The new law imposes hefty requirements on cities that want to use the cameras: a full-time police officer must be posted at each camera in operation, a three-year traffic study must be conducted before a camera is deployed, and cities must give speeders “leeway” — 6 miles per hour over in a school zone and 10 mph over elsewhere — before issuing tickets.

The high court typically rules on cases four to six months after oral arguments. The case was heard in January.

Patton said Linndale and Newburgh Heights in his senate district are using officers with hand-held photo enforcement cameras. He said he would rather that local jurisdictions deploy officers in police cars because their visibility reminds motorists to slow down and drive carefully.

Opponents call traffic cameras automated speed traps deployed just to churn up money for government coffers. Proponents, though, say the cameras free police officers to do other work and prompt motorists to change their dangerous driving habits.
