Again with the chains to all vehicles on an app message just now. Seemed to be some individual interpretation of the requirements this morning, depending on who stopped you on the road. I was curtly told "fitting chains to AWD's" and did so. Meanwhile 3 different AWD's went past without being stopped, sans chains. As I left the chain bay, I noticed that the sign was saying 2WD fit chains, AWD recommended. I did pass one Commodore on the way up that had got into strife and had a copper helping him. But on the way back down, the only vehicle in trouble was yet another old Nissan Patrol that had slid into a gutter on the down side.
