No restriction we know of
Rhiwiau is recorded as a Unclassified County Road. We haven't found a Traffic Regulation Order or seasonal closure on it, but that doesn't guarantee there isn't one.
UCRs are on the council’s list of streets, which doesn’t confirm motor vehicle rights the way a BOAT designation does. Worth checking locally.
