Road Signs in Ireland

Road signs in Ireland mostly differ from the traffic signs used elsewhere in Europe. Directional signage is similar to that of the United Kingdom, but is bilingual. Distances are in kilometres. Apart from directional signage, the basic prohibitory signs such as "no left turn" and "no right turn" are among the few standard signs used in Ireland. The most widespread signage, hazard or warning signs, employs the yellow diamond layout used in the United States, Canada, Australia and elsewhere, but nowhere else in Europe. The actual symbols used on these warning signs, however, often bear a closer resemblance to those used in the rest of Europe than to those seen in the US. On 20 January 2005, Ireland fully adopted metric speed limits. Around 35,000 existing signs were replaced and a further 23,000 new signs erected bearing the speed limit in kilometres per hour. To avoid confusion with the old signs, each speed limit sign now has "km/h" beneath the numerals.

Irish signs depict classical silhouetted persons.
