Ignition Interlock Device Laws in Illinois
Illinois features administrative penalties for drunk driving that are enforced by the Illinois Secretary of State. When you are arrested for a DUI, you will receive an administrative suspension. For a first offense DUI, this suspension lasts 6 months, while a second offense results in a one-year suspension. A chemical breath test refusal can also result in a one-year administrative suspension.
Criminal penalties for a DUI in Illinois may vary based on the details of your case and prior violations. For a first offense DUI, you can usually expect:
- Up to 364 days in prison
- Up to $2,500 in fines and fees
- Mandatory alcohol treatment and addiction evaluation programs
Following a DUI arrest, you are also subject to further administrative penalties including:
First offense
90-day license suspension
Second offense
License cancellation for up to 5 years
Third and subsequent offenses:
License cancellation up to 10 years
Based on the circumstances of your arrest, the court may require the installation of an ignition interlock device (IID). The period of time varies, but ignition interlock devices may only be installed in your car and serviced by court-approved vendors. You are also responsible for all fees, including installation and monthly maintenance.

Statutory Summary Suspension/Revocation
A statutory summary suspension provides for the automatic suspension of driving privileges of a driver arrested for DUI who fails, refuses to submit to, or fails to complete chemical testing. Failure of chemical testing means a driver has a BAC of .08 or more, a THC of either 5 nanograms or more per milliliter of whole blood or 10 nanograms or more per milliliter of other bodily substance, or a trace of other drugs.
Statutory summary suspensions are automatic and effective on the 46th day from the date of the suspension notice. This suspension does not replace criminal penalties for a DUI conviction. An offender may request a judicial hearing to challenge the arrest; however, the request does not stop the suspension from taking effect.
If Illinois drivers refuse to submit to chemical testing in another state, their driving privileges will be suspended. A statutory summary suspension does not apply to a person with a BAC of less than .08. A statutory summary suspension does not apply to a person with a THC of less than either 5 nanograms or more per milliliter of whole blood or 10 nanograms or more per milliliter of other bodily substance unless the person is a CDL holder. If a person has a BAC of more than .05 and additional evidence such as an open container warrants a DUI arrest, the outcome of the court case will determine if penalties apply. If commercial driver’s license holders receive a statutory summary suspension, their CDL privileges will be disqualified for one year for a first offense; a lifetime disqualification applies for a second offense.
A person convicted of DUI whose driving privileges were suspended because of a statutory summary suspension will have that time credited to the minimum period of revocation of driving privileges. The DUI criminal charge is prosecuted and adjudicated in the courts. This charge is separate from the statutory summary suspension penalties, which is the administrative process. For more information on the criminal penalties for a DUI conviction.
A police officer is required to request a chemical test when there is probable cause to suspect DUI is a factor when a crash results in personal injury or death. Drivers who refuse to submit to such testing will have their driving privileges revoked for a minimum of one year.
Drivers who are subject to chemical testing may be liable for the medical costs associated with the blood test (up to $500) if they are consequently convicted of DUI.
A person’s driver’s license may be subject to multiple suspensions or revocations simultaneously. No single suspension or revocation serves to negate, invalidate, cancel, postpone or lessen the effect of any other suspension or revocation.
Failing Chemical Testing
- First offense — Suspension of driving privileges for six months (eligible for a Monitoring Device Driving Permit).*
- Second or subsequent offense within five years — Suspension of driving privileges for one year.
Refusing to Submit to Chemical Testing
- First offense — Suspension of driving privileges for 12 months (eligible for a Monitoring Device Driving Permit).*
- Second or subsequent offense within five years — Suspension of driving privileges for three years.
*A DUI offender who is eligible for driving relief and issued a Monitoring Device Driving Permit (MDDP) must operate only vehicles installed with a Breath Alcohol Ignition Interlock Device (BAIID), unless exempted by employment. The offender is subject to all MDDP rules and BAIID fees.
Field Sobriety Test Suspension
A police officer who has reasonable suspicion to believe a person driving or in actual physical control of a motor vehicle is impaired by the use of cannabis may ask the driver to submit to standardized field sobriety tests.
If a driver refuses or fails to complete standardized field sobriety tests or if the tests disclose the driver is impaired by the use of cannabis, a field sobriety test suspension will be imposed.
Field sobriety test suspensions are automatic and effective on the 46th day from the date of the suspension notice. This suspension does not replace criminal penalties for a DUI conviction. An offender may request a judicial hearing to challenge the suspension; however, the request does not stop the suspension from taking effect.
A person’s driver’s license may be suspended for both a field sobriety test suspension and a statutory summary suspension at the same time.
Refusal or failure to complete field sobriety tests:
- Suspension of driving privileges for 12 months (not eligible for a Monitoring Device Driving Permit).
- Submission to field sobriety tests that discloses impairment:
- Suspension of driving privileges for six months (not eligible for a Monitoring Device Driving Permit).
Judicial Hearings
A driver may request a judicial hearing to challenge a statutory summary suspension or statutory summary revocation within 90 days after the notice date. The hearing must be conducted within 30 days of the request or on the first court date scheduled to consider the criminal charges. Legally, only five issues may be considered:
- Whether the person was arrested for DUI.
- Whether there were reasonable grounds to believe that at the time of arrest the person was driving or in physical control of the vehicle while under the influence of alcohol or other drugs.
- Whether the driver, after being informed of the impending summary suspension, refused to submit to chemical testing.
- Whether, after being advised of the suspension, the driver submitted to chemical testing that showed a BAC of .08 or more; a THC of either 5 nanograms or more per milliliter of whole blood or 10 nanograms or more per milliliter of other bodily substance; or any trace of a controlled substance, methamphetamine and/or intoxicating compounds.
- Whether, in the case of a statutory summary revocation, the driver was involved in a motor vehicle crash that caused personal injury or death.
The suspension/revocation is rescinded if the court rules in favor of the driver. The result of the hearing is entered on the driver’s record.

