I committed a hit and run now my car has been towed "for evidence". I want to know what my next step should be?

I am a CA lawyer.  I practice civil law.  Whenever I get a call that involves a criminal component, I will consult with a criminal lawyer.  You should be doing the same thing.  Look on Attorney Pages web site for a criminal lawyer in your area and set up an appointment.  Do this before doing anything else.  It may cost some money, but in the long run, it is going to be money well spent. 

Whether you were on policy or not does not matter. If you committed hit and run you will be responsible. If you are charged with some sort of criminal matter, you can either hire a public defender if you can not afford a lawyer or hire your own. Do you have a police report? If not, get one. Police will decide whether it is your fault or not. DMV might take separate action. Consult a local lawyer who deals with such matters.

There are two separate issues here.  If the accident wasn't your fault, and the report supports that, then the accident can't be held against you.  However, with respect to the hit and run, that constitutes a criminal action regardless of fault.  You will want to consult an attorney to minimize the consequences.
