What should you do?
Confirm your direction and take the junction carefully, as regional roads can be narrower than national roads.
How to recognise it
White pointed signs with black text such as B. Átha Luain / ATHLONE R363 and a distance in km.
Common confusion
The R prefix and the white background mark it as a regional route, not a national one.
