The Traffic Signs General (Amendment) Directions 1999
These Directions amend the Traffic Signs General Directions 1994 so as to insert a new direction 14A limiting the circumstances in which the traffic sign shown in diagram 674 (entrance to 20 miles per hour speed limit zone) may be placed by a traffic authority. The sign may only be placed on a road (other than a cul-de-sac less than 80 metres long) if no point on any road, to which the speed limit indicated by the sign applies, is situated more than 100 metres from a “traffic calming feature” as defined by direction 14A(2).
