Clear view windows — South Dakota Permit Test
Clear view windows on the South Dakota permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules

On the test
Before driving on a frosty morning, what does the manual say to clear?
All windows: front, sides and back. A peephole scraped in the frost leaves the car beside you or the walker behind you unseen. South Dakota Driver License Manual, p.24: “Clear snow, ice, or frost from all windows before driving.”
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.
