Traffic crash duties — Missouri Permit Test
Traffic crash duties on the Missouri permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.

On the test
What does Missouri say about leaving the scene of a crash with a parked vehicle?
It is a crime. A parked car has an owner who will come back to it. Driving off is the offense, not the collision. Missouri Driver Guide, p.81: “Even if you have a crash with a parked vehicle, do not leave. Leaving the scene of a traffic crash is a crime.”
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.
