Neighbour's rock used to hit my car. Liability?

[Billo]

One of these neighbours has painted his rocks..?

Ouch

I thought this came quite easily to people working in insurance.

I'v enever heard of people putting rocks out on the public grass verges but if I did see this on my road, I'l lose the plot. Nobody has the right to do this.

...happens a lot around here, in that 10m x 3m space you are obliged to leave outiside your house, for parking. Putting rocks to impede it's use is a breach of Planning Regulations, so yes, it is illegal.

OP - get on to the council, planning enforcement.
