COLUMBUS: Ohio's highest court has ruled that a person may be convicted of speeding purely if it looked to a police officer that the motorist was going too fast.
The Ohio Supreme Court ruled Wednesday that an officer's visual estimation of speed is enough to support a conviction if the officer is trained, certified by a training academy, and experienced in watching for speeders. The court's 5-1 decision says independent verification of a driver's speed is not necessary."
