The First Crash May Not Be the Last: Understanding Illinois Move Over Duties
A collision or breakdown on the shoulder can become a second emergency when an approaching driver fails to slow down or create space. Illinois Scott’s Law requires caution and, when safe, a lane change around covered vehicles and emergency scenes. Beginning January 1, 2026, drivers must also yield to emergency vehicles displaying flashing lights whether stationary or moving, and to emergency workers or pedestrians involved in the scene.
CTA: If you, a family member or a roadside worker was hurt in a secondary collision, request a personal-injury evaluation.
Key takeaways
- Slow down and move over when it can be done safely.
- Covered scenes include police, fire, ambulance, tow and maintenance activity.
- Hazard lights on a stopped vehicle signal an active roadside risk.
- The 2026 change reaches flashing emergency vehicles in motion.
- Secondary crashes may involve several drivers, employers and insurers.
- Video, dispatch communications and electronic data can disappear.
- Safety and medical care come first.
Approaching the scene
| Situation | Safe response |
|---|---|
| Adjacent lane is clear | Change lanes safely |
| Lane change is unsafe | Reduce speed and proceed cautiously |
| Emergency vehicle is moving | Yield as directed by lights and scene |
| Tow or maintenance vehicle | Create space and slow down |
| Disabled vehicle with hazards | Treat as an active roadside danger |
| Limited visibility | Increase distance and anticipate movement |
Why secondary crashes require a separate investigation
People may be outside their vehicles, waiting for a tow or speaking with police. Debris, blocked lanes and bright lights can affect visibility. The approaching driver’s speed, attention and available reaction distance must be examined independently.
Evidence to preserve
- Wide scene photographs and activated lights.
- Dashcam, police, tow-truck and nearby-business video.
- 911 and dispatch records.
- Witness and worker identities.
- Cone, sign and vehicle placement.
- Commercial-vehicle or event data.
- Police and medical records.
- Insurance communications.
The 2026 expansion
Illinois State Police explains that drivers must now yield to emergency vehicles with flashing lights whether stationary or moving, as well as emergency workers or pedestrians participating in an emergency scene. The duty extends beyond the familiar image of a parked squad car.
