The only thing i have to offer is that on one occasion i was sent a speeding fine that was for my van in a county that i had not been in ,i was also abroad at the time . My registration was on a similar van that was flashed for speeding ,after a telephone conversation they asked me to send in a photo of my van with myself sat in as if driving ,i also sent in copies of my insurance ,log book (V5 )etc to assist with proof of my ownership of the van .I also supported this with evidence of the holiday i was on .
Presumably this was enough to prove i was the legitimate owner of the van ,not the Romany traveler who was photographed speeding in the van with my reg , and certainly not me .
I got a letter through saying that no further action was to be taken
Bit of a faff but it worked for me ,bearing in mind this was from being caught on a camera that took the photo from the front were faces were clearly visible as the driver . ( this is not legal advice but just my experience )
good luck , Julian East Yorks trf
