OK, so the road close to me into the Olympic Park is no entry other than for buses and cycles. But plenty of cars speed through it as it's a convenient rat run and saves them about five minutes going around a bigger loop.
I raised the issue with Roadsafe and the PC who replied commented
"Please note, having seen the picture the No Entry is conditional as it allows some vehicles not all. It is therefore not enforceable as an endorseable ticket as would be normal for a No Entry sign. It maybe that it is under civil enforcement and would be dealt with by the local council. Local policy would apply".
I replied asking
"Can you just confirm/clarify - are cars allowed to drive through on this road without penalty? To me it looks as if only busses and cycles are allowed to use the road. Are you saying that a car could use the road, despite the no entry sign, without fear of a fine or ticket should they be caught by a policeman?"
He replied "If seen driving in contravention of a traffic sign it is an offence under s.36 Road Traffic Act 1988 by means of Regulation 10 of Traffic Signs Regulations and General Directions. The method it is dealt with is not always the same. Some boroughs in London have chosen that some signs are to be dealt with by civil enforcement while other areas they remain with the police to enforce. Your local SNT will know what there local directions are".
I really don't get this, surely if it's a no entry sign then driving through it should at the very minimum mean a fine? And if it's local policy that the police don't enforce then who does?
