ATLANTA — Many out-of-state motorists who have been busted by Georgia’s “super speeder” law don’t pay up, state auditors found. Georgia’s super speeder statute was approved in 2009 and adds an extra $200 fine onto a ticket for anyone convicted of speeding at 75 mph or more on a two-lane road or at least 85 mph on larger highways. Over the past four years, drivers have run up $10.5 million in past-due super speeder fines, auditors found.
