4. Zone

A traffic zone is an area in which a traffic rule applies throughout all included roads or road sections. The rule normally begins at a zone-entry sign and remains applicable until the corresponding end-of-zone sign is passed.

Zones may regulate speed, parking, access, vehicle categories, emissions or other traffic behaviour. The signs used, the roads covered and the effect of intersections or local exceptions depend on local traffic law.

How do people refer to traffic zones in Ireland?

A Slow Zone is labelled Crios Mall in Irish. The entrance includes a numerical speed-limit sign, commonly 30 km/h, alongside the Slow Zone information.

Where does a zone rule apply in Ireland?

Apply the signed limit on the roads covered by the local speed-limit arrangement. Read numerical signs at the entrance and on connecting roads; the decorative or warning part of a Slow Zone panel is not a separate permission to choose your speed.

How do you know when a traffic zone ends in Ireland?

Follow signs showing the applicable limit as you leave. Do not assume that leaving a housing estate automatically restores a particular speed, because adjoining roads may also have a lower local limit.
