The House has adopted stiffer fines on motorists who speed to help shore up Georgia's ailing network of trauma hospitals.
The measure would tack on an additional $200 on drivers who top 85 mph on four-lane roads and interstate highways and those who top 75 mph on two-lane roads. The so-called "Super Speeder" measure passed 113-53 Monday and goes to the Senate.
Sponsors say it could raise more than $30 million each year.
Gov. Sonny Perdue and allies in the House have pushed the measure for three years, saying it would make the roads safer while bolstering the trauma system. House Speaker Glenn Richardson also backed the measure.
Critics say the measure is little more than a new tax.
