I think it's similar round here Chris but I forget the details now. I just find it all a tad pedantic to give people who need it free parking, then complicate it for them with various restrictions, then give out parking tickets if they get it wrong!
Mind you, the yellow line thing is a bit of a grey area don't you think? It should either be safe to park somewhere or not safe. If not, then no-one should really be allowed to cause a problem or obstruction. I think the parking rules need a major overhaul in this country, like the one being sought for hospitals whose car parks have made millions in the last year! Quite often, it's independent, private companies making a fortune out of people's misfortune and misery. Hospitals in Scotland and Wales don't charge for parking... quite right too!
Sorry, I'll put the soapbox away now :Hear_No_Evil_Monkey:Speak_No_Evil_Monke:See_No_Evil_Monkey_
