Correct answer: Smoking acts within minutes and lasts 2 to 4 hours, while eating can be delayed over an hour and last more than 6
Smoking brings effects on within a few minutes that run 2 to 4 hours; eating it can push the onset out past an hour and stretch the effects beyond 6 hours.

2. How fast does the body generally get rid of alcohol?
Correct answer: About one drink an hour
The body clears roughly one drink's worth of alcohol each hour, so drinking faster than that leaves alcohol building up in the bloodstream.

5. How does marijuana affect a rider, according to the manual?
Correct answer: It distorts the sense of time, space, and speed
It warps a rider's sense of time, space, and speed, which is critical on a motorcycle because riders must size up complex traffic scenes and act on split-second decisions.

6. What blood alcohol level puts a Hawaii driver under 21 in violation of the law?
Correct answer: .02 or more
Under the state's zero tolerance rule, anyone under 21 is barred from operating a vehicle at a blood alcohol content of .02 or higher.

7. A rider has seven drinks over three hours. Roughly how much alcohol is still in the system at the end?
Correct answer: The equivalent of about four drinks
Because the body clears about one drink an hour, seven drinks in three hours leaves the equivalent of about four still on board, and clearing those takes about four more hours.

8. In Hawaii, what blood alcohol range makes a driver legally impaired rather than under the influence?
Correct answer: More than .05 percent but under .08 percent
A result above .05 percent but below .08 percent counts as impaired; .08 percent or higher counts as under the influence of alcohol.

9. Why does the manual highlight the extra 8 percent of fatally injured riders whose blood alcohol ran between 0.01 and 0.07 percent?
Correct answer: It shows that even one or two drinks can impair a rider
Those riders were under the legal limit and still died, which shows that a drink or two is enough to damage riding skill.

10. Which three things chiefly determine a rider's blood alcohol concentration?
Correct answer: How much you drink, how fast you drink it, and your body weight

11. How does a can of beer compare with a glass of wine or a mixed drink?
Correct answer: All three carry the same amount of alcohol
A 12-ounce beer, a 5-ounce glass of wine, and a mixed drink built on a single 1.5-ounce shot all deliver the same quantity of alcohol.

12. What does alcohol impair first in a rider?
Correct answer: Judging how well you are riding
Your judgment of your own riding goes first, so performance drops while the rider believes it is improving and starts taking bigger risks.
