Free Traffic Legal Advice

Hi

I’d appreciate advice from those familiar with Enfield PCNs and contravention 52M.
My brother received a PCN from the London Borough of Enfield for 52M – Failure to comply with the prohibition of motor vehicles at Montagu Gardens N18 (ANPR).
Date/time: 07/01/2026 at 21:19.
This was my first time driving through this location, and it was dark. The approach appears to be a normal residential road, with parked cars and vehicles visible coming from the opposite direction. There is no physical barrier or clear advance indication of a prohibition.
The “No motor vehicles” signs appear to be placed only at the pinch point and are side-mounted, competing with other signage (bollards, height restriction signs, etc.). By the time they are clearly visible, a driver is already committed with no realistic opportunity to turn back.
I’ve attached a Google Street View image showing the approach.
My questions:
Are there reasonable grounds to challenge this PCN on signage adequacy/clarity, especially at night?
Has anyone had success appealing this location?
If I appeal, do I lose the discount?
In practice, is it worth appealing or safer to pay the discount?
Thanks in advance for any advice.
