Driving in Ireland from Dublin: what to know before you go

Should you rent a car in Ireland?

A car gives you independence for rural exploration that no coach tour replicates — stopping at a local pub in a Wicklow village, arriving at Glendalough before the day tours roll in, or driving the Ring of Kerry at your own pace. For some itineraries, a car is clearly better.

For Dublin city itself, a car is worse than useless — parking is expensive, the centre has restricted access zones, and taxis and public transport are both faster. If you’re spending time in the city and adding countryside days, the typical approach is to base yourself in Dublin without a car and pick one up from the airport or city for the rural days only.

Car hire in Ireland: the basics

Where to hire: Dublin Airport has all major international rental companies (Avis, Hertz, Enterprise, Europcar, Sixt, Budget) plus several Irish independents. Some operators have desks inside the terminal; others require a short shuttle bus to their lot.

Prices (2026): A small car (Ford Fiesta class) starts around €40–60 per day for 1–3 days, €30–50 per day for a week. Prices spike significantly in July–August. Booking well in advance almost always gets a lower rate than booking on arrival.

Insurance: Check what your credit card covers — some US/EU cards include Collision Damage Waiver (CDW) on car rental abroad. If not covered, factor in CDW at €15–25/day from the rental company. Full coverage (Super CDW with zero excess) costs more but removes stress on narrow country roads.

Automatic vs manual: Most European rental cars are manual. If you need an automatic, book it specifically — availability is limited and costs more. Driving an unfamiliar manual on the left adds to the adjustment.

Age restrictions: Most companies require drivers to be at least 21–23; some charge a young driver supplement for under-25s. Upper age limits (some companies have 70 or 75) are also sometimes applied.

Cross-border Northern Ireland: If you plan to drive into Northern Ireland (Belfast, Giant’s Causeway, Causeway Coast), check that your rental agreement explicitly permits cross-border travel. Most major companies do; some budget operators don’t. This matters for insurance.

Driving on the left

Ireland drives on the left, British-style. For visitors from North America, Australia, Japan and most of Africa and Asia this means a period of adjustment. Key issues:

The first few kilometres are hardest: The instinct to drift left when turning is common. Consciously remind yourself at every junction to keep to the left lane.

The biggest mistake: When pulling out of a T-junction or roundabout, looking left first (when you should look right). Traffic in Ireland comes from the right on a left-hand road. Pause at every junction until the reflex adjusts.

Roundabouts: Traffic on the roundabout has priority over traffic entering. Give way to cars already on the roundabout (coming from your right). Roundabouts are the most common source of wrong-side incidents for non-left-hand-drive visitors.

Passenger seat is on the left: In a standard car, the driver sits on the right. This means the driver needs to reach across further for the gear stick (if manual) and has a different spatial sense of where the car’s left side is.

Allow extra time on your first day of driving and avoid the M50 if possible until you’re comfortable.

Toll roads and the M50

The M50: Dublin’s orbital motorway is a barrier-free, camera-operated toll system. There are no cash booths. Cameras read your number plate; you pay within 24 hours (before midnight the following day) at:

• eflow.ie (online payment — the easiest)
• Spar, Maxol and other convenience stores with eflow payment services

M50 toll cost: €3.10 for most vehicles. If you don’t pay by midnight the following day, the fine is significantly higher. Rental cars often add an administrative fee on top. Most car hire companies offer to handle tolls for you automatically (for a daily fee of €3–5 regardless of whether you use the M50) — worth taking to avoid the hassle.

Other tolls: Some major routes have toll plazas:

• M1 (Dublin to Belfast): Several plazas, €1.50–€2 each, cash or card
• M7/M8 (south): Pay at plaza
• M4 (west): Some toll points
• Various bridges (especially around Limerick and over the Boyne)

Carry a mix of coins and small notes for traditional toll plazas on rural routes.

Road types in Ireland

Motorways (M-roads): Dual carriageway, 120km/h speed limit, modern and well-maintained. M1 (to Belfast), M7/M8 (Cork), M4/M6 (Galway), M9 (Kilkenny/Waterford) are the main ones from Dublin.

National primary roads (N-roads): 100km/h speed limit on rural single carriageway; 100km/h on dual carriageway. Good quality on main routes.

Regional and local roads (R-roads, L-roads): These can be very narrow, particularly in the west (Connemara, Kerry, west Cork). Two-way roads that barely accommodate one car are common — it’s normal to pull into passing places to let oncoming traffic through. Drive slowly, stay to the left, and don’t rely on GPS for road quality.

Speed limits: 50km/h in towns and cities; 80km/h on most regional roads; 100km/h on national roads; 120km/h on motorways. Speed cameras are increasingly common on national roads.

Specific driving routes from Dublin

Wicklow Mountains and Glendalough: M50 south to N81 or N11, then into Wicklow via Blessington or Enniskerry. Mostly good quality roads but narrow through the mountains. Sally Gap and Glenmacnass are beautiful but single-track in parts. Allow 1–1.5 hours from the city to Glendalough.

Kilkenny: N7 to M9 motorway, then south. Easy motorway driving all the way to Kilkenny city. About 1.5 hours.

Cliffs of Moher: M7 west to Limerick, then N18 north to Ennis, N67 to the coast. A long motorway journey (3+ hours from Dublin), then rural roads for the last section. See Cliffs of Moher day trip.

Ring of Kerry: 3–3.5 hours to Killarney via M7 and N21/N22. The Ring of Kerry itself is driven anticlockwise (the official direction for tourist traffic flow). Full day from Dublin.

Belfast: M1 north through the border zone (no checkpoint) to Belfast. Comfortable motorway driving, about 1.5–2 hours. See Dublin to Belfast transport.

Connemara / Galway: M4/M6 west to Galway (about 2.5 hours). Then N59 through Oughterard to Clifden and the Connemara coast — beautiful but narrower roads. See Connemara guide.

Fuel

Petrol and diesel are widely available on all major routes. Rural stations exist but can have limited hours — fill up in larger towns before heading into Connemara, Kerry or the mountains. Ireland uses the same fuel nozzles as mainland Europe (E10 petrol, diesel, plus electric charging at service stations). Fuel prices are in EUR in the Republic and GBP in Northern Ireland.
