243. DO NOT stop or park
• at or near a bus or tram stop or taxi rank
• opposite or within 10 metres (32 feet) of a junction, except in an authorised parking space
• opposite a traffic island or (if this would cause an obstruction) another parked vehicle
Which makes it fairly clear that parking near a junction or bus stop or opposite traffic islands is not a good idea.
Bexley council in its wisdom has seen fit to break all three safety rules - but it provides another revenue stream which takes priority over road safety.
