It was only in August that the Secretary of State for Transport approved a suspnded bay sign for Barnet Council. Before that they didn't have one and so every parking ticket for a suspended bay or space could be contested. Now they do have one but it doesn't look like the one above which was erected on Saturday.
Firstly that is insufficient notice. If you had gone away for a long weekend you could have been ticketed before you got back. 5 days is seen as the bare minimum for suspension except in an emergency.
This is what the sign should look like.
There is no mention in the authorisation that gaffer tape is an acceptable material.
The sign should be in 3 parts so that once folded and mounted it can be seen from both sides of the suspended section. It should really contain details of exactly what section of road is suspended (this cannot be done by the use of cones as in this instance as they tend to "walk" along the road) and there shouldn't be an advert for the surfacing contractor on the sign although there should be a telephone number to call in case of query. The sign in this case is within a residents' bay that holds a dozen cars. How much is suspended? probably only about a 5m section but you could argue it is the whole bay. We'll see what traffic wardens make of it and then NSL will get yet more representations to deal with from Mr Mustard which they will doubtless reject. No wonder Appeals to PATAS have risen so much.
The parking contractor should not be left to erect their own signs as appears to be the case here as the result of any slackness on their part is a PCN for an unsuspecting motorist.
