58K pound sand truck to test their runaway truck arrestor

[tonyfoale]

Many decades back there was a proposal for an arrestor that was carried on the truck. Essentially it was like a roll of canvas fixed to the chassis ahead of the rear wheels. IIRC it was driver controlled, in the event of brake failure it was deployed. It unrolled and found itself under the rear wheels. It would take some very tough material to survive a stop like that, which is probably why we do not see it in general use. Or is it?

Tough indeed! Recalling aftermath to what occurred when a webbed tie-down wound up a trailer tire; stripped tire off that rim, crumpled the fender.
