1. A and B are driving their car along a main road when the brakes fail and A loses control of the car. The car goes off the road and plunges down a steep slope where it crashes. A and B are seriously injured, but might have recovered if they had been found and treated promptly. C, who was driving some way behind them, saw the accident and reported it to the emrgency services. The local police sent a car to drive along the relevant section of road, but the driver did not see the damaged car, which was not easily visible without getting out of the police car and looking carefully at the place where it want off the road. It was raining at the time, and the police officer stayed in his car because he did not want to get wet. It was three days later when someone else reported the presence of the crashed car. When the emergency services attended the scene, they found A and B dead from their injuries.

Do the estates of A and B have claims against the Police for negligence?
