What happens when you're the defendant in a civil suit over a car accident?

In short, I got into an accident May 28th of last year and I was legally at fault. Today I got a copy of some papers filed a few days ago that I’m the defendant of a civil suit.

I’m being told that my insurance company handles all of this, but obviously at this time of night I can’t talk to anyone about it.

I don’t know anything about this kind of thing; can anyone (especially Jerseyans) help me out here?

I know it’s a vague question, but I don’t really have a specific question. I have a million of them. I’m asking for any kind of input, if the mods will allow it.
