Some more semi-scientific research in EMS…
I wonder what the effect on the siren tone is on the driver of an emergency vehicle?
My anecdotal observation is that three things tend to speed drivers up- the yelp setting, the phaser/piercer setting, and moving the selector back and forth. Seems like the wail setting is not as agitating for the driver.
I’ve noticed that if the siren operator on a fire truck is methodically running the siren up and down, as opposed to ‘standing on the Q switch, the fire truck seems a little more methodical in their movements through traffic.
I’ve also noticed that LEO vehicles traveling with a siren set on wail do not seem to be driving as fast as the ones with sirens set on yelp.
Maybe this is something that GEOTAB could gather data on.
