Deuter filed the legislation in the Illinois House on Feb. 4, 2026, during the 104th session.

The bill, designated HB4948, was passed on May 20, 2026, as part of the general assembly's 104th session.

The Illinois General Assembly website provides this official summary: "Amends the Illinois Vehicle Code. Establishes the Intelligent Speed Assistance Program to supervise the installation and compliance of intelligent speed assistance systems. Sets forth requirements for the Secretary of State upon receipt of notice from a court that a person is required to enroll in the Program. Provides that a person enrolled in the Program shall install a certified intelligent speed assistance system on each motor vehicle owned by or registered to the person and shall not operate any motor vehicle that is not equipped with a functioning, certified intelligent speed assistance system. Provides that if a person fails to comply with the requirements of the Program, the Secretary may: suspend the person's restricted driver's license for a period and, following the period of suspension, permit the person to reenroll in the Program; revoke the person's restricted driver's license and prohibit the person from reenrolling in the Program; or impose a civil penalty. Provides that a person enrolled in the Program shall pay all costs associated with enrollment and participation in the Program, unless the person is found to be indigent. Provides that the Zero Traffic Fatalities Task Force shall certify intelligent speed assistance systems for use in the State and adopt rules and forms for the installation, maintenance, and certification of intelligent speed assistance systems. Sets forth requirements for selling or leasing intelligent speed assistance systems. Requires a manufacturer or distributor of an intelligent speed assistance system to provide support services. Prohibits a person from tampering with, or in any way attempting to circumvent, bypass, or tamper with the operation of, an intelligent speed assistance system that has been installed in a motor vehicle. Requires the Task Force to adopt rules and forms as are necessary to implement the Program. Makes conforming changes in the Code and in the Department of Transportation Law of the Civil Administrative Code of Illinois. Effective January 1, 2027."

Below is an analysis based on the full bill text, which is intended to help clarify the new law’s details.

The legislation establishes an Intelligent Speed Assistance Program, effective Jan. 1, 2027. Offenders designated by court order must install certified devices that automatically cap vehicles’ speeds to match posted limits on all vehicles they own or register, operating only those vehicles so equipped. The Secretary of State is required to suspend the regular license, issue a restricted one linked to program compliance, and may take further action for noncompliance, such as suspending, revoking, or fining participants. Individuals generally pay related costs unless found indigent, in which case an assistance fund may help cover expenses. The Zero Traffic Fatalities Task Force is responsible for certifying devices, establishing standards for safety, data, and support, ensuring statewide availability, and drafting necessary rules and warning labels. Tampering with a system required under the program is classified as a Class A misdemeanor.

Sen. Adriane Johnson (Democrat-30th District), Rep. Angelica Guerrero-Cuellar (Democrat-22nd District), and Rep. Bob Morgan (Democrat-58th District) sponsored the bill, along with support from 18 additional sponsors.

Illinois legislation follows a multi-step process, starting with introduction in one chamber, committee consideration, floor debate, and passage in both the House and Senate before advancing to the governor for signature or veto. The General Assembly works on a biennial timeline; though numerous bills are introduced each session, only a portion make it to enactment.
