does ireland drive on the left side of the road
Left- and right-hand traffic Many of the countries with LHT are former British colonies in the Caribbean, Southern Africa, Southeast Asia, South Asia, Australia, and New Zealand. Japan, Thailand, Nepal, Bhutan, Mozambique, Suriname, East Timor, and Indonesia are among those LHT countries outside the former British Empire. In Europe, only four countries still drive on the left: the United Kingdom, Ireland, Malta, and Cyprus, all of which are on islands that have no direct road connections with countries driving on the right.
Irish Sea Ferry connections from Wales to Ireland across the Irish Sea include Fishguard Harbour and Pembroke to Rosslare, Holyhead to Dún Laoghaire and Holyhead to Dublin. From Scotland, Cairnryan connects with both Belfast and Larne. There is also a connection between Liverpool and Belfast via the Isle of Man or direct from Birkenhead. The world's largest car ferry, Ulysses, is operated by Irish Ferries on the Dublin Port–Holyhead route; Stena Line also operates between Britain and Ireland.
