what is judicial supervision mean?

I am 20. I was with somone who was charged with a DUI. I was not driving but did have a can of beer (unopened) sitting next to me. Neither one of us blew but both went to jail. I was chaged with minor consumption and illegial transportation and was told by the judge today I will have judicia supervision. I also lost my license for 3 months and have to pay $200.00 fine. This is my first offense.
