What Constitutes DUI in Illinois?

In Illinois, a person can be charged with DUI if they operate a motor vehicle:

  • With a blood alcohol concentration (BAC) of 0.08% or higher,

  • While under the influence of alcohol, drugs, or a combination,

  • With any trace of a controlled substance (e.g., cannabis, cocaine, or prescription meds) in their system while impaired, or

  • While impaired due to medical marijuana without proper authorization

Illinois also enforces zero tolerance for drivers under 21 and enhanced penalties for CDL holders, accidents with injury, or DUIs in school zones.

Defenses Against Illinois DUI Charges

Many DUI arrests are flawed. Good attorneys investigate the facts and use every available legal defense, including but not limited to:

  • Illegal traffic stop or lack of probable cause

  • Improper field sobriety testing or officer error

  • Unreliable breathalyzer or blood testing procedures

  • Medical conditions or diet affecting BAC readings

  • Mishandled or contaminated evidence

  • Miranda violations and improper interrogation

  • Witness credibility issues

  • We also explore alternatives to conviction such as court supervision, treatment programs, or reduced charges where appropriate.
