I had an incident with a car today. The incident was not the worst, but bad enough. (I will post it later). However, I have some suspicion that the vehicle in question was not taxed and possibly not insured. Is there any way that I can legally find this out? Can I ask the police to investigate this? The incident was not serious enough to report it directly, but I feel that even if I suspect that the car was not insured then I have a duty to report it.
