SACRAMENTO, Calif. (AP) — California’s nation-leading gas prices are set to climb even higher Monday, when the state gas tax increases another 5.6 cents a gallon.

It’s the latest increase from a 2017 law designed to raise about $5 billion a year for road and mass transit programs.

A 12 cent-per-gallon boost came that November, and voters last year rejected a Republican-led effort to repeal the law. But Southern California voters did recall one Democratic lawmaker who helped pass the measure.

California motorists were paying an average $3.75 per gallon as of late June, far above the national average of $2.71 calculated by AAA .

The gas tax will increase to 47.3 cents a gallon July 1, according to the state Board of Equalization, and continue to increase indefinitely starting next year to keep up with the California Consumer Price Index.

The money is split between state and local governments, with much of going to fix potholes and rebuild crumbling roads and bridges. Some is also going to public transportation, biking and walking trails, and other projects.

Republicans pointed out again that the tax is increasing even as Gov. Gavin Newsom and fellow Democrats complained about high gas prices.

Newsom in April blamed possible “inappropriate industry practices” rather than higher taxes and stricter environmental rules, and California Energy Commission investigators subsequently pointed the finger at “possible market manipulation” by retailers.

The impending 5.6 cents per gallon boost “will make California less affordable and take another $850 million out of our families’ pocketbooks,” said Senate Republican Leader Shannon Grove of Bakersfield. Assembly Republicans floated an amendment to delay the increase, but majority Democrats blocked the attempt two weeks before the increase takes effect.

Here are several other laws taking effect at mid-year:

— California becomes the first state to require physicians, surgeons, osteopaths, naturopathic doctors, chiropractors, podiatrists and acupuncturists to notify patients if they are put on probation for serious misconduct. The 2018 bill by Sen. Jerry Hill, a Democrat from San Mateo, requires the notices for sexual misconduct with a patient; drug abuse; a criminal conviction involving harm to patients; and inappropriate prescribing resulting in patient harm and five or more years of probation. The measure was backed by athletes victimized by former USA Gymnastics team doctor Larry Nassar, who admitted sexually abusing women and girls under the guise of medical treatment.

— Law enforcement agencies will have 45 days to make public body camera footage recorded during an incident causing death or serious injury. The 2018 bill by Democratic Assemblyman Phil Ting of San Francisco has exceptions if the agency demonstrates “by clear and convincing evidence” that release would substantially interfere with an ongoing investigation or violate the privacy of someone in the footage. The law is one response to lawmakers’ concern over shootings of suspects by police. Proponents said the release will help rebuild trust with communities.
