Speed limit appears to be 40mph at the north end of this segment of road (at roundabout). I'll fix that but haven't surveyed south of the roundabout

40mph limit now extends east from roundabout, but haven't checked how far

I have a saved bit of dashcam footage from 23/6/22 showing the sign on the open gate of the car park:
ORD STATTER
CAR PARK
OPEN 8am CLOSED 5pm
(No Dogs)

and I'm 90% sure it was free (but my memory may be failing me). Not a local to chacewater though, so perhaps sign is out of date.

There's a new 20mph limit around here, but I don't know how far west into/through the village it goes

Unsuitable for HGVs, but not sure how far up Silver Hill it applies (no further signs visible from Greenwith Rd).
