1. What does Delaware's implied consent law mean for a driver arrested on suspicion of impaired driving?
Correct answer: By driving, they have already agreed to a chemical test of breath, blood or urine
Anyone arrested for driving while impaired, whether in a car, on an off-highway machine or on a moped, is deemed to have consented. Refusing brings a report to the Division and can cost the license for one to two years.

4. Which statement about standard servings matches the Delaware manual?
Correct answer: A 12-ounce beer, a five-ounce serving of wine and a shot of 80 proof liquor carry about the same alcohol
What counts is how much is consumed, not what form it comes in. Specialty cocktails are the exception, since one can hold as much as several ordinary servings.

5. How long does the Delaware manual say alcohol takes to reach the brain?

6. May a Delaware driver drink an alcoholic beverage while operating a vehicle on a highway?

7. According to the Delaware manual, what actually brings a person's blood alcohol level down?
Correct answer: The passage of time
Coffee, fresh air, exercise and cold showers accomplish nothing at all. Only waiting reduces the amount of alcohol in the blood.

8. What effect does eating have on alcohol in the body?
Correct answer: It slows how fast alcohol enters the blood but will not stop someone getting drunk
Starchy items such as bread, pretzels and crackers delay absorption. Stretching out the interval between drinks works better, and neither one prevents intoxication.

9. Which blood alcohol reading is conclusive proof that an adult Delaware driver is under the influence?
Correct answer: .08 or higher
A reading at or above .08 settles the question, and so does any illicit or recreational drug found in the driver. Someone may still be charged below that figure.

10. For a first impaired-driving conviction with a reading below .15, how long does the Division take the license?
Correct answer: 12 months
The first-offense loss scales with the reading: twelve months below .15, eighteen months from .15 to .19, and twenty-four months at .20 or above or where the test was refused.

11. How long is the revocation for a first zero tolerance offense in Delaware?
Correct answer: Two months
Anyone under twenty-one who drives after consuming alcohol loses the license for two months on a first offense, and for at least six months and up to a year on any later one.

12. How does a drinker's body weight affect their blood alcohol concentration?
Correct answer: A lighter person reaches a given level on less drink than a heavier one
The manual notes that it takes roughly half as much for somebody of a hundred pounds to reach a stated level as for somebody of two hundred pounds.
