On average, about how fast does the body eliminate alcohol from the blood?
- A.About one drink every ten minutes
- B.About one drink per day
- C.About three drinks per hour
- D.About one drink per hour
Answer: D. The body eliminates roughly one drink per hour. Drinking faster than that makes the blood alcohol concentration climb.
8. A rider finished three beers at a party and wants to sober up quickly before riding. What actually lowers BAC?
- A.Drinking strong black coffee
- B.Only time
- C.Taking a cold shower
- D.Exercising or walking around
Answer: B. Only time removes alcohol from the body. Coffee, cold showers, and exercise may make a person feel more awake but do not lower BAC.
9. Which factors chiefly determine a person's blood alcohol concentration (BAC)?
- A.The rider's years of motorcycle riding experience
- B.How much is drunk, how fast, and body weight
- C.The type of drink and its color
- D.Time of day and air temperature
Answer: B. BAC depends mainly on how much alcohol you drink, how quickly you drink it, and your body weight. Beer, wine, and liquor all count equally per standard drink.
10. In most states, what is the legal blood alcohol limit for riders 21 and older?
- A.0.15 percent
- B.0.80 percent
- C.0.20 percent
- D.0.08 percent
Answer: D. Most states set the adult limit at 0.08 percent BAC, but a rider can be impaired, and arrested, below that level.
