Yield to Emergency Vehicles
You must yield the right-of-way to any police vehicle, fire engine, ambulance, or other emergency vehicle using a siren and red lights. Drive to the right edge of the road and stop until the emergency vehicle(s) have passed. However, never stop in an intersection. If you are in an intersection when you see an emergency vehicle, continue through the intersection and then, drive to the right as soon as it is safe and stop. Emergency vehicles often use the wrong side of the street to continue on their way. They sometimes use a loudspeaker to talk to drivers blocking their path.
You must obey any traffic direction, order, or signal given by a traffic or peace officer, or a firefighter even if it conflicts with existing signs, signals, or laws.
It is against the law to follow within 300 feet behind any fire engine, police vehicle, ambulance, or other emergency vehicle with a siren or flashing lights (CVC §21706).
If you drive for sight-seeing purposes to the scene of a fire, collision, or other disaster, you may be arrested. Casual observers interfere with the essential services of police, firefighter, ambulance crews, or other rescue or emergency personnel.
