Interview Transcript

Scott Michael Dunn: Let’s talk about DUI defense. What are the penalties for a DUI in Illinois?

Joshua Boardman: Classic lawyer answer—it depends. Is it your first DUI? Is it your second DUI? But generally speaking, you’ve got first-time DUIs. You’ll have county jail up to a year and pay fines up to $2,500. Illinois also has, they have court supervision which would be, could be for 12 months, could be for 24 months. Essentially it allows for you to plead guilty but a conviction does not go on your record. So as long as you do not have any new laws violations and you comply with whatever terms of court supervision that was implemented, then you don’t have any conviction on your record.

For subsequent DUIs, the penalties increase. It can involve mandatory minimums as far as county jail time, mandatory requirements for community services, the fines get higher, and if you continue to rack them up or you get into aggravated DUI territory, then you’re actually looking at the possibility of prison time under a class 4 felony.