If a person is driving on a suspended or revoked driver’s license as the result of an Aggravated DUI conviction and is involved in an alcohol-related crash where a death occurs, he/she may be charged with reckless homicide.
Additional Consequences of DUI
- A DUI conviction is a permanent part of an offender’s driving record.

Vehicle Impoundment
The vehicle of any driver may be seized or impounded by local authorities for:
- Committing a DUI while driving privileges are suspended/revoked for a previous DUI or reckless homicide.

Breath Alcohol Ignition Interlock Device (BAIID)
The majority of states, including Illinois, require first-time DUI offenders to have a Breath Alcohol Ignition Interlock Device (BAIID) installed on their vehicles.
Illinois also requires a camera unit on the BAIID to capture the image of the driver as he/she performs the breath test.
On average, approximately 9,600 individuals are driving with a BAIID device installed on their car or truck.
First-time DUI offenders who wish to obtain and are eligible for driving relief during the period of statutory summary suspension are required to have a BAIID
installed on their vehicle.
To be eligible for driving relief, offenders must obtain a Monitoring Device Driving Permit (MDDP), and a BAIID will be installed on their vehicle through the Secretary of State’s office. An MDDP and installation of a BAIID allow offenders to drive anywhere at any time as long as they are driving a vehicle installed with a BAIID. The Secretary of State’s office monitors the BAIID throughout the duration of the permit. The BAIID will alert the Secretary of State’s office if the driver
attempts any incidents of driving under the influence or tampers with the BAIID device.
A DUI offender may decline to have an MDDP and a BAIID and instead choose to restrain from driving during the suspension period. However, an offender who
chooses not to participate in the program and is subsequently caught driving a vehicle during the suspension period is guilty of a Class 4 felony. Additionally, an
offender who participates in the BAIID program and is subsequently caught driving a vehicle without a BAIID device installed is guilty of a Class 4 felony.
A BAIID also is required as a condition of receiving a Restricted Driving Permit (RDP) for a person who has two or three DUI convictions (no time limit between
offenses); or two statutory summary suspensions (as a result of two DUI arrests); or one DUI conviction with a statutory summary suspension from a separate DUI arrest.
An RDP allows individuals to drive on a restricted basis according to their permit.
Individuals who have two or three DUI convictions must obtain an RDP, drive only vehicles equipped with a BAIID and install a BAIID on all vehicles registered
in their name for a period of five continuous years as a prerequisite for full reinstatement of driving privileges. A judge also may require a driver to have a BAIID
installed on a vehicle. In such cases, it is the responsibility of the courts to monitor and record all information, not the Secretary of State’s office.
Drivers with four or more DUI convictions may apply to the Secretary of State’s office for an RDP after serving five years of their revocation. If the RDP is granted, drivers must have a BAIID installed on all vehicles registered in their name for the remainder of their driving lifetime and drive only vehicles equipped with a BAIID.
A DUI offender is responsible for all costs associated with the issuance, installation and monitoring of the BAIID. For a listing of certified BAIID vendors and installation sites, visit www.cyberdriveillinois.com (click Departments, BAIID).
