My question involves criminal law for the state of: Pennsylvania

First offense. Never even had a traffic ticket. I got caught and I realize now how stupid it was for me to do this. The LPO didn't call the police. They got all my information and said expect a summons for court next month. They said nothing about a letter regarding civil demands for money. What's the next step? Wait for the letter to see what I have to do next or call an attorney first? I know stores try to scam you with the letters asking for money.

I'm just terrified that they will throw the book at me. I'll pay any fine or do any class...I'm just worried about a misdemeanor on my record.
