I almost got pulled by a parking warden a few years ago when I parked at the kerb of an on street disabled row of spaces. With in a few seconds of pulling up the warden was on my widow before I could even get the badge out, I opened the window and with that he could see the adapted control on my steering wheel, he didn’t say a word other than “Oh, so sorry, carry on, good day to you sir” and walked off.
That time I was sat in the car so they couldn’t see me but a few years before that I had a parking warden waiting by my car that had the BB displayed and when I returned the moment he seen me coming he walked off.
I found it satisfying they do check and would not mind showing them the picture on the back of the badge if needed.
Apart from that I had many folk stop and ask if I needed a hand to get my scooter into the boot of the car in the days before I had an hoist but now they just ask about the hoist. ?
