The DUI Law in Illinois
Drunk driving is charged as DUI in Illinois, at a blood alcohol level of 0.08 or more.
Driving in Illinois is consent to a breath or blood test when an officer has cause to suspect DUI; the license case that follows a refusal or a failed test is run by the Secretary of State, separately from the criminal case.
Illinois sets no time limit on prior offenses: every earlier conviction counts toward a repeat charge.
