If a judge finds you guilty of Driving While Intoxicated (DWI) or of driving with a BAC of .08% or more, you can't legally drive once the ticket reaches the Department. Your license is suspended, revoked or denied based on your record, points are added, and you're notified by mail.

Put it into practice
