Tips for Driving in Ireland

Ireland is one of the world's most popular destinations with numerous attractions located in the beautiful countryside. Get familiar with local rules, signs, and types of rental cars available before you embark on your journey.


Unique Road Signs

Road signs typically show distances and speed limits, as well as important information. Road signs and place names are displayed in both Irish (Gaelic) and English. In Gaeltacht areas (where Irish is the primary language) only Irish is used. It is important to know a few Gaelic terms while traveling in Ireland. Learn more about Ireland road signs here.

Fuel Your Adventure 

Opposite from what is common in the U.S., green handle pumps are unleaded petrol (gas), and black handles are diesel. The petrol cap on your vehicle will indicate whether it takes petrol or diesel.

Park Smart
