Health conditions — South Dakota Permit Test

Health conditions 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

Even little health problems like a stiff neck, a cough or a sore leg can affect your driving; if you are not feeling well, let someone else drive.

On the test

What does the manual say about small problems like a stiff neck or sore leg?

They can affect your driving. A stiff neck stops you turning to check the blind spot, and you merge into a car. South Dakota Driver License Manual, p.22: “Even little problems like a stiff neck, a cough, or a sore leg can affect your 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.
