when they first started fitting cable barriers in gippsland one of the people installing them told me some states in america were removing them due to motorcycle accidents. up here they make it hard for the cfa fighting roadside fires in summer. you used to be able to pass dual wheeled tractors now your stuck behind them. if a wide load breaks down between sale and bairnsdale the highway is blocked in that direction. same with accidents. there was a transport spokesman on the radio a few years back telling listeners about the protection that was going on the barriers but as nev said it never happened.
