AutoSock is approved as chain substitute for passenger vehiclesOctober 25th, 2012 by travis baker
The in basket: Jim Snyder of Indianola e-mailed me about this time two years ago, as winter closed in, with a question about AutoSocks, an alternative to chains described in a couple of e-mails he had received.
I had never heard of them, and haven’t seen any in use during our few snow episodes here since.
The e-mails included a link to a video of them in use, at http://www.autosock.com/. It shows an elasticized fabric device that fits over the tire like a shower cap.
Jim wanted to know if they are legal here, so I asked.
The out basket: State Trooper Russ Winger of the local patrol office says, “Autosock is approved for use as an alternative traction tire device only for passenger vehicles in the state of Washington. It is not approved for use on commercial vehicles. The list of approved alternative traction tire devices can be found on our Web site at http://www.wsp.wa.gov/traveler/traction.htm.
