Legal Question in Traffic Law in Illinois

Hire a lawyer. You don't know how to handle a radar case because you don't know what the "state" must first prove to make its case (and that's its responsibility) because if it doesn't you can move for dismissal, and then if they have made their case you will need some logical explanation as to (a) why you were speeding, or (b) if you were speeding at all it was nothing that fast, or (c) you were not speeding and the officer mistook you for a speeding vehicle.....

Don't be penny-wise and pound foolish.
