What should you do?
Use the diagram to choose the correct lane and exit before reaching the roundabout, and signal as required.
How to recognise it
A white rectangle with black text showing a roundabout layout, a blue M50 Dublin panel and an aircraft symbol for Dublin Airport.
Common confusion
Colour-coded panels show the type of road you will join; the blue panel here means that exit leads to the motorway.
