I've never noticed sucha chain. Guess I'll have to ask some of my former coworkers that have moved on to that sort of thing....
I would think the driver would know they had a flat by that flopping noise and different driving sensation that clues the rest of us in. |

It's for dragging ignorant children behind the bus. |

The chains are for what the tires miss.

If a kid trys to skip school by ducking under the bus, he'll be chain-whipped into a red pile of mush.
Shhhhhh! Don't tell the libs or they'll ruin it for us. |

You may also see them on Fire trucks and ambulances.
they are snow chains. The driver flicks a switch and they beging to rotate and swing out in a circle. Some are lined up under the tires and others are extended out towards and under the tires. As they rotate they are dragged under and provide traction to the back tires. That way the don't have to stop and install actual cahins per tire. |

We never had those on buses when I was growing up, nor have I seen them in use on any school buses in my area even today. I see the buses wearing snowchains if the weather is that bad, or school is simply closed. |

They hypnotic sound of the chains makes the children more compliant and aids in liberal brain washing.

Geeze - the answers you guys come up with...........
ELECTRIC GROUNDS. In case of lightening, or hitting a power cable. |

+1 We have the drop down snow chains on all our fire apparatus and are constantly having problems with them. |

sight-rail was correct. They are snow chains. See the link for a description of how they work.

It's a kid-net. If the bus driver is running late he disperses the net at about 35 mph near the bus stop and reals in his catch on the run.

Rubber is more of an insulator than a conductor, IIRC. |

They are used as defense against anti-tank weapons.
They copeid it from the Germans in WWII. "It's for the children" |

That's exactly his point, my friend. Rubber isolates the body from the ground... Ergo, no dissipation and no electrocution. Something must be grounded for current to seek its source. High-voltage boots are complete rubber composite, which means you get the "buzz" without the "hangover." If you're in a car and a powerline falls down on it, stay inside and you're safe. Jump out and never touch both the car and the ground at the same time, and you're safe. Put one foot on the ground, you are officially Elmo on tannerite. BTW, are you EVER going to answer my PM? Been waiting 2 weeks. |

Ooops! You sent me a PM?  I don't think I got it!!  ... can you resend? Or send it by email. I'd been looking for an email from you, but didn't want to hassle you. |

The government figures "Well we gotta spend this money on school buses. We'll waste/pocket half of it. But now we need to make each dollar do twice as much. So make the buses twice as useful. The school buses we intend to buy will double up as Minesweepers."

Sometimes they are regular snow chains just hanging on hooks.

Maybe not the same thing but...If you look at a lot of the high efficiency autos they now have low rolling resistence tires. These tires for whatever reason will not dissipate the staic electricity that a moving vehicle builds up so they added what looks like a grounding strap that hangs from the bottom of the car.

Aw shit. Are you kidding? I had like 100 questions I wanted elaboration on for those papers, and have been thinking you were still on vacation. You never got the damned PM? Are you sure? Hamburger balls. OK, I'll see what I can remember and read them all again. They were fairly generic questions, but I put a LOT of effort into that PM. Nuts. I'll get something to you tomorrow. Sorry, bud. I thought you had it and would answer it in your own time. Rats. |

Richard, The "Send & Save Copy" button is your friend. It has been mine in the past, as well.  If someone doesn't get the PM, you've still got a copy of it you can copy/paste from, so no add'l brainpower/memory spent on remembering. Best, Jake. |

learn something everyday here.
WRT to grounding issue....ground straps are as old as cars and recently making a comeback for some reason. Tires don't dissipate the charge, and the charge builds until it jumps the gap to the ground....in a big spark. |
