Two sweeping air pollution regulations aimed at removing smog-causing diesel trucks from Southern California roadways and warehouses are being released for public review within the next 30 days.
The measures are part of an executive order issued by Gov. Gavin Newsom to have only zero-emission trucks and buses — most would be electric — on the roads by 2045. The changeover would impact 2 million medium- and heavy-duty trucks operating in California, including about 500,000 in Southern California.
