Driving in Ireland: licences, car rental and road rules
Rent a car only for the west and south-west — Connemara, Kerry, Donegal, the Burren — where buses are thin. Expect €40–90 a day plus fuel at about €1.75–1.90 a litre, and budget for excess cover because many card policies exclude Ireland. Skip the car in Dublin and Belfast.

Summary: who should drive, when and what it costs
Use this to decide before you book flights. If your trip is Dublin plus one west-coast base, a car is optional; if it is Connemara, Kerry or Donegal, it is close to essential.
| Traveller | Rent a car? | Why |
|---|---|---|
| Dublin-only city break | No | Traffic, parking costs and good bus, Luas and DART coverage |
| Dublin plus Galway or Cork by train | No | Rail and express buses cover the main routes |
| West coast: Connemara, Mayo, Donegal | Yes | Few trains, rural buses run a few times a day or not on Sundays |
| South-west: Kerry, Dingle, Beara | Yes | The Ring of Kerry and peninsula roads are impractical without one |
| Family with young children | Often yes | Car seats, luggage and flexible stops; see ireland with kids |
| Nervous first-time left-side driver | Maybe not | Start with a day tour, or collect the car outside the city |
| Long stay or working holiday | Depends | Check licence exchange rules; see Ireland long-stay and working visas |
Step by step: booking, collecting and driving
Book the car before the ferry or flight if you travel in July or August. Automatics are limited, and one-way rentals between Dublin and Shannon or Cork carry a drop fee. Compare the total, not the headline rate: insurance, an extra driver and a young-driver surcharge all land at the desk.
Collect at the airport if you land at Shannon or Cork, where the roads out are easy. At Dublin Airport, consider taking a bus into the city and collecting a car on a later day, which avoids city traffic and overnight parking. Bring your licence, passport and a credit card in the main driver's name; debit cards are often refused for the deposit.
Decide on insurance before you queue. Many US and credit-card policies exclude Ireland, so the desk will offer collision damage waiver or excess cover, typically €15–30 a day. A standalone excess policy bought at home is often cheaper, but check it covers Ireland.
On the road: keep left, and remember the driver sits on the right, so your instinct at a junction is wrong for the first day. Take roundabouts clockwise. On single-track roads, use the marked passing bays. Give way to traffic already on the roundabout, and expect tractors, cyclists and sheep on regional roads.
Plan driving times generously. Galway to Dingle is about 4 hours without stops, and the Ring of Kerry loop is 4–5 hours of driving alone. Two hours of map distance can be half a day on the west coast.
| Cost item | 2026 estimate | Notes |
|---|---|---|
| Compact car, low season | €40–60 a day | Booked ahead, manual |
| Compact car, July–August | €70–90 a day | Automatics cost more |
| Excess cover at the desk | €15–30 a day | Check your own policy first |
| Fuel | €1.75–1.90 a litre | Petrol and diesel; many rentals are diesel |
| Tolls | €2–3.50 per plaza | M50 billed by camera — check |
| Parking, town centre | €2–4 an hour | Hotel parking often extra — check |
Notes and traps
Rural roads are narrow, hedged and often without a hard shoulder. Do not treat an 80 km/h regional limit as a target; locals drive them fast because they know every bend.
Fuel stations thin out in the west and north-west. Fill up when you see one, especially on a Sunday evening or a bank holiday.
Winter daylight is short: sunset can be before 16:30 in December, which rules out long scenic drives after lunch. Summer gives daylight until about 22:00, which is why May to September is the driving season.
Watch for the M50 barrier-free toll near Dublin and for rental companies billing tolls back to you with an admin fee. Ask how they handle it at collection.
If you drink, do not drive. Limits are low and enforcement is routine, including morning checks after a late night.

Questions people ask
What should I know about driving and car rental in Ireland?
You drive on the left with the wheel on the right. Rent a car for the west and south-west, not for Dublin. Budget €40–90 a day plus fuel, and expect to buy excess cover because many card policies exclude Ireland.
How much does it cost?
A compact car is about €40–60 a day in low season and €70–90 in July and August, plus €15–30 a day for excess cover if you need it. Fuel runs about €1.75–1.90 a litre. Tolls are €2–3.50 per plaza.
When should I plan for it?
Book two to three months ahead for June to September, and earlier if you need an automatic or a one-way drop. May, June and September give the best mix of daylight, weather and quieter roads.
Can I use my US or UK licence?
Yes for a short visit. Carry your licence and passport, and check with the rental company whether an international driving permit is requested. Rules differ for residents and long stays.
Do I need a car in Dublin?
No. Dublin Bus, the Luas and the DART cover the city and suburbs, and parking is expensive. Collect a car when you leave the city, or at Shannon or Cork airport.
Is driving in Ireland hard for a first-timer?
The left-side habit takes a day to settle. Start on quiet roads, avoid Dublin city centre, and take roundabouts slowly. Single-track roads in the west need care but are manageable.
