In Illinois, a driver can keep many types of traffic tickets from appearing on their public driving record - the one that the insurance company uses to set their rates. This type of sentence (it's called court supervision) allows a person to plead guilty to a charge, pay a fine, and earn a non-conviction, no points outcome after a period of good behavior.
But be careful! Court supervision is not a guarantee, the number of times a person can get supervision is limited, and not all tickets will qualify for court supervision. A driver can only receive court supervision 2 times during a 12 month period. And in DuPage County a person can only apply for court supervision by mail once per 12 months - the second one will require the person to hire an attorney or appear in court personally to ask for supervision.
If the person is speeding in excess of 40 mph or greater above the limit, they cannot receive court supervision. Effective July 1, 2013, Public Act 097-0831, also known as Julie's Law, prevents judges from ordering supervision for drivers charged with speeding 31 m.p.h or more on a highway and 25 m.p.h on urban roads.
Hiring a traffic lawyer will be helpful in guiding you through the system. Often they will be able to appear in court for you and help avoid taking a day off of work, as well as keeping the ticket from going on your public driving record.
