On 5th June I was in Leeds, my first visit. Due to a big accident on the M1 I was over two hours late for an appointment and arrived in the midst of rush hour. I followed my satnav to arrive at the address I needed and apparently, although I have no recollection of this, drove in a bus lane. It must have been for a very short distance and probably in a line of other traffic as I do not recall ANY signs.
On receiving the notice I wrote explaining the situation and asked them to confirm that both the notice and the road markings fully comply with regulations. I was apparently in Boar Lane
