Illinois Breath Alcohol Ignition Interlock Device (BAIID) Program
The Breath Alcohol Ignition Interlock Device (BAIID) is a device that is installed on the vehicles of first-time DUI offenders in the state of Illinois. The device requires the driver to perform a breath test before starting the vehicle, and it will prevent the vehicle from starting if the driver’s blood alcohol content is above a certain level. Illinois also requires a camera unit on the BAIID to capture the image of the driver as they perform their breath test.

The BAIID program is administered by the Illinois Secretary of State’s office, which monitors the device throughout the duration of the permit. Any first-time DUI offender who wishes to obtain and is eligible for driving relief during the period of statutory summary suspension is required to have a BAIID installed on his/her vehicle. To be eligible for driving relief, the offender must obtain a Monitoring Device Driving Permit (MDDP), and a BAIID will be installed on his/her vehicle through the Secretary of State’s office.
An MDDP and installation of a BAIID allow an offender to drive anywhere at any time as long as he/she is driving a vehicle installed with a BAIID. 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 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.
In addition to first-time DUI offenders, a BAIID is also 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. A Restricted Driving Permit (RDP) allows a person to drive on a restricted basis according to his/her permit.

Overall, the BAIID program in Illinois aims to prevent drunk driving and promote safety on the roads by requiring certain DUI offenders to have an ignition interlock device installed on their vehicles. The program is monitored by the Illinois Secretary of State’s office, and there are strict penalties for non-compliance.
What is the cost of a BAIID
The cost of a BAIID in Illinois includes several fees. On average, the installation fee is around $851. The monthly rental fee for the BAIID is around $801. In addition, there is a monthly monitoring fee of $30 that must be paid up front to the Secretary of State’s office prior to the issuance of a Monitoring Device Driving Permit (MDDP). These are average fees and may vary depending on the vendor.
Where can I get a BAIID Device installed
In Illinois, there are several certified vendors that offer BAIID installation services. Some of the certified vendors include Intoxalock, Low Cost Interlock, A Simple Interlock, Smart Start, Guardian Interlock, and AlcoTest Inc. You can find a list of BAIID installation site locations on the Illinois Secretary of State’s website.
How long does it take to get a BAIID installed
According to the Illinois Secretary of State’s office, you must have a BAIID installed within 14 days of issuance of your Monitoring Device Driving Permit (MDDP). If you cannot install the BAIID within the 14-day period, you must call the BAIID Division to request an extension. However, the actual time it takes to install a BAIID may vary depending on the vendor and their availability. It is best to contact a certified vendor directly to schedule an installation appointment and inquire about the time it takes to complete the installation.
How long do I need to have a BAIID installed on my vehicle
The duration for which you need to have a BAIID installed on your vehicle depends on your specific situation. For first-time DUI offenders, the BAIID must be installed for the duration of the Monitoring Device Driving Permit (MDDP), which is typically the length of the statutory summary suspension. For individuals with two or three DUI convictions, a BAIID must be installed on all vehicles registered in their name for a period of five continuous years as a prerequisite for full reinstatement of driving privileges.
A driver with four or more DUI convictions may apply for a Restricted Driving Permit (RDP) after serving five years of their revocation. If the RDP is granted, the driver must have a BAIID on all vehicles registered in their name for the remainder of their driving lifetime.
