Sample question from test 3
alcohol
What minimum revocation follows an Illinois driver's first DUI conviction while under age 21?
- A three-month alcohol-trace suspension
- A six-month chemical-test suspension
- Two years
- A one-year refusal suspension
Answer: Two years. A driver under age 21 who is convicted of DUI faces revocation of driving privileges for at least two years when it is a first conviction. Revocation is the specific consequence in this rule, not the suspension wording used for other triggers. Three months applies when an underage driver has any trace of alcohol while operating a vehicle. Six months follows a qualifying chemical test, while one year follows refusal to submit to chemical testing. Keep the driver’s age, conviction status, and first-offense condition together when distinguishing these consequences.
