When an authorized vehicle with sirens and flashing lights approaches, the appropriate response is to pull to the right-hand edge of the roadway. This action ensures that the emergency vehicle can pass safely and quickly. By moving to the right, drivers create a clear lane for the passing emergency vehicle, which is crucial during emergencies when every second counts.
In many jurisdictions, including Illinois, it's a legal requirement to yield to emergency vehicles in this manner. This helps maintain safety for all road users and allows emergency responders to reach their destinations without unnecessary delays.
Pulling to the left-hand side of the road, speeding up to clear the way, or stopping in the middle of the road would create hazards and potentially block the emergency vehicle, which could lead to unsafe situations for both the driver and the responding unit.
