Should train horns be mounted on emergency vehicles?

This is louder than a siren.

Check the local laws. Train air horns are much louder than regular air horns so they may not be legal on automobiles.

Many emergency vehicles are equipped with L O U D air horns which are used at intersections along with the sirens.
