Geting another violation during the time you are on court supervision can result in your fine simply being collected up to your licence being suspended
That is really what the 2008 amendment in Illinois about zero tolerance was trying to instill.
Your post does not say, but it is routine for the terms of supervision to include staying free from any moving violations until your supervision term expires.
It's not a great idea to represent yourself in court. You do, however, have the constitutional right to do so. I would recommend spending an entire day in the traffic court to observe how judges handle self-represented defendants to get an idea of how irritated they get at amateur lawyering. If you really want to represent yourself, you should purchase an hour of an attorney's time to have her or him coach you on how to handle things.

A better choice is simply to hire an attorney.

Good luck to you.
