A Renault Clio was crashed at 70kph into a standard 10m steel lighting column, complete with outreach arm and lantern, courtesy of Sign Post Solutions. This unforgiving assembly was fitted with an energised circuit and a device provided by TOFCO, to demonstrate that successful disconnection and/or interruption of the supply can be achieved and should always be used, even on unforgiving posts or columns. Note the initial impact prior to the column breaking - this likely to be when the worst injuries to vehicle occupants would be sustained.
