California’s gas prices are set to increase yet again due to a follow-up increase as part of the state’s 2017 gas tax hike.

Prices at the pump are set to increase by 5.6 cents per gallon across the Golden State on Monday. With the new bump, California’s gas tax now equates to 47.3 cents for every gallon of gas pumped.

The gas tax hike initially brought a 12 cent-per-gallon hike to gas prices in November 2017, shortly after the law’s passage.

According to AAA, the national average price of gas per gallon was $2.716 on June 30. In California, the average was $3.754.

Starting July 1, 2020, the gas tax will be increased to keep pace with California’s Consumer Price Index.

Proceeds from the gas tax hike are meant to fund local and state road infrastructure improvement projects.

In 2018, Californians rejected an effort to repeal the gas tax hike.
