Hi All,
Good News the PCN has been canceled
"How do you like those Apples? After carefully considering your case, and without prejudice to our position, I have decided to use our discretion to cancel this PCN. This PCN was issued because the vehicle was observed and recorded by an unattended camera, ignoring a ‘No Motor Vehicle’ except buses, taxis, and permit holders’"
Further down the email they did say that warnings are displayed all along the road. This in fact is not true as there were no warnings display except at the Width restriction.
But hey it's a good result.
