It was stating that i will receive a some fines .This was his first offence in his life. So i want to know that what is this will be called : a serious crime or felony or misdamenor or violation or crime or offence??

This was happen in PA. And also i want to know that this will affect his criminal back ground?? Or this will be placed in his crime record or what?? Its urgent...plz guys reply. Ur help will be appreciated. thanks

Make sure you or he hires counsel (or at least a committed public defender) to try to keep this off the record eventually--jail time is not likely going to occur if his record is clear now. But having that arrest and/or a conviction on the record will make job-hunting etc. more difficult. Often this could be negotiated down to some kind of court supervision, a dismissal etc.
