RUS 013 No Left Turn
The No Left Turn Sign, RUS 013, is used to indicate a prohibited left turn.
The sign shall be located on the left-hand side of the road approaching the prohibited turn. Where the sign is likely to be obscured or is located on a one-way road, it should be duplicated on the right-hand side. It should also be duplicated on the central reserve of a dual carriageway.
In cases where a turning prohibition indicated by the RUS 013 sign applies only to certain vehicle types, or during specific periods of the day, a Supplementary Plate P 050, Exceptions, or P 051, Period of Operation, shall be used to define the conditions that apply.
