I think if your DL would/could have been suspended it would have to have happened already. You made an error, you were penalized by the state/city for that, there is a set fine. (again my opinion only) I really dont think they can change the penalty to be more severe just because you decide to bring it to court. The officer who wrote you the ticket made a decision he thought fit the infraction, which he is trained to do, so I cant see anyone who wasnt there that night over ruling his professional opinion including the judge, unless you have some type of 3 strikes and your out laws.

Although there are no real reasons to be going that fast over the speed limit, it would be beneficial to have a reason when you get to court, it does help a little with the sympathy. Rather than the "umm, because I didnt see a cop" excuse.
