Many thanks Bromptonaut, very useful reply. I object to the needless extension of yellow lines which I see as motivated as revenue-increasing rather than road-safety (in this particular instance, at least). But thanks for the ward councillor suggestion - I will take it up..

In this particular instance I don't feel that the lines make the junction any safer at all and I suspect that the many other spots double yellow-lined under the same notice are more motivated by revenue-raising than safety. I spelt out in my submission to the Council the far greater danger facing users of the junction than parked cars on the bend.

Near here there is a busy junction where there are double yellow lines, very sensibly placed so visibility is good, safe for pedestrians and road clear for turning traffic.

But because there is a PDSA clinic there, every day there are two or three cars parked on the double yellows, right up to the edge of the major A road, all displaying blue badges, while the owners have their dogs treated (free, because they're all on benefits) and are too lazy/obese to park 15 yards further away.

(Note that many are fit enough to stand outside smoking till called in so not that disabled) So traffic wardens ignore them, no revenue collected, safety not considered, waste of yellow paint.

I also don't understand your issue with this.

You say you seldom see cars parked where the lines are going, therefore you have some times seen cars parked there.

Yellow lines do not raise revenue, they allow people that park where parking isn't permitted to contribute to the council coffers.
