According to an article on CNN Money, Ohio issues more speeding tickets than any state in the union.  Congrats Ohio, your number one.

The states that issue the most speeding tickets nationally include Ohio, Pennsylvania and New York, he said.  The average cost of a traffic ticket, including court fees, is roughly $150. You'll pay roughly $300 more in the next three years on higher insurance fees. If you fight the ticket, then add on the cost to hire a lawyer. And of course, you'll have to factor in lost time from work to plead your case.

"It's a big racket -- it's a way for states to make money," said Eric Skrum, communications director for the National Motorists Association.  Many states make it easier to just pay the ticket than fight it. For example, some states allow you to pay the ticket on the spot with a credit card.

Indeed, for many towns, traffic tickets provide a substantial source of their revenue. The town of Waldo, Fla., for example, home of a notorious speeding trap on Route 301 between Tampa and Jacksonville, gets nearly 33.5 percent of its income from traffic tickets, according to Shir Lee Cox, a division manager for the American Automobile Association in Miami. The town of Lawtey, Fla., earns nearly 68.2 percent through traffic fines. As a result, AAA recommends its members use other routes.
