What this code means

“Failing to give way to oncoming vehicles”

Code 37 is an on-street contravention from London Councils' national PATROL contravention code list, the standard list used on council and TfL penalty notices across England and Wales, not just London.

Is there a common way to challenge this?

It depends on the facts of your case

Code 37 doesn't point to one obvious ground the way some codes do — the right one (signage, a procedural error by the council, incorrect notice details, or simply that the contravention didn't happen) depends on what actually happened where you parked, not on the code by itself.
