5.2.1. The sign to diagram 617 (S3‑2‑11, see Figure 5‑5) prohibits all vehicles including ridden pedal cycles and horse‑drawn vehicles. Normally it is used either for Play Streets (where vehicles are admitted only for access) or for shopping streets closed to vehicles and PROHIBITION OF TRAFFIC 46 where ridden pedal cycles would be a hazard to pedestrians. The sign must always be used in combination with a supplementary plate (Schedule 3 General Direction 3). The signs are used where the prohibition applies to the whole of the road in both directions; they should not be used to indicate one‑way or tidal‑flow traffic systems. The majority of vehicle‑free shopping streets are likely to be pedestrian zones, where a sign to diagram 618.3B (S8‑2‑1) should be used in place of diagram 617 (see section 6).
5.2.2. A Play Street is indicated by a plate legend specified in S3‑3‑12 (“Play Street except for access”) or S3‑3‑13 (“Play Street” and a time period and “except for access”). The sign to diagram 617 may be used with the road marking to diagram 1046.1 (“PLAY STREET”) (S9‑6‑18, see Figure 5‑6). The road marking legend may be laid in a single line or in two lines depending on the carriageway or lane width available. Vehicular access to premises on a play street must be maintained at all times as the Regulations do not permit the words “except for access” to be omitted from the supplementary plate or for access to apply during a shorter period than the operational times of the play street.
