SB1591 amends the Illinois Vehicle Code to create a new category of vehicle called a “leader-follower work zone vehicle.” The bill defines this as a motor vehicle used with another vehicle in a highway construction or maintenance zone, equipped with an automated driving system and remotely connected to another vehicle so the two can move in a coordinated or controlled way within the operator’s line of sight. The measure is aimed at work-zone operations and is intended to support safer movement of vehicles and equipment in active construction or maintenance areas.
The bill also creates an explicit exception to Illinois’ “following too closely” rule for these leader-follower work zone vehicles. In addition, it authorizes the Illinois Department of Transportation and the Illinois State Toll Highway Authority to implement these systems in zones under their jurisdiction as a worker-safety measure. The bill states that the operator of the leader-follower vehicle is deemed the driver and operator of the vehicles used in the safety system, and it makes these vehicles authorized vehicles in highway construction or maintenance zones. The bill is effective immediately if enacted.
Impact
If enacted, SB1591 would modify the Illinois Vehicle Code by adding a new statutory definition and a new section specifically permitting leader-follower work zone vehicle systems. It would carve out an exception from existing spacing and following-distance requirements for these vehicles and give IDOT and the Toll Highway Authority express authority to deploy them in work zones. The practical effect would be to facilitate use of automated or semi-automated convoy-style equipment in road construction and maintenance operations, while clarifying legal responsibility for the operator.
Sentiment
Based on the bill text and the absence of recorded committee testimony or votes in the provided materials, the overall sentiment appears neutral to supportive of innovation in work-zone safety. The bill is framed as a worker-protection measure and does not show any documented opposition in the available record. Its introduction suggests interest in modernizing transportation safety practices through automated vehicle technology.
Contention
No committee transcripts or vote history were provided, so no specific objections or amendments can be identified from the record. The main potential points of contention inherent in the bill are the use of automated driving systems in active work zones, the legal exemption from the following-too-closely rule, and the allocation of responsibility to the operator of the system. Any concerns would likely center on safety, liability, and whether the technology is sufficiently reliable for deployment in highway construction and maintenance settings.
