Aer Lingus and Ryanair provide services from Dublin, Cork and Shannon to numerous destinations in Portugal.
Ensure that you hold a full and valid Irish or international licence. Driving in Portugal is on the right. You should familiarise yourself with the Portuguese rules of the road. The speed-limit is generally 50 km/h in built up areas, 90 km/h on main roads and 120 km/h on motorways. The speed limit on dual carriageways is 100 km/h. Fixed cameras and mobile police patrols carry out speed checks. If found to be speeding, you will be fined and your licence may be confiscated immediately by the police.
Most motorways are subject to tolls. Ensure that you have enough money with you to pay tolls before setting out on your journey, as Irish credit cards are not always accepted by the machines in toll booths.
There are severe penalties in Portugal for driving under the influence of drugs and alcohol. The alcohol limit is 0.5 g/l. If you are caught with alcohol in your system while driving it can lead to heavy on-the-spot fines, confiscation of your licence and/or imprisonment.
