Illinois Impaired Driving Laws and Penalties

Driving under the influence is a crime.  Aside from concerns for the personal safety of yourself and others, there are severe legal penalties and economic consequences if convicted.  It is important to know that the DUI criminal charge is prosecuted in court and driver’s license sanctions are administered by the Secretary of State’s Office.

Penalties for DUI in Illinois vary depending on the circumstances of the arrest and conviction. These circumstances may include the driver’s age, the driver’s BAC level, whether the driver was transporting a child under age 16, and whether the driver has previous DUI convictions.

An example of penalties for DUI convictions are listed below.

The mission of Mothers Against Drunk Driving is to stop drunk driving, support the victims of this violent crime and prevent underage drinking.

Originally, the mission of the SADD chapter was to help young people say "No" to drinking and driving. Today, the mission has expanded. Students have told us that positive peer pressure, role models and other strategies can help them say "No" to more than drinking and driving. And that is why SADD has become a peer leadership organization dedicated to preventing destructive decisions, particularly underage drinking, other drug use, impaired driving, teen violence and teen depression and suicide.
