Ambulance chains

Apr 23, 2006

Ever drive behind an ambulance and notice the chains hanging from the rear axel? I’ve always wondered what those were for and today listening to CarTalk they suggested to a guy who was complaining about being shocked by his car to use a ground strap or chains that would drag on the ground to…ground the car. For ambulances, I would bet that being at ground potential is importand for their instruments (EKG?) or perhaps they just don’t want to shock people. Interesting.
