Missouri emergency vehicle statutes state the "vehicle while in motion sounds audible signal by bell, siren, or exhaust WHISTLE...."
Any idea what an exhaust whistle is? Is it a train whistle?
In my quest to research this obscure audible warning option, I came across something really neat: air whistles.
Anyone ever see an emergency vehicle/fire Apparatus with an air whistle on it?
Here's a link to the whistles, and the best part:
SOUND SAMPLES of each whistle are listed next to the whistles!!
Enjoy!!
