Flashing Lights Ahead? Illinois Law Requires More Than Slowing Down
An emergency scene can transform traffic in seconds. Illinois’ Move Over Law—often called Scott’s Law—requires caution, a safe lane change when possible and reasonable speed near stationary units. Beginning January 1, 2026, drivers also must yield to authorized emergency vehicles actively working with flashing lights whether stationary or not, as well as emergency workers and pedestrians directly involved in the scene.
CTA: If you were injured in a collision near an ambulance, police vehicle, tow truck or emergency scene, request a personal-injury consultation.
Key takeaways
- Move into a nonadjacent lane when possible and safe.
- If a lane change is unsafe, slow to a reasonable speed and leave distance.
- The expanded duty reaches certain working emergency vehicles even when moving.
- Drivers must yield to emergency workers and directly involved pedestrians.
- Evidence about lights, lanes, traffic and visibility may matter after a crash.
Responding to common situations
| Situation | Required or prudent response |
|---|---|
| Stationary unit with lights | Change lanes safely and reduce speed |
| Lane change is unsafe | Slow down and leave safe distance |
| Working emergency vehicle is moving | Yield when it displays flashing lights |
| Worker in the roadway | Yield and use heightened caution |
| Pedestrian in the scene | Yield and avoid abrupt maneuvers |
What changed in 2026
The law already protected stationary units and emergency scenes. Current language expressly requires drivers to yield to an authorized emergency vehicle obviously engaged in highway work, whether stationary or not, while displaying qualifying flashing lights. It also protects emergency workers and pedestrians directly involved in the scene.
After a collision
Put safety and medical care first
Call 911 when appropriate, follow emergency instructions and do not stand in an active lane to collect evidence.
Document without creating danger
When safe, record the location, lanes, signs, weather, lighting, damage and witness information. Note which vehicles displayed lights and their positions.
Preserve communications
Keep the report, photographs, dash-camera video, medical records, expenses and insurer communications. Avoid posting conclusions about fault on social media.
