All 50 states have "zero tolerance" laws for drivers under 21, with much lower BAC limits than the standard 0.08%.
Lower BAC Limits
Most states set the underage BAC limit at 0.02%, meaning just one drink can put you over the limit. Some states (Arizona, Oregon, Illinois, Alaska) set it at 0.00%.
Penalties
Underage DUI penalties typically include license suspension (3-12 months), fines ($100-$1,000), community service, mandatory alcohol education, and possible jail time.
Impact on Future
An underage DUI can affect college admissions, financial aid, scholarships, military service eligibility, and future employment prospects.
Diversion Programs
Many states offer diversion or deferred adjudication programs for underage first offenders that can result in charges being dismissed upon completion.
