Get yourself to safety, call 911, and get medical attention even if you feel okay. Then, before you give any recorded statement to an insurance adjuster, talk to a lawyer.
Here is what that looks like in practice. If you can move, get off the road. Call the police so there is an official report, which matters a lot in San Diego where drivers often claim they never saw the rider. If your phone works, take photos of the bikes, the cars, the intersection, skid marks, and your gear. Get names and numbers from anyone who saw what happened.
See a doctor fast. Adrenaline hides injuries, and motorcycle crashes can cause internal harm, neck injuries, and back injuries that show up days later. Gaps in treatment give the insurance company an excuse to pay less.
A word on fault. California is a pure comparative-fault state, so even if you were partly at fault, you can still recover, though your share is reduced. Adjusters know this and will try to pin blame on the rider. You generally have two years to file an injury claim under Code of Civil Procedure section 335.1, but if a city or public agency is involved, the deadline to file a claim can be much shorter.
This is general information, not legal advice, and every case is different.
