How does the court check your proof of car insurance at your court appearance?

When I show her (the Judge) my insurance card and paper work from progressive stating that I'm insured with progressive untill DEC 3, 2009 will she actually look into it at that moment or just look at the documentation and dismiss the case?

I got pulled over three months ago and i didnt have my proof of insurance on me. I have to appear in court tomorrow to show that I had insurance on that night.
