Yes. Illinois allows DUI court supervision one time per lifetime, in any jurisdiction. Once granted, the defendant is forever ineligible for supervision on any future DUI in Illinois. That is why the first case matters so much. Successful completion avoids a conviction on the driving record, but a second DUI arrest, even decades later, cannot receive the same benefit. A subsequent arrest is treated as a mandatory conviction disposition and often triggers enhanced penalties. A Chicago DUI lawyer explains this permanence up front so the decision to accept supervision is made with the second-strike consequences fully understood, not just the short-term relief.
