1. Why does alcohol affect a rider so quickly?
Correct answer: It doesn't need to be digested and reaches the brain within minutes
Unlike most food and drink, alcohol goes straight into the bloodstream, and its main effect is to slow down and impair both mental and physical functions.

4. If a rider has seven drinks over three hours, at minimum how many drinks' worth of alcohol would still be in their system when those three hours end?
Correct answer: At least four
With the body clearing roughly one drink per hour, seven drinks minus three hours leaves at least four, which would take at least four more hours to eliminate before considering riding.

5. Why is riding while impaired by marijuana especially dangerous for motorcyclists?
Correct answer: It tends to distort your sense of time, space and speed
Riders must constantly assess complex traffic and make split-second decisions, so distorted perception is especially risky. A rider impaired by marijuana faces the same kind of under-the-influence charge and harsh penalties as with alcohol.

6. According to New Hampshire's driver manual, what is the one thing that actually lowers alcohol's effects?
Correct answer: Time
Coffee, food, fresh air, exercise or a cold shower may make someone feel more alert, but none of them counter alcohol. Each ounce takes about an hour to leave the body.

7. Which is a strategy the motorcycle manual suggests to keep a friend who has been drinking from riding?
Correct answer: Take their key, if possible, and lock up their motorcycle
Other suggestions include arranging a safe ride, slowing the pace of drinking, keeping them there with food and coffee, and enlisting other friends to help.

8. Why does the motorcycle manual describe today's drinking-and-riding penalties as mandatory?
Correct answer: Judges must impose them
Most states now impose stiff penalties that judges are required to hand down, unlike the small fines first offenders once faced.

10. Which three factors does the motorcycle manual say play the major part in determining BAC?
Correct answer: How much alcohol you drink, how fast you drink it, and your body weight
Amount, pace and body weight are the primary factors. Sex, physical condition and food intake can also push BAC higher.

11. After drinking, what usually settles whether your riding is legal?
Correct answer: A breath, blood or urine test
How sober you seem doesn't matter; a chemical test is what usually decides. Your judgment and skills start to suffer at levels far under the legal limit.

12. When marijuana is eaten rather than smoked, what does the motorcycle manual say about its effects?
Correct answer: Onset can be delayed more than an hour, and the high can last over 6 hours
Smoked marijuana usually takes effect within minutes and lasts 2 to 4 hours; eaten, it can take much longer to start and last much longer.
