I have always been told that the noise it makes prevents motion sickness. Some school buses are starting to have them as well.

They are an antenna for the two way communication radio. Even in areas that have no signal, they can transmit and receive calls through ground penetrating amplification!

Actually they are grounds. Most newer ambulances have automatic tire chains as well, but all have ground chains. As a vehicle drives through the air it gains a static charge. The static builds up since the vehicle is isolated from the ground by the tires. This is what "shocks" you when you get out of your car while touching a metal part. That static shock is enough to damage sensitive medical equipment on ambulances so they have a ground chain to dissipate the static energy to ground.

A lot of power company trucks also have a ground strap which works the same as a ground chain. It dissipates static that build up on the trucks while working around high voltage lines.

I didn't say bucket trucks had them, I said power company trucks. Usually those with electronic equipment installed. And they don't use ground chains, they use a ground strap. It looks like a rubber strap but it is conductive.

Ambulances have had ground chains long before automatic tires chains were common. There is no reason for the automatic tire chains to drag the ground, they are mounted high on the axle.

They are mounted on pneumatic arms on the bottom of the axle....they drag on short inclines like intersections...ambulances DO NOT have ground chains....chains would make for poor grounds anyway! AND power trucks DO NOT have sensitive equipment in them......and DO NOT have ground straps!

They are automatic tow chaos so in case they get stuck up in someone's yard or a muddy road they can be pulled out easily.
