Practice lights, arrows and pedestrian signals, with questions based on the Missouri Driver Guide.
A green or flashing yellow arrow
Stop and wait for the signal to change, and be ready to yield to pedestrians.
At night or during emergencies
Flashing signals may appear during emergencies, at night, in low traffic periods and at special events.
Yes, if set by the city
A city's or county's traffic rules bind you just as the state's do.

Wait for a gap in oncoming traffic
A circular green or flashing yellow arrow lets you turn only after an adequate gap appears.
At the stop line
A line beyond the sign still marks the place you must stop.

We wrote these practice questions from the facts in the Missouri Driver Guide (Revised August 2026 (cover), read 2026-11-08, plus the Department of Revenue page on the Graduated Driver License Law edition) and from official sources on road signs. Every answer links to its source, so you can check it and read more.
DMV Decoded is an independent guide, not a government agency. This practice test is not connected to the Missouri Department of Revenue, and your actual test will have different questions. Study the handbook, and check the agency's website for current rules.
