5. How do a can of beer, a glass of wine and a shot of liquor compare?

6. How fast does the body clear alcohol?

10. Which ability does alcohol undermine first?
Correct answer: Your judgment, including your sense of how well you are riding

11. Which three factors mainly decide a rider's blood alcohol concentration?
Correct answer: How much you drink, how quickly you drink it and how much you weigh

12. What does the manual recommend about fatigue on a long ride?
Correct answer: Get off the motorcycle for a break at least every two hours
Riding tires you faster than driving, so experienced riders rarely stay out more than about six hours a day, dress against wind and cold, and stop regularly.
