This DMV Test Simulator is modeled on the Department of Revenue (DOR) written knowledge exam, which has 25 questions; to pass you need 20 of 25 correct (80%). Besides the 25-question written test (20 correct to pass), there is a separate road sign test. It is a mock test: 25 questions, the length of the real test, scored to the 80% pass mark. Answers are marked only when you submit the whole test, then you review every question with its explanation. Every question includes an explanation, so you learn the rule behind each answer - not just whether you got it right.

Want to test yourself first? Take the test above before reading these. Every answer below is checked against the source shown.

1. A pedestrian with a white cane or a guide dog is crossing the street ahead of you. Missouri law requires you to:
- A. Come to a complete stop (correct)
- B. Slow down and pass with care
- C. Honk so the person knows you are there
- D. Drive around the person on the left
Why: Drivers must always yield to people who are blind. When a pedestrian guided by a dog or carrying a white cane is crossing, you must stop completely.

2. You are already inside a roundabout when an emergency vehicle approaches with its siren on. What should you do?
- A. Stop at once inside the circle
- B. Exit at once and pull to the right (correct)
- C. Speed up and circle until it passes
- D. Pull onto the center island
Why: Never stop inside a roundabout. If an emergency vehicle comes while you are in one, exit right away and pull over to the right. If you have not entered yet, do not enter.

- C. To thank a driver who let you merge

Why: Hazard lights warn others that your vehicle is stopped, disabled or a hazard. Rules for using them while moving (for example in heavy rain) differ between states, so follow your state handbook.
