Vehicle plunges into water — Maine Permit Test

The rules

Once the wiring shorts, a power window cannot be opened at all.

On the test

About how long may a car with closed windows and doors float in water?

3 to 10 minutes. Knowing you have only minutes keeps you from waiting for the car to touch bottom. Maine Driver’s License Manual, p.100: “A car with windows and door closed may float from 3 to 10 minutes.”

How this works

Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.

You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.

Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
