How come I see fire trucks with full lights and sirens go through a red light at intersections and then, after they go through, they turn off their lights and slow down?

Sometimes several units are dispatched to the same incident.  The first unit may have arrived on the scene, surveyed the situation, informs the dispatcher that the situation was under control, does not need additional resources and cancels unneeded resources.

Most likely, when you see an emergency vehicle with operating lights and siren go through an intersection and then slow down and turn the emergency lights off, they have been cancelled from the call they were going on.
