How you must stay behind an emergency vehicle in action?

When an emergency vehicle is in action, such as an ambulance, fire truck, or police car with flashing lights and sirens, you should maintain a safe distance and pull over to the side of the road if possible. Stay at least 500 feet behind the vehicle to allow it to maneuver without obstruction. Avoid following closely, as emergency vehicles may need to stop or change direction suddenly. Always yield the right of way to these vehicles to ensure they can reach their destination quickly and safely.
