Clear windows and mirrors — Maine Permit Test

On the test
When does the manual say not to use windshield washer fluid?
On a very cold day. The spray can freeze into a sheet of ice on the glass just as you need to see. Maine Driver’s License Manual, p.75: “Keep the washer fluid full. However, do not use washer fluid on a very cold day as the mixture may freeze on the windshield.”
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.
