Even if only one car is involved?
Indeed. If only one car is involved the police will still be looking at the condition of the vehicle (Tyres, Brakes, et al), the possibility of drugs or drink being used by the driver, mobile phone records (to check if the driver was using one at the time), weather conditions, speed of the vehicle, state of the road surface at the time etc. The basic premise nowadays is that accidents do not just happen .... something/someone MUST have caused it.
Example: When a car drove into a parked van opposite the Kennels a few months back the police breathalysed the driver, had his smashed car taken off for examination by a local garage, measured skid marks on the road (to estimate his speed) etc etc. Finally they photographed the rear of the parked van, which was filthy and decided that since the car was "roadworthy", the driver had no mobile phone, the skid marks did not indicate excessive speed and so on that the cause of the crash was that the van's rear end was too dirty for the oncoming driver to have picked out it's number plate or reflectors in his headlights. They did not show up on the photos taken with a flash. They charged the van driver with failing to maintain his van in a roadworthy condition. £60 fine and 3 points on his licence....... And he was home, in bed, at the time!
In the agricultural world, the term "serviced" is generally confined to what the bull/boar/ram does to the cow/sow/ewe.
I shall be visiting the local VW dealership this morning as they appear to have serviced Mrs DS (#3)s Golf.
And her Handicap is?
