Last September, I introduced a new multi-lingual road traffic sign to warn drivers of the requirement to drive on the left-hand side of the road. Details of the sign are set out in a comprehensive new traffic signs manual which I published last December and a copy of which is available in the Oireachtas Library. The erection of the new sign at appropriate locations is a matter for the individual road authorities.
The National Safety Council's information leaflet for tourists provides information on rules of the road, in three languages, including clear advice that all traffic must drive on the left.
