Abandoned vehicles often get confused with nuisance vehicles. An abandoned vehicle is always a nuisance, but a nuisance vehicle is not always abandoned.
Examples of a nuisance vehicles include, poor parking, causing obstruction or broken down.
Nuisance vehicles will not be dealt with by the council.
Public streets are for the passage of people and traffic and no one has a right to park on any specific part of the highway. You have no right to park your car (or any other possession including trailers, caravans or boats) on the road outside your front door and the council is under no obligation to provide you with a space.
If you own a caravan then our advice is that you should arrange storage on a reputable site in the vicinity.
If you own a boat then our advice is that you should arrange storage at a local sailing club or boat park.
