The Ohio Supreme Court on Wednesday upheld cities’ use of traffic camera enforcement for a third time, striking down as unconstitutional legislative restrictions that included requiring a police officer to be present.

The ruling was 5-2 in support of the city of Dayton’s challenge of provisions in a state law that took effect in 2015. The city said it improperly limited local control and undercut camera enforcement that makes cities safer by reducing red-light running and speeding. Dayton and other cities including Toledo and Springfield said the law’s restrictions made traffic cameras cost-prohibitive.

The court Wednesday ruled illegal requirements in the law that an officer be present when cameras were being used, that there must be a lengthy safety study and public information campaign before cameras are used, and that drivers could be only ticketed if they exceeded the posted limit by certain amounts, such as by 6 mph in a school zone.
