Lawmakers have sent to Gov. Beverly Perdue a bill that would prevent North Carolina's gasoline tax from going down next month.
The House gave final legislative approval Monday night to a Senate measure that would turn the current cap on the gasoline tax at 29.9 cents per gallon into a floor.
That means it could go no lower than 29.9 cents through the middle of 2011.
Perdue's office said the governor is expected to sign the bill into law.
Under the current law, state taxes at the pump won't go down 2 cents a gallon to 27.9 cents on July 1 as expected under the current law. The tax will still be readjusted twice a year based on the wholesale gas prices.
