Illinois driver’s license law requires most individuals who wish to operate a vehicle on the public roadways of Illinois to possess a valid driver’s license issued by Illinois. (625 ILCS 5/6-101) Moreover, under the Full Faith and Credit Clause of the United States Constitution, Illinois must recognize a driver’s license issued by any other state.
At this juncture, a word about an International Driver’s License is in order. The ones that you buy on the Internet are worthless and afford you no legal protection.
These should be distinguished from the International Driver’s License that the Illinois Secretary of State will issue to a driver from another country who provides proof that they hold a valid foreign license. In reality, what the Secretary of State does is issue the foreign national a temporary Illinois driver’s license that is backed up by a valid license from another country, which is what distinguishes it from the Internet junk.
Back to the matter at hand, let’s suppose you do not have a valid license, either because you never obtained one or the one you had has expired or been canceled for some reason. If you are caught driving, you are guilty of the offense of driving without a valid license.
While somewhat serious, a conviction for this offense will probably not land you in jail. Most prosecutors will in fact dismiss the ticket if you are able to obtain a valid license for court. And even absent that, you are likely to receive court supervision, at least for a first or second offense.
