New DUI Laws in Illinois

Effective January 1, 2011, Illinois has amended the Unified Code of Corrections providing that those convicted of a DUI accident that occurred on or after the amendment date where the accident was the proximate cause of great bodily harm or permanent shall receive no more than 4.5 days of good conduct credit for each month of the offender’s sentence of imprisonment.

Additionally, Illinois increases the amount of technology fees from $500 to $750 usually imposed on first-time offenders who are found guilty or who plead guilty to violating the DUI provision of the Illinois Vehicle Code. Also, Illinois adds a ”summary revocation” to the summary suspension procedures. This provides that a person who refuses to submit to alcohol testing following a DUI arrest involving an accident that causes a Type A personal injury (or death) to another will have his or her license revoked summarily on the 46th day following the arrest.

Drinking and Driving Laws in Illinois

The State of Illinois drunk driving laws start with the .08 percentage blood alcohol concentration (BAC) limit.Like all states across the country Illinois prohibits driving with a .08 percent BAC or above. If you are under 21 years of age in Illinois there is a "Zero" tolerance for alcohol and driving. The only exceptions are for individuals who consume alcohol as part of a religious ceremony or in prescribed medicine containing alcohol. Even with the exceptions, driving with a BAC of .08 is the limit in all cases.

How many drinks does it take to reach the legal limit in Illinois? There isn't one calculation that works for all drivers. Variables such as body-fat percentage, age, weight, genetics and number of drinks consumed over a given time-frame all contribute to the DUI formula. Studies have show that some individuals could have as much as a .05 percentage increase in their BAC for each drink consumed. Given that number, it would take very few drinks to become legally impaired in the state of Illinois.
