A roadside crash can happen in seconds—especially in Chicago traffic where lanes are tight and shoulders are narrow. Scott’s Law, Illinois’ “Move Over” law, is designed to protect police, firefighters, tow‑truck operators, IDOT crews, and anyone working on the side of the road. If you were hurt in a crash involving a stopped emergency or maintenance vehicle, knowing the law helps you understand fault, evidence, and next steps.
This guide explains what Scott’s Law requires, where it applies, and how it can affect liability and insurance claims after a Chicago crash.

What is Scott’s Law in Illinois?
Scott’s Law is Illinois’ Move Over law. It requires drivers approaching a stationary authorized emergency or maintenance vehicle displaying flashing lights to change lanes when possible and slow down, proceeding with caution. The law is part of the Illinois Vehicle Code (625 ILCS 5/11‑907).
The purpose is simple: give roadside workers and emergency responders a safe buffer so they can do their jobs without being struck by traffic.
Quick summary: what drivers must do
- Move over into a farther lane if it’s safe to do so
- Slow down and proceed with caution if a lane change isn’t safe or possible
- Stay alert for responders, cones, equipment, and people on the shoulder
In real‑world Chicago traffic, this usually means signaling early and changing lanes when you can. If congestion makes that impossible, you must slow down and pass cautiously.
Which vehicles are covered under Scott’s Law?
The law applies to a wide range of vehicles displaying authorized flashing lights, including:
- Police vehicles
- Fire and EMS vehicles
- Ambulances
- IDOT and highway maintenance vehicles
- Construction and road‑work vehicles
- Tow trucks and roadside assistance vehicles
Illinois State Police guidance confirms that Scott’s Law applies to these vehicles when they are stopped and displaying authorized flashing lights.
Where Scott’s Law applies in Chicago
The law applies on expressways, city streets, and any roadway where an authorized vehicle is stopped with flashing lights. In Chicago, this commonly includes:
- I‑90/94 (Kennedy/Edens/Dan Ryan segments)
- I‑290 (Eisenhower)
- I‑55 (Stevenson)
- Lake Shore Drive and major arterials like Western, Ashland, Cicero, and Pulaski
- Construction zones with IDOT or municipal crews
- Roadside tow operations after fender‑benders
If the vehicle is stopped on the shoulder or in a lane with flashing lights, Scott’s Law applies.
Why Scott’s Law matters for crash liability
If a driver fails to move over or slow down and causes a collision, that behavior can be strong evidence of negligence. In a civil claim, the core question is whether the driver used reasonable care under the circumstances. Violating a safety law can support a finding of fault, especially if the crash involves a stopped emergency or maintenance vehicle.
Common Scott’s Law crash scenarios include:
- A driver clips an IDOT truck on the shoulder because they didn’t move over
- A tow operator is hit while loading a car on the Dan Ryan
- A police car is struck during a traffic stop on the Kennedy
In each case, evidence that a driver failed to move over or slow down can help show responsibility.
Chicago‑specific risks: why move‑over crashes happen here
- Narrow shoulders: Downtown expressways and underpasses leave little buffer for stopped vehicles.
- Heavy congestion: Stop‑and‑go traffic creates abrupt lane changes.
- Frequent construction: Lane shifts and short merges reduce reaction time.
- Winter conditions: Ice, snow, and salt reduce traction and visibility.
Because these conditions are common, drivers are expected to be cautious and anticipate roadside hazards.
Evidence that supports a Scott’s Law‑related claim
To prove fault, you need evidence showing where vehicles were, what lights were activated, and how the crash happened. Useful evidence includes:
- Police crash reports documenting the stopped vehicle and flashing lights
- Dash‑cam or traffic camera footage
- Photographs of the scene, including warning lights and lane positions
- Witness statements from responders or nearby drivers
- Vehicle damage patterns showing a failure to move over
If emergency responders or tow operators were on scene, their statements can also help establish that Scott’s Law was triggered.
