Whats the deal with salvage titles in CA?

Ive heard so many different opinions and “facts” on If you can drive/own/buy a salvage title car in CA and i cant seem to get a straight answer.

Can i buy a car from facebook marketplace own it and drive it if it is a salvage title

(And can i insure it)

No one seems to be able to give me a good answer
