Under Illinois House Bill 4948, repeat reckless drivers face an Intelligent Speed Assistance (ISA) mandate. While designed to prevent high-speed crashes, lawmakers expressed concern that rigid limiters could prevent drivers from safely accelerating to avoid road hazards, potentially trapping them in dangerous traffic situations.

To address the danger of restricted acceleration, the ISA devices are built with a configurable override button. This allows drivers to temporarily exceed the posted speed limit for a brief number of seconds to safely maneuver around messes or get out of hazardous situations.

Other critical details regarding the legislation include:

• The Offenses: Drivers who commit two offenses within a 12-month period for reckless driving or speeding 26 mph or more over the limit qualify to join the program instead of facing outright license suspension.
• The Penalty: Tampering with or circumventing the device is a Class A misdemeanor.
• Implementation: The law was signed by Gov. JB Pritzker and officially takes effect on January 1, 2027.

Illinois new vehicle speed limiting devices may lead to serious accidents or lead to deaths on Illinois roadways.

New research finds that the intelligent speed devices that Democrats approved and signed into law by JB Pritzker, not only could harm the driver of the vehicle that has the device installed, but other innocent drivers on Illinois roadways come January 1, 2027, when the law takes effect.

At issue is the increased potential for fatal and deadly rear-end collisions.

The problem: unexpected braking! Intelligent Speed Assistance (ISA) systems can sometimes misread speed limit signs (e.g., mistaking an off-ramp sign for the main highway) or rely on outdated GPS maps, causing sudden unexpected braking or acceleration limitations. This could lead to a rear-end collision from an inattentive driver behind them. 

The vehicle with the device can suddenly slam on the brakes, causing an another motorist, who is not on the program to get into a major accident, leading to potential
Death.

These devices will be required to be installed in vehicles of individuals who are our accused of reckless, driving, or are caught speeding two times in one Calendar year.

By forcing a single vehicle to strictly obey an identified speed limit, the technology injects unpredictable behavior into active traffic, endangering innocent drivers.

The technology which combines a device known as a speed, limiter and GPS tracking technology to report a vehicle. ‘D location to state authorities, is not fully tested,

Another bad law passed by Illinois politicians.
