Hello Everybody, im looking for some advice please. While at work it appears i may have pulled out of a junction turning left, and left my rear wheels in a box junction.
In my defence it was dark and raining and the box junction markings have mostly faded making them difficult to see.i dont have the actual pcn, just a scanned pdf as its issued through work.
My question is how faded do markings have to be in order to form a defence?
These are the images i was sent below


From the images sent i cant actually see the end of the box junction to know if i was in it or not. I visited the site yesterday and took the below images if they would help


PLease bear in mind that i am the van at the top in the PCN images, not the car at the bottom that is CLEARLY in the box junction, and it was dark at the time of the alleged offence.
Also, is it possible that the car below has triggered the contravention, but my number plate has been captured incorrectly?
Because this is all done via a fleet management company they (fleet management) have stated i need to reply within 5 days so any prompt replies would be very welcome, and i appreciate it is a shorter notice that you wonderful people usually require.
Many thanks
