From the article above the Ohio Supreme Court basically said that any officer of the law, having been trained by their academy, can use visual estimation as probable cause ticket someone. The court also said that there is no need for independent verification of that fact.

What does that mean? The officer can write a ticket for speeding without having independent evidence provided by radar or whatever device.

Quote from the article:

Supreme Court Justice Maureen O’Connor said “Rational triers of fact could find a police officer’s testimony regarding his unaided visual estimation of a vehicle’s speed, when supported by evidence that the officer is trained, certified by (the Ohio Peace Officer Training Academy) or a similar organization, and experienced in making such estimations, sufficient to establish beyond a reasonable doubt the defendant’s speed. Independent verification of the vehicle’s speed is not necessary to support a conviction for speeding.”

Case is Barberton vs. Jenney
