Maryland too, cops suck there. what got ya? a marked car, or one of them chargers that look like anyone from this site would drive? all tinted out, chrome rims, nice looking cars, to bad cops drive them.
my advise in this case is, go to court on your court date. lol get there early look for the line of people waiting to talk to the man in the suit, hes the prosecutor, talk to him and if he and the cop agree some of those may get dropped, dress nice and be polite. and if you pulled right over and gave to cop no crap, it all may work out in the end.
i would just never pay/plead guilty to 3 moving violations, they always bend a little, unless you have a real bad record or gave the cop crap.
