1. Accelerate to race ahead of the emergency vehicle
2. Maintain current speed and lane position regardless of the emergency vehicle's path
3. Proactively yield right-of-way by changing lanes, slowing down, or pulling to the right edge
4. Apply sudden maximum emergency braking in the middle of the lane
