Thank you,
@Incandescent and everyone,
The sign at the location clearly says red route and no stopping allowed, except for loading for up to 20 minutes, without specifying whether this applies only to domestic or commercial vehicles.
As advised, I requested the footage from TFL, and they provided a DVD showing my vehicle. However, the footage does not include the loading time or parking nor does it prove that I exceeded the 20-minute loading allowance.
What should my next steps be in challenging this? What should I include in my response?
I have evidence of a heavy load being collected from the post office.
Your advice would be greatly appreciated.
