In Iowa as of 2025, the law allows drivers to make a right turn at a red light after coming to a complete stop, unless there is a posted sign prohibiting such a turn. The Iowa Code stipulates that vehicles facing a steady circular red signal must stop, but they may cautiously enter the intersection to make a right turn from the right lane or another lane designated for right turns. This right is subject to a few important restrictions. First, the driver must yield to all other vehicles and pedestrians lawfully within the intersection or crosswalk. Any turn made must be done in a manner that does not interfere with the safety and movement of pedestrians or other traffic proceeding appropriately through the intersection.
If there is a sign posted at the intersection explicitly prohibiting a right turn on red, the driver must obey the sign and wait for the traffic signal to turn green before proceeding. Local governments in Iowa retain the authority to place such restrictions at specific intersections where safety concerns justify extra caution.
Additionally, the Iowa driver’s manual emphasizes that drivers should only proceed with a right turn on red when it is clear and safe to do so. The responsibility for making a safe turn remains with the driver, even if no signage prohibits the maneuver. If a right turn on red results in a crash or endangers pedestrians or other vehicles, the driver can be held legally responsible for negligence and any resulting damages. Thus, even when making a lawful turn on red, vigilance and consideration for all users of the road are required at all times.
There are also specific considerations in Iowa for right turns at intersections with bicycle lanes or increased pedestrian presence. Before turning, drivers should check for cyclists and yield to those lawfully in the intersection or crosswalk.
Iowa’s right turn on red rule in 2025 allows the maneuver statewide unless otherwise indicated by signs. Drivers must always come to a full stop, yield appropriately, proceed with caution, and be alert to pedestrians and cyclists. Failing to follow these rules can result in traffic citations or, in the event of an accident, liability for damages and injuries.
