1. At what blood alcohol level is a driver under 21 breaking Hawaii's zero tolerance rule?
Correct answer: 0.02 or more
Drivers below the age of 21 must not operate a vehicle with a blood alcohol content of 0.02 or higher - a far lower bar than the 0.08 that applies generally.
2. A test shows a driver at 0.08 blood alcohol. What happens to the license?
Correct answer: It is taken away and a 30-day temporary permit is issued
At 0.08 or above - and also on a refusal - the license is taken away and a temporary permit lasting 30 days is issued in its place. A hearing may be requested.
3. What does the manual say about mixing alcohol with other drugs?
Correct answer: The combination can hit far harder than either one alone
Taken together the two can produce an effect far stronger than either would on its own, which is why the manual says never to combine them.
4. What does Hawaii's implied consent rule mean for anyone driving on public highways?
Correct answer: You have already agreed to be tested for alcohol in your blood
By driving on the public highways you are treated as having already agreed to be tested for the amount of alcohol in your blood.
5. How long can a license be revoked for refusing an alcohol test in Hawaii?
Correct answer: One, two or four years, depending on prior alcohol enforcement contacts
A refusal can cost a driver one year, two years or four years, and which of those applies turns on the driver's earlier alcohol enforcement contacts.
6. Which of these will actually reduce the alcohol already in your bloodstream?
Correct answer: Only the passing of time
Nothing you can drink or do speeds the process up. The liver burns the alcohol off and the kidneys and lungs clear it, and that takes as long as it takes.
7. Which everyday medicines does the manual warn can affect your driving?
Correct answer: Allergy remedies and cold tablets bought over the counter
Some allergy remedies and cold tablets sold without a prescription contain ingredients that interfere with driving, which is why you should ask your doctor before taking medicine.
8. Why can the same drink hit you harder on one occasion than another?
Correct answer: An empty stomach speeds up how fast it reaches you
Alcohol taken on an empty stomach reaches you more quickly than the same amount taken after a meal, which is one reason its effects vary from day to day.
9. Why do some people feel livelier after a few drinks?
Correct answer: Their inhibitions have dropped, costing them caution and self-control
The lift is an illusion created by lowered inhibitions. What has really gone is caution and self-control, not tiredness.
10. Why does the manual call every drug from the illegal market dangerous?
Correct answer: Their strength and purity cannot be known
There is no way to know how strong or how pure such a substance is, so the person taking it cannot judge what it will do to them.
11. A test puts a driver above 0.05 but below 0.08. How does Hawaii describe that driver?
Correct answer: Impaired
That band is labelled impaired. Reaching 0.08 or above moves the driver into the separate category of being under the influence of alcohol.
12. Does it matter whether you drink beer, wine or spirits?
Correct answer: No, what counts is the amount of alcohol reaching your blood
The kind of drink is beside the point. What causes the problem is how much alcohol ends up in the bloodstream.
