Thanks all for your help so far. Will be submitting the following today:
To Whom It May Concern:
Ref: PCN PN75540198
I make the following challenge:
1. The alleged contravention did not occur as there was no warning signage of a bus lane at the junction. I rely upon:
Traffic Signs Manual, Chapter Three:
https://assets.publishing.service.gov.uk/media/5c78f895e5274a0ebfec719b/traffic-signs-manual-chapter-03.pdf9.3.16. The sign to diagram 962 is most likely to be used where a nearside bus lane is on the
same side of the major road as the side road; in this case the arrow will point to the left.
2. I also consider the white line to be faint and not fit for purpose.
3. I was forced to manoeuvre into bus lane as the vehicle in front braked suddenly as I was turning left onto the main road.
4. I put you to strict proof that the camera used is approved. If you cannot provide this, the evidence is inadmissible.
In light of the above, please cancel the said PCN.
