this is very important as i live in an unadopted road and have an abandoned car left in our cul de sac now for over 2 years full of all sorts of things inside right up to the roof, so you ar unable to get into driver's seat, get to hand or footbrake. it has no road tax and dare say no insurance or mot. i know looking on other websites this is a problem for other people living in unadopted roads. council and police have been contacted and no noe wants to know because its unadopted!
to make unadopted roads in residential areas come under the same rules as adopted roads for highway laws especially concering the dumping of abandoned cars which if left on an unadopted road come under no ones jurisdiction for removal including police and council
