What should you do upon seeing an emergency vehicle with flashing lights behind you on a city street?

When you see an emergency vehicle with flashing lights behind you on a city street, the appropriate action is to drive to the right edge of the road and stop. This response is vital because it allows the emergency vehicle to pass safely and quickly, which is crucial when it comes to responding to emergencies. By moving to the right and stopping, you provide a clear path for the emergency vehicle, minimizing delays and ensuring that emergency responders can reach their destination efficiently.

Continuing to drive straight could obstruct the emergency vehicle, while slowing down and moving ahead may hinder its progress. Turning onto the nearest side street can create confusion and potentially lead to an unsafe situation, as it might not provide a clear or safe pathway for the emergency vehicle. Therefore, the safest and most responsible action is to pull over to the right and stop.
