Having a bit of hassle with grandchildren learning to drive, there is a road sign on bad bends near here which is circular, black border and 30 on white in the centre. They insist that it is a 30 mph limit however I say it is an advisory sign saying recommended maximum speed is 30mph. (There used to be Rectangular signs there saying Max Recommended Speed 30 but these replaced them.
I cannot find anything on google about this type of sign anyone confirm please.
