[Stumped]

I live in the hospital area and have a garage accessed from the back alley. Not too long ago I missed a vital Blackburn Hospital appointment because I couldn't get my car out of the back due to a skip at one end and some clown parking a van across the other. A white line has recently been painted across access to the back street from Heywood Road, but all too often it is ignored - even though it is an offence to cause an uneccessary obstruction to the highway. The biggest problem on my particular street is caused by two and three car households monopolising parking spaces.
