The Georgia Legislature gave final approval Saturday in a special session to the month-long gas tax suspension, which Gov. Sonny Perdue ordered into effect last week to help give motorists a break at the pump.
The measure waives the state's 7.5 cents per gallon tax on gasoline and its four percent sales tax on the product through September 30.
The step is expected to save motorists 15 cents a gallon.
The state will lose $75 million in gas tax collections during the month, but Perdue said it will use surplus funds to offset the loss.
