Just saw this on the morning News, All vehicles required to have tire chains on the road, including SUV.
A couple of thoughts, one is the so called SUV these days are just All Wheel Drive , have no 4-LOW feature for extreme driving condition.
Secondly, when there is compact snow of 8" or more, ( which reached the bumper of some smaller SUV ) nothing will go on a sloped icy roadway.
Of course it could be operator's error ! Back in the days we learned to operate the 4x4 system on the off road course , not only to learn how to use the 4x4 but also to learn the limit of the feature, so no brave soul will attempt the impossibles.
Chains required for SUV......that's a first for our region.
Livegolf, aren't you glade you're not in the Portland area these days ?
