Re: Dartford Crossing
At one time I was using the Dartford Crossing several times per month, so registered with the auto payments system. On the whole this worked well, except for one return crossing. The ANPR picked up the correct number plate because they managed to send a penalty notice for non payment. This was cancelled however despite requests no explanation was ever provided as to why the system managed to not match the number with the list of those on automatic payment.
