I think I'm right in saying that outside of London No Motor Vehicle signs are enforced by the Police/Courts. Usually done via a Fixed Penalty Notice; £50 but no points.

In London they're enforced by Councils/TfL with appeals going to a less formal Tribunal. The London Councils have an extensive network of cameras and use them for to issue Penalty Charge Notices by post.

I don't think that's been extended elsewhere in England.

No idea if West Yorks Police use cameras.
