Driving in Ireland: What to Confirm Before You Travel
We have not completed source-backed research for Ireland, so this page does not state whether an International Driving Permit is required. Ireland drives on the left. Ireland is party to the 1949 Geneva Convention. Confirm current requirements with the relevant national authority and your rental provider before you drive.
Which convention applies
Ireland is party to the 1949 Geneva Convention. The convention determines which IDP format has a legal basis here, which is why two IDPs that look similar are not always interchangeable.

Is a digital IDP accepted in Ireland?
Not confirmed. No published Irish national policy confirming acceptance of digital-only driving documents was found. Carry the original licence.
This is the least documented question in this category. Most national authorities have not published a position on digital-only driving documents, and rental companies set their own rules. Carry a printed document and treat any digital copy as a convenience, not a substitute. See our explanation of what an IDP is for more.
What to carry
- Original valid national driving licence
- Translation or IDP where the licence is not in English or Irish
- Passport or photographic ID
- Rental agreement and insurance documents
Your original national driving licence is the document that grants driving privileges. A translation-support document is presented alongside it and never replaces it.
Rental desks and roadside checks in Ireland
At the rental desk. Irish rental firms apply their own age limits and frequently exclude certain vehicle classes for younger drivers. Damage excesses tend to be high, and many roads outside the motorway network are narrow with stone walls or hedgerows close to the carriageway — check what the collision waiver actually covers.
In a roadside check. Ireland drives on the left, which is the single most common source of difficulty for visitors arriving from mainland Europe or the Americas. The alcohol limit is tiered at 50 mg per 100 ml for most drivers and 20 mg for learner, novice and professional drivers. Speed limits are posted in km/h, unlike neighbouring Northern Ireland which uses mph.

Why this page does not state a requirement
We publish a requirement only when we can point to an official source and record the date we checked it. That research is not yet complete for Ireland, so this page deliberately does not tell you whether an IDP is required.
For transparency: an internal dataset records this destination as "recommended", which we have not yet confirmed against an official source; and a motorway limit of 120 km/h is recorded but unconfirmed.
Confirm with the national road authority or embassy for Ireland, and separately with your rental provider, whose contractual rules can be stricter than the law.

Ireland driving document questions

Generally no. Visitors can usually drive on a full valid licence from their home country for up to 12 months. An IDP is most useful where your licence is not written in English or Irish.
Which side of the road does Ireland drive on?
The left. Speed limits are posted in kilometres per hour, unlike Northern Ireland across the border which also drives on the left but posts limits in miles per hour.
How long can I drive in Ireland on a foreign licence?
Generally up to 12 months on a full valid licence from your home country. Becoming resident brings separate exchange or testing requirements into play.
What is the drink-drive limit in Ireland?
50 mg per 100 ml of blood for most drivers, reduced to 20 mg for learner, novice and professional drivers.
