Traffic Signs

Wherever you go, traffic signs are generally recognisable even if they look a little different. But there are some you won't know, and some may have slightly different meanings.

Here is a guide to signs that you'll most likely encounter on Irish roads. A number of signs will be accompanied by supplementary plate to emphasise meaning, or to indicate distance, direction or exceptions.
