Why drinking is dangerous — Montana Permit Test
Why drinking is dangerous on the Montana permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
No one can drink alcohol and drive safely, and new drivers are more affected by alcohol than experienced drivers because they are still learning to drive.
Alcohol is involved in about 40% of fatal crashes, and a new driver has the least skill left over to lose.

On the test
Why are new drivers more affected by alcohol than experienced drivers?
They are still learning to drive. Alcohol is involved in about 40% of fatal crashes, and a new driver has the least skill left over to lose. Montana Driver Manual, p.71: “New drivers are more affected by alcohol than experienced drivers because new drivers are still learning to drive.”
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.
