Illinois is taking one of the boldest steps in the country to crack down on dangerous speeders. A new bill would force certain convicted reckless drivers to install speed-limiting technology on every car they own, or risk losing their license for good.
Here is what this could mean for drivers across the state and why other states are watching closely.
What Illinois House Bill 4948 Would Do
1 House Bill 4948, first introduced in February 2026, would establish the Intelligent Speed Assistance Program. 5 The bill, sponsored by State Rep. Martha Deuter of the 45th District, would require drivers whose licenses have been revoked for consistent reckless driving to enroll in the program if they receive a court order to do so. 3 Under this proposal, reckless drivers, especially those caught going over 100 mph, could be required by a judge to install a speed-limiting device in their vehicle. Once installed, this device would automatically cap speed based on the posted limit wherever the driver is traveling.
The device must go on every vehicle the convicted driver owns. 3Drivers in the program would be required to have the device installed on every vehicle they own and drive, and failing to do so could end with their license getting revoked.
11 The organization Families for Safe Streets, which Deuter’s office says inspired the bill, explains that the program would use speed systems involving maps, GPS, and cameras to prevent vehicles from exceeding posted limits.

How the Speed Limiter Technology Works
Think of it like a breathalyzer, but for your gas pedal. 1These devices are similar to the many alcohol ignition interlock device (IID) programs around the country that essentially embed a breathalyzer into a car to prevent drunk driving.
16 The intelligent speed assistance systems use GPS and digitally mapped data to detect the speed limit at a driver’s precise location and cap their speed accordingly. Unlike a simple speed governor that sets one fixed maximum, ISA technology adjusts in real time as you move from a 30 mph neighborhood street to a 65 mph highway. 15 Drivers can also temporarily override the system if they need to speed up to merge onto a freeway. That small safety exception makes the technology more practical for daily driving. 20 The European Union already requires new cars to issue speed warnings when drivers exceed legal limits. 20 As a result, many vehicles in the U.S. already contain dormant ISA technology due to manufacturing uniformity across markets. That means many cars on the road today could potentially be adapted for this program without needing a full hardware overhaul.
Stiff Penalties for Breaking the Rules
Illinois is not playing around with enforcement. Here is what offenders face under House Bill 4948:
- Minimum device duration: At least 12 months, or however long a license was suspended, whichever is longer.
- Cost responsibility: The convicted driver pays for installation and maintenance, unless a court rules they cannot afford it.
- Tampering charges: 1Tampering with or evading the device, or assisting another person to do so, could result in a Class A misdemeanor.
- Additional penalties: 1Failure to follow any of the program’s requirements may result in license suspension or revocation and may include a civil or monetary penalty.
- Proof of compliance: Drivers must prove the device was installed and officially request permission before removing it.
4 The measure tasks the state’s Zero Traffic Fatalities Task Force with overseeing the program. 4 The task force would be responsible for approving and certifying speed assistance devices, setting safety and tamper-prevention standards, publishing a list of approved manufacturers, and creating rules for installation, data reporting, and compliance. 1 The office of the Secretary of State must also approve all necessary rules and regulations, including exemptions for situations like someone who must drive an employer-owned vehicle as part of their job.
Why Illinois Needs This Now
The numbers tell a grim story. 29In 2024, there were 303,913 crashes involving motor vehicles in Illinois, with 1,085 fatal crashes. Speed was a factor in a staggering portion of those deaths. 29Crashes involving speed accounted for 31.1% of total crashes and 45.3% of fatal crashes.
29 The total estimated cost of crashes in Illinois for 2024 was $8.3 billion. 29 Each fatality was estimated to cost $2,009,575. 26 In 2024, reckless driving was reported as the primary cause of 1,254 accidents in the Chicago area alone.
By the numbers: Speeding’s deadly toll in Illinois
Metric Figure Total crashes in 2024 303,913 Fatal crashes 1,085 Speed-related fatal crashes 45.3% of all fatal crashes Total crash cost $8.3 billion Estimated cost per fatality $2,009,575
23 According to the National Highway Traffic Safety Administration, 75% of drivers with a suspended license continue to drive. That is the core problem this bill tries to solve. Simply taking someone’s license away does not stop them from getting behind the wheel. A speed limiter physically prevents the car from going too fast.
A Growing Movement Across the Country
Illinois is not alone in this push. 14In July 2026, Virginia will become the first state in the country to require drivers convicted of extreme reckless driving to install speed-limiting devices in their vehicles.
15 The Virginia law, sponsored by Democratic state Del. Patrick Hope and signed by Republican Gov. Glenn Youngkin, gives judges the option to require devices that limit vehicle speeds when doling out punishments for reckless drivers. 15 The bill passed with bipartisan support. 23 In Georgia, lawmakers passed legislation allowing judges to require speed-limiting technology for drivers whose licenses have been suspended for violations like street racing, making it the second state to authorize this technology. 17 State lawmakers in New York, Washington State, Maryland, Georgia, Arizona, and California have all introduced similar legislation. 23 Washington, D.C. passed legislation in 2024 to require speed-limiting devices for drivers with speeding-related license suspensions. 3 If this bill becomes law, the program would kick in on January 1, 2027, but it still has to survive committee hearings and votes in both chambers before it gets to that point.
The idea of a machine telling your car how fast it can go might feel uncomfortable. But for the families who have lost loved ones to drivers clocking 100 mph or more on public roads, this bill is not about control. It is about survival. 22The Insurance Institute for Highway Safety, the Road to Zero Coalition, Families for Safe Streets, and other safety advocates have urged automakers, regulators, and fleet operators to promote ISA and speed limiters to help address a spike in traffic deaths since 2020. Whether you agree with the approach or not, one thing is clear: states are done waiting for reckless drivers to slow down on their own.
