Example of a third class Road on a map
In this example Third Class Roads run from Roundwood in County Wicklow towards Lough Dan.
These roads are very small roads.
They often will not have a central dividing line or side of the road markings. Extra care is therefore required when using Third Class roads.
Third Class Roads tend to be in not very densely populated areas such as these roads from Roundwood towards Lough Dan.
