- This car park is constantly being used by large commercial vehicles, ie large delivery vans and flat bed trucks which do not in any way fit into the marked bays. The bays just about accept the larger SUV's which are now on the market. I have experienced several "parking dinks", but it is increasingly difficult to pinpoint the culprits. Are there any restrictions to the size of vehicle permitted to park in this area ? Possibly having rule breakers prosecuted ?
