Really off topic now sorry.
“People are unlikely to get caught for speeding here (doing over 30 anyway) as by law I don’t think anything would be enforceable due to lack of clear signage.”
Sorry Mike but this is incorrect.
“Section 82(1)(a) (of the Road Traffic Regulation Act 1984 (RTRA 1984)) defines a restricted road in England and Wales as a road which is provided with “a system of street lighting furnished by means of lamps placed not more than 200 yards apart”. Section 81 specifically makes it an offence for a person to drive a motor vehicle at a speed of more than 30 mph on a restricted road.”
In a built up area with lamposts less than 200 yards apart, the speed limit is 30 mph, signs or no signs. The Police will not accept “no signs” as an excuse for speeding.
