DUI Laws in Illinois

DUI and ignition interlock device (IID) regulations vary significantly across the United States, reflecting a patchwork of state-specific approaches to addressing impaired driving. Each state has different criteria for the installation of IIDs for DUI offenders, the duration of IID installation, procedures for IID removal, and penalties for tampering with the device. To ensure compliance with local laws, it is crucial to check with your state officials and continue reading relevant resources on the webpage for the most accurate and up-to-date information.

What to Know
  • Your license will be confiscated immediately if your BAC is above .08% or you refuse a BAC test, even before any criminal trial.
  • You can drive under a temporary permit for 45 days, during which you can request a hearing to challenge the suspension. If no hearing is requested, the suspension begins on the 46th day and lasts for 6 months, with the option for first-time offenders to request a Monitoring Device Driving Permit (MDDP) after 30 days.
  • After the suspension period, you will be required to install a Breath Alcohol Ignition Interlock Device (BAIID), even if it is your first offense.

Administrative License Revocation (ALR) Procedures

llinois is one of 42 states that has implemented ALR which means that your license will be confiscated immediately if your BAC is above .08 OR if you refuse a BAC test. Your license will either be suspended or revoked at that point, even though you have not been officially convicted in a criminal trial.

You will be given a 45-day grace period during which you can drive under a temporary driving permit issued by the officer at the scene. During that time, you can request a hearing to challenge this case. This case will be heard by an administrative law judge. If you do not request a hearing, your license will be automatically suspended on the 46th day for 6 months, although first-time offenders can request a Monitoring Device Driving Permit (MDDP) after 30 days. After the suspension period, you will be required to get a Breath Alcohol Ignition Interlock Device (BAIID).

Remember that this is separate from the judicial case, with separate authorities and rulings. This can significantly influence the judicial procedures, but you must act very quickly if you wish to challenge this.

Judicial Procedures

In Illinois, the drunk driving law prohibits a person from driving when they have a BAC of .08% or higher. Courts are required to order the installation and monitoring of a BAIID for any driver whose BAC levels are .08% or higher, even if it is your first offense.
