Traffic Signs

The use of Irish on the country's traffic signs is the most visible illustration of the state's policy regarding our official languages, Irish and English. The road authorities are obliged to adhere to the obligations imposed on them with regard to the use of those languages on traffic signs under the Traffic Signs Manual. Those obligations are explained in the information leaflet entitled Use of Irish on Traffic Signs which can be downloaded here.

The Irish language provisions for traffic signs under the Traffic Signs Manual are provisions of an enactment relating to the status or use of Irish. This means that An Coimisinéir Teanga has statutory authority to investigate complaints regarding problems with the use of Irish or lack of Irish on traffic signs.

If it appears to you that traffic signs have been erected by the road authorities that are not in accordance with the statutory provisions, you may wish to complain to the Office of An Coimisinéir Teanga on the complaint form.
