For those that know pardon the repeat but got reminded of this by a situation am dealing with this morning, not my own fortunately.

How many people cross their safety chains, it's a law in some states.

1. In case of a ball disconnect, the hitch will fall into the crossed chains, and will not hit the road and dig into the roads surface.

2. In case of a ball disconnect, the crossed chains will do a much better job of controlling trailer whipping, compared to the result of a trailer being pulled by uncrossed safety chains.
