Gas is about to get more expensive in the state of New Jersey this October. The state is instituting a 4.3-cent-per-gallon tax hike on Oct. 1 to combat lagging fuel sales.

According to NJ.com, the New Jersey gas tax hike comes just two years after then-Gov. Chris Christie increased gas prices by 23-cents per gallon to aid transportation projects.

Following the 4.3-cent increase, New Jersey drivers will pay a total of 41.4 cents on each gallon of gas and 48.4 cents on each gallon of diesel.

Drivers are buying fewer gallons of gas in New Jersey. Meanwhile, state law requires the treasurer to raise the tax rate annually to pay for road and rail projects around the state.
