Current Law on Right Turn on Red in Iowa (2025)
- Permitted Unless Prohibited: In Iowa, drivers are generally allowed to make a right turn at a red light after coming to a complete stop, unless there is a sign specifically prohibiting the maneuver.
- Complete Stop Required: Before turning right on red, you must come to a full stop behind the white line or crosswalk and yield to all pedestrians and oncoming traffic.
- Cautious Entry: The turn must be made cautiously and must not interfere with other vehicles or pedestrians lawfully using the intersection.
- Local Exceptions: Cities and municipalities can post signs at specific intersections to prohibit right turns on red. Always look for “No Turn on Red” signs, as these override the general rule.
- Not Mandatory: Drivers are not required to turn right on red. You may wait for a green light if you prefer, and you cannot be ticketed simply for waiting unless otherwise posted.
