1. What does the manual say about over-the-counter medicines and driving?
Correct answer: They can impair driving and their labels should be checked
Drugs sold without a prescription can impair driving just as prescription ones do. Remedies for headaches, colds, hay fever, allergies, or nerves often bring on drowsiness, so read the label and ask a doctor or pharmacist if you are unsure.

8. Which of these will actually sober up a person who has been drinking?
Correct answer: Waiting for time to pass

10. Why does the manual compare the effect of alcohol on judgment to a sunburn?
Correct answer: Because you only notice it long after the damage is done
Alcohol dulls the very judgment you would use to decide you have had enough, so by the time you notice the effect, it is already too late — just like a sunburn.

11. How long does a DWI conviction stay on a New Mexico driving record?
Correct answer: Twenty-five years
Any DWI conviction remains on the record for twenty-five years, and later convictions bring larger fines, more jail time, and longer revocation.

12. What amount of alcohol does the manual describe as safe before driving?
Correct answer: None at all — no amount is safe
There is no safe amount. Even a single drink can change how you drive, and with two or more in your system you are impaired and can be arrested.
