A man died and his wife was seriously injured following a head-on collision with a police car whose driver was testing a speed measuring device.
The two Lancashire police cars, one tailing the other, were testing a Vascar device, which measures the speed of a moving car. The force hadn't used the device before and was evaluating it.
The couple, Peter and Jean Williams, both retired, were driving their VW Touran on their way to a break in the Yorkshire Dales. When the police cars rounded a bend in broad daylight, the lead car hit the Williams' vehicle.
Peter Williams suffered chest and leg injuries, and died the next day. Jean Williams is alive with multiple fractures and is in hospital.
The horrendous accident happened on the B6254 between Arkholme and Over Kellet, near Lancaster on Thursday 2 November. Locals say that it's a rural road with sudden dips that obscure the view ahead, and on which there have been a number of accidents.
Both the police drivers had completed advanced driving course, although Lancs Police refused to say why such testing wasn't being undertaken on a much safer motorway rather than an accident-prone, narrow rural road.
