What the plods do is irrelevant to your civil claim against this plank of a moton. The police act for the State to prosecute where criminal offences have occurred.
Correct. My mother's car was hit when a lorry pulled out into the side of her to overtake another lorry on a dual carriageway. The driver was found guilty of careless driving but the civil injuries case had to reprove the fault all over again rather than starting from the guilty finding despite the civil standards of proof being less than the criminal.
The police will NOT give the details of the drivers insurers despite the fact that they are required to. They will tell you you need to write in, which you do, but then they ignore you and finally they tell you they can't give the details because of data protection because they are ignorant simpletons.
In my case, even though it was minor, the police phoned me up out of the blue after a couple of weeks to a) check I was OK, b) tell me they had interviewed the driver and taken witness statements and c) give me the details of her insurance company. Which was good because the driver had been ignoring letters asking for the details. The witness statements were freely provided when I asked for them and the only thing they would not provide was the statement taken from the driver.
