What driver fitness rules are on the Missouri permit test?

Missouri's driver fitness questions come from its own statutes and the Missouri Driver License Bureau handbook. QuizLane covers 4 Missouri-specific driver fitness items, drawn from 3 distinct source sections, alongside 10 questions on rules that apply in every state.

How many driver fitness questions are on the Missouri permit test?

Missouri Driver License Bureau does not publish a per-topic breakdown. The test as a whole has 25 questions and you need 20 correct (80%) to pass, so driver fitness is worth studying alongside every other topic rather than in isolation.

Are these official Missouri DMV driver fitness questions?

No. These are original study questions written against Missouri law and the official handbook, each carrying the section it came from. They are not endorsed by Missouri Driver License Bureau and are not copies of the real exam.

Do I need an account to practice Missouri driver fitness questions?

No. Practice starts immediately as a guest. An account is optional and only saves your attempt history across devices.

4 questions on Missouri’s own driver fitness rules

These differ from the rules that hold nationally — they are the ones that catch out drivers who studied another state’s handbook.

1. Missouri's driving with excessive blood alcohol content offense includes operating a vehicle with alcohol by weight in the blood of:
- 0.08% or more
- B0.10% or more

Answer: 0.08% or more. RSMo §577.012 makes it an offense to operate a vehicle while having eight-hundredths of one percent or more by weight of alcohol in the blood (based on grams of alcohol per 100 milliliters of blood or 210 liters of breath).
