Missouri Traffic Rule 2025 Update: Understanding the Right Turn on Red Rule

Yes, Missouri law continues to allow drivers to make a right turn at a red light after coming to a complete stop, unless a sign specifically prohibits it. This applies to both standard red lights and steady red arrows-drivers must stop first, yield to all cross traffic, pedestrians, and cyclists, and only proceed when it is safe.

Key Points of the Right Turn on Red Rule

Full Stop Required: Before turning right on red, you must come to a complete stop at the marked stop line, before the crosswalk, or before entering the intersection if no line or crosswalk is present.
Yielding: You must yield to all other vehicles and pedestrians lawfully in the intersection or crosswalk.
Signage Matters: If there is a posted sign stating “No Turn on Red,” you must obey it and wait for a green signal.
Red Arrow Rule: Missouri treats a steady red arrow the same as a red light for right turns; you may turn right after stopping and yielding, unless otherwise posted.
Left Turn on Red: Missouri generally does not permit left turns on red, except in some local exceptions like Kansas City, where turning left from a one-way street onto another one-way street may be allowed after stopping.

2025 Update

There have been no major changes to Missouri’s right turn on red rule in 2025. The process and requirements remain consistent with previous years, emphasizing safety and yielding to pedestrians and cross traffic.
