ROCHESTER, PA - A Pennsylvania man is using a global positioning device in his company vehicle to appeal a speeding ticket, according to the Beaver County Times.

David Riesmeyer, of New Brighton, was ticketed for allegedly driving 64.5 mph in a 50 mph zone in Rochester on June 15. According to the Times, the officer who ticketed Riesmeyer used a stopwatch-like device to calculate his speed between two painted lines on a roadway. However, Riesmeyer said the GPS recorded his speed every three seconds and shows he was driving only 57 mph.

Pennsylvania state law says a motorist must exceed the speed limit by at least 10 mph to get a ticket, if police aren't using radar on a road with a speed limit less than 55 mph, reported the Times.
