Driving in Ireland.
In Ireland north and south we drive on the left hand side of the road, all cars are right-hand drive. Manual transmission is standard although automatics are available. An EU driving licence is valid in Ireland. If you're from outside the EU its a good idea to obtain an International Driving Permit (IDP), usually available from your local motoring organization or motor taxation department.
It is interesting to note that driving on the left originates from AD 120 when traffic on the new Roman roads built in Britain was ordered to drive on the left.
The road system in Ireland is generally quite good, most large city's are connected by motorways or dual carriageways. Some traffic congestion can be expected in and around city's and large towns, particularly during the morning and evening rush hours, try to avoid these if possible. Southern Ireland operate a toll system on their motorways always carry a few euros, the toll booths will accept Sterling (English money) but will treat it £ for € so you will loose out.
Republic of Ireland:
120 km/h motorways (75 MPH)