Evidence preservation tips
Move‑over crashes often involve multiple agencies and vehicles. Evidence can disappear quickly if it isn’t preserved. Helpful steps include:
- Requesting dash‑cam or squad‑car footage early
- Asking for preservation of tow‑truck or work‑zone camera footage
- Taking photos of the scene, lights, and traffic layout
- Saving your own dash‑cam footage
Early preservation can prevent “missing” evidence that may later become crucial to proving fault.
What to do after a move‑over‑related crash (checklist)
- Call 911 and request a police response
- Photograph the emergency/maintenance vehicle and its flashing lights if safe
- Get names and badge numbers of responding officers
- Collect witness contact information
- Seek medical care and document all symptoms
- Preserve dash‑cam footage or request nearby video immediately
Camera footage can be overwritten quickly, especially from private systems. Early action matters.
How insurance companies analyze move‑over crashes
Insurers typically focus on three questions: (1) Was the stopped vehicle displaying authorized lights? (2) Did the driver have room and time to move over? (3) If not, did the driver slow down and proceed with caution? Clear evidence of the lighted vehicle, lane layout, and traffic conditions helps answer these questions.
It’s common for insurers to argue that a lane change was unsafe because of traffic. If that is true, the next question is whether the driver slowed down enough and passed cautiously. That’s why speed estimates, skid marks, and dash‑cam footage matter in these cases.
Shoulder vs. travel‑lane stops: why it matters
Crashes happen both when a vehicle is fully on the shoulder and when part of the vehicle is in a travel lane. In Chicago, narrow shoulders and construction zones can leave stopped vehicles partially in a lane. That doesn’t eliminate Scott’s Law—drivers still must move over if possible and slow down when they cannot. In claims, insurers often focus on whether there was adequate room to change lanes and whether the driver had enough time to react. Clear photos of the roadway width, lane markings, and cone placement can help show what was realistically possible in the moment.
If you were the responder or tow operator
Scott’s Law crashes often involve people working on the roadside. If you were a responder, tow‑truck operator, or road‑crew worker, your claim may involve additional documentation such as work orders, dispatch records, or employer incident reports. Your employer may also have internal policies for preserving scene photos or dash‑cam data. These records can strengthen the liability picture by showing where you were positioned and what safety measures were in place.
Mistakes that weaken a move‑over claim
Insurance companies look for gaps. Common issues include: waiting too long to request video footage, failing to document the flashing lights in photos, or giving a vague description of the lane layout. Even if the other driver clearly violated Scott’s Law, lack of evidence can slow the claim. A short written timeline, clear photos, and prompt medical care help keep the claim focused on the move‑over violation rather than on avoidable disputes.
What if a driver is cited under Scott’s Law?
Sometimes a police report notes a Scott’s Law citation. A citation is not the same as a civil liability finding, but it can still be helpful evidence because it shows the officer believed the driver violated the move‑over requirements. If a citation is issued, your lawyer can obtain the report and use it to support the timeline and fault analysis. If no citation is issued, you can still pursue a claim—liability is based on the evidence, not just the ticket.
Claim timeline: what happens after a move‑over crash
Most claims begin with medical treatment and a crash report. In the weeks that follow, insurers collect statements, photographs, and any available video. If injuries are still being treated, settlement discussions usually happen later, after doctors have a clearer view of recovery and future care needs. While each case is different, early organization—records, receipts, and a clear timeline—helps reduce delays and protects the value of the claim. It also helps avoid disputes.
Keep wage‑loss documentation from employers, save towing and repair receipts, and track out‑of‑pocket expenses (parking, medications, rides). These small items add up, and solid documentation makes them easier to recover.
Injuries common in Scott’s Law crashes
Because these crashes often involve high speed and limited shoulder space, injuries can be severe:
- Head injuries and concussions
- Neck and back injuries
- Fractures and crush injuries
- Shoulder, knee, and hip trauma
- Psychological distress after a sudden impact
Consistent medical documentation helps connect injuries to the crash.
Damages you may be able to recover
A Scott’s Law‑related crash claim may include:
- Medical expenses (current and future)
- Lost wages and reduced earning capacity
- Pain and suffering
- Property damage and related expenses
The stronger the evidence of a move‑over violation, the stronger the liability case.
