What is the likely outcome for me of a "disobeying" misdemeanor charge?

I was arrested for "disobeying" because I turned around to avoid a DUI Checkpoint. I was not intoxicated, no sobriety test was performed, but I turned around because I did not want to take the time to go through it and I knew an alternate route. I entered a different road and saw that there were headlights behind me. I foolishly decided that if it was a cop I would just pull into a drive way and let him go by. I did so, it was an officer, and he followed into the driveway and then engaged his lights. I was not aware for sure that he was a police officer until then. Four more officers came, I got out and explained my actions to them, and was arrested for disobeying. I have not been arrested before, so the bondsman told me they would probably not be too hard on me. Also, I don't know if it is relevant, but at no point during the process was a read my rights. (Was not sure what 'Legal Topic this should be placed under)
