In California, what exactly is covered with liability car insurance?

My car is only covered by basic liability insurance required by the state. I was recently in an accident where another vehicle swerved causing me to roll over 5 times into a ditch and total my car. The other vehicle didn't stop but there were several witness' to verify my story. No other vehicles were damaged. What options do I have as far as replacing or repairing my car via a claim etc ?
