I regularly use the straight between Duncton and Petworth.
One of the issues is that the signs simply contradict each other.
Some of the signs say no overtaking whereas other signs and the road markings, say overtaking is allowed – which is it?
In addition, there are too many signs, both highways and private, which may confuse drivers further.
If ever there were a legitimate place for a camera or two (one in either direction) this has to be it.
Due to the dangerous location of the T-junction, a set of traffic lights would also create a much slower speed zone.
