2. Does taking a prescription or over-the-counter medicine excuse impaired driving in a Maine court?
Correct answer: No, it is not a defense and the punishment is the same
The manual says the use of an over-the-counter remedy or a prescribed drug is not a defense in court, and a conviction for driving impaired by any drug brings the same punishment as an alcohol case.

3. Which test does a Maine officer normally administer to measure a driver's alcohol level?
Correct answer: A breath test, unless the officer finds that unreasonable

7. What actually lowers a person's alcohol level after drinking?
Correct answer: The passage of time and nothing else
The liver breaks alcohol down at a fixed rate, so only the passage of time helps; coffee, a cold shower or exercise leave a person awake, wet or sweaty but still impaired.

8. Which effects does the Maine manual attribute to marijuana use by a driver?
Correct answer: Drowsiness, poor judgment of time and space, and narrowed attention
It reports that marijuana can bring on drowsiness and impair judgment of time and space, and that some users focus on a single object while ignoring everything else around them.

9. What happens if a Maine driver refuses an alcohol test after being stopped?
Correct answer: The license is suspended immediately, for as long as six years
