Funeral processions

[wanderer2575]

What I don't get is a firetruck in silent pursuit, lights but no siren and driving very fast. Now cops sometimes have to sneak up on the bad boys so I get when I see a police car doing that, but what is a fire going to do, extinguish itself before they get to it?

Maybe being sensitive of the disruption in residential areas or where there is little traffic.  Fire/paramedic trucks often come down my residential road, and many times they hit the sirens only as they approach the traffic signal a block from me.  After going through the intersection, the sirens are off again.
