Dangerous health conditions — Montana Permit Test

On the test
What does a person with epilepsy need in order to drive?
A physician's written statement. A seizure at the wheel leaves a car moving with no one in control. Montana Driver Manual, p.73: “A person suffering from epilepsy needs a physician to attest in writing that the person’s condition has stabilized and would not likely interfere with a person’s ability to safely operate a motor vehicle.”
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.
