Taken a few days before the incident is this picture of a Strathclyde Police BMW 5 series of the Roads Policing Unit (RPU, “Traffic Cops”) heading westbound on Main Street, Belshotmuir as a Ford Transit Driver Training Unit (DTU) of the Scottish Ambulance Service (SAS) heads eastbound passing the local First Bus Depot.
In reality both are Code 3 models, with the DTU a representation of the real life SF59 LUE, one of a number of rotating vehicles which I used on my Emergency Response/Advanced Driving course based out of Motherwell Divisional HQ.
