What should you do?
Reduce your speed to the limit shown and expect speed ramps, chicanes and pedestrians.
How to recognise it
A grey panel with the place name Cluain Dolcáin / CLONDALKIN, a red-ringed 30 km/h sign and Ceansú Tráchta / TRAFFIC CALMING.
Common confusion
The 30 km/h on this panel is a speed limit, not an advisory speed.
