John and his partner Sarah are keen supporters of Midchester City Football Club and were travelling from Midchester to Oldfield to watch their team play in the FA Cup. The distance from Midchester to Oldfield is about 190 miles and John estimated that the travelling time would be about four hours. After they had been travelling for just under two hours they stopped for a break at a service station. On returning to the car they found that they had a puncture in one of the front tyres and so the wheel had to be changed. This took about 45 minutes. Shortly after leaving the service station they were stopped by a police patrol car for exceeding the speed limit. It is also known that: The driver passed a breathalyser test. The delay caused by changing the wheel had made them late for the start of the football match. Three years earlier John had his driving licence suspended for 12 months for driving while under the influence of alcohol. Sarah is a sales representative and has the use of a company car. It was raining heavily at the time the car was stopped.
