Hi,
A few days ago, I parked my car on a street in the Westminster area on a Sunday. While parking, I checked the sign on the opposite side of the street, which stated that parking restrictions applied only from Monday to Friday. When I returned, I found that my car had been issued a fine. I noticed that the parking restrictions on the side of the street where I had parked were different and required a residents’ permit. I made this mistake for two reasons: first, the most visible sign from where I parked was the one on the opposite side of the street, and I was not aware that parking restrictions could differ between the two sides of the same road; second, the residents’ permit sign for my side of the street was positioned further down the road and was not visible from where I had parked.
Is there any way to challenge this penalty?
