Illinois: Underage DUI
The drinking age in Illinois is 21 and consumption of alcohol by anyone under 21 is illegal with the following exceptions:
- on private, non alcohol-selling premises, with consent of a legal guardian -- for example, with legal guardian’s permission at a party, or
- for religious purposes – for example, drinking wine with religious ceremony.
In Illinois, underage DUIs cause approximately 15% - 17% of the state’s drinking-impaired driving fatalities (though drivers under 21 only account for 10% of drivers). Because underage drinkers cause a disproportionate number of alcohol-related auto fatalities, the standards are stricter and the penalties may be harsher for those under 21.

What constitutes driving under the influence?
Illinois is a zero-tolerance state. If a chemical test determines that an under-21 driver has a blood alcohol content (BAC) above 00.00%, the driver can be cited for driving under the influence.
What are the penalties?
If First Drunk Driving Conviction: If BAC above 00.00% but below .08% - 3-month license suspension. If more than .08% (or more than .05 with additional evidence proving impairment) - minimum 2-year license suspension. imprisonment (up to 1 year), maximum fine ($2,500). (More information: First Offense DUI in Illinois).
If Second Drunk Driving Conviction within 5 Years: If under-21 and if BAC above 00.00% but below .08% - 1-year license suspension. If more than .08% (or more than .05 with additional evidence proving impairment) - minimum 2-year license suspension, imprisonment (minimum 5 days up to 1 year jail) maximum fine ($2,500). (More Information: Second Offense DUI in Illinois.)
What if you refuse the chemical test? First violation — 6-month suspension of driving privileges for refusal or failure to complete a BAC test. Second violation — 2-year suspension of driving privileges for refusal or failure to complete a BAC test. Read about Illinois implied consent laws.
What other charges?
In addition to driving under the influence, an underage drinker may be charged with any of the following:
- distributing alcohol to other minors (were there underage drunk passengers?),
- minor in possession,
- soliciting alcohol,
- child endangerment law violations,
- possession of false identification (was a fake id used to purchase alcohol?), and
- moving and vehicle maintenance violations (what else did the arresting officer see?).
What happens to insurance?
Some insurance companies may terminate a policy after an underage DUI (while others refuse to renew). Most companies simply raise the cost of the monthly premium by $100 to $200 (sometimes higher) for a higher risk policy. The raise usually stays in place for three to five years. You’ll also probably need to furnish the DMV with an SR-22 certificate to reinstate a license after suspension (as proof of insurability). Most insurance companies furnish this form to the DMV. Check with your insurer to see if it performs this service.
