Illinois Proposal Would Require Speed-Limiting Devices for Certain Drivers

SPRINGFIELD — Illinois lawmakers are considering a new proposal that would require certain drivers to install speed-limiting technology in their vehicles as part of a statewide effort to reduce high-speed crashes and traffic fatalities.

House Bill 4948 would create the Intelligent Speed Assistance Program, allowing courts to order some traffic offenders to install a certified device that automatically limits a vehicle’s maximum speed based on posted speed limits. The measure would make participation mandatory for drivers convicted of traveling more than 100 miles per hour on Illinois roads and would also allow judges to order enrollment for reckless driving convictions.

Under the proposal, drivers ordered into the program would be required to install the approved speed-limiting system on every vehicle they own and would be prohibited from operating any vehicle that does not have the technology installed. Drivers who fail to comply with program requirements could face suspension or revocation of their driver’s license by the Illinois Secretary of State.

If approved, the program would take effect January 1, 2027.

Oversight of the program would fall to the state’s Zero Traffic Fatalities Task Force, which would be responsible for approving and certifying speed-assistance devices, establishing safety and tamper-prevention standards, publishing a list of approved manufacturers, and creating rules governing installation, data reporting, and compliance.

The legislation must still advance through committee hearings and receive approval from both chambers of the Illinois General Assembly before it can be sent to the governor for consideration.
