Driving in Ireland: Essential Rules

Ireland is built for the road trip. The Wild Atlantic Way, the Ring of Kerry, and the Causeway Coastal Route all reward drivers who can stop where they like, and a hire car reaches the villages, cliffs, and country pubs that no coach tour covers. The main roads are excellent; the rural network is narrower and slower than it looks on the map. A few rules changed recently and are worth knowing before you set off.

• Side of the road: In Ireland you drive on the left-hand side, the same as the UK, and overtake on the right.
• Speed limits have changed: Under the Road Traffic Act 2024, rural local road limits were cut from 80 km/h to 60 km/h in February 2025, and many town and village centres now default to 30 km/h. If you're working from an older guide or app, the numbers may be out of date — always follow the posted signage, which reflects the current limits.
• Alcohol limit: The legal blood alcohol limit is 0.05%, dropping to 0.02% for learner, novice, and professional drivers. Roadside breath testing is common. If you plan to drive, the safest amount is none.
• Narrow rural roads: Many rural and coastal roads are single-track with passing places, and the posted limit is rarely the speed you'll actually drive — build in extra time rather than chasing the sat-nav estimate. Do not overtake unless you can see the road is clear well ahead, and pull into a passing place for faster or larger vehicles.
• Roundabouts: Give way to traffic already on the roundabout, approaching from your right.
• Mobile phones: Handheld phone use while driving is illegal. Hands-free use is permitted.
• Wildlife and livestock: Sheep, cattle, and other livestock cross rural roads without warning, particularly in the west — slow down through farming areas, especially around blind bends.
• Seatbelts: Mandatory for the driver and all passengers.

Ireland charges tolls rather than a vignette — you pay per road, not for network access. Eleven toll points cover the Republic, including the M1 near Drogheda, the M4 near Kinnegad, the M7/M8 near Portlaoise, the N25 Waterford bypass, the Limerick Tunnel, and the Dublin Port Tunnel, where charges rise sharply at peak commuter times. Most of these are staffed plazas — pay by cash or card on the spot. The exception is the M50 around Dublin, which is barrier-free: overhead cameras photograph your number plate as you pass, and the toll must be paid online at eflow.ie, via the app, or at a Payzone outlet by 8pm the following day, or it escalates to a fine. Rental cars rarely include toll cover by default, and an unpaid toll is typically billed to your card after your trip with a supplier administration fee added — check your supplier's toll arrangement at collection, and pay any M50 crossing promptly if you drive it.

Ireland Car Hire Insurance & Border Rules

Every car hire listed on eCarBookers includes the supplier's standard collision damage waiver (CDW) in the basic rate. Standard CDW carries an excess — the amount you would be responsible for in the event of damage. Excess amounts vary by supplier and vehicle class, and the exact figure is displayed clearly before you confirm your booking, so there are no surprises at the desk. You confirm your booking online and pay the balance at the rental desk when you collect the car — unlike most booking platforms, eCarBookers does not charge the full rental amount at the time of booking.

If you prefer to drive with no excess at all, fully comprehensive zero-excess cover is available directly from your supplier when you collect the car. The cover comes from the hire company itself, not a third-party insurer — so once added, there is no excess to pay and no reimbursement claim to file. Because your booking confirmation shows the standard excess that applies, you arrive knowing exactly what the cover replaces.

Certain situations fall outside standard CDW cover across the car hire industry. Tyres, glass, underbody damage, lost or damaged keys, and a flat battery caused by driver error — such as leaving the lights on while the vehicle is unattended — are typically not covered and may result in a separate charge if they occur. Check your booking confirmation for the specific cover terms applicable to your hire, as scope can vary by supplier.

Crossing into Northern Ireland is one of the most common reasons to hire a car in Ireland, and the border itself is open with no checkpoint or passport control — the only sign you've crossed is the speed limit changing from km/h to mph and the currency switching from euro to pound sterling. That said, your rental contract and insurance do not automatically extend across the border: most suppliers charge a cross-border fee, commonly in the region of €30–€40, to extend cover into the UK jurisdiction, and this must be arranged with your supplier at the time of booking. Northern Ireland has no toll roads at all, so once you cross, tolls stop being a consideration — but note that Northern Ireland's drink-drive limit is higher than the Republic's, and a conviction there follows you home. Confirm your cross-border plans with your supplier before you book.

Popular Car Hire Locations in Ireland

eCarBookers compares car hire across Ireland's key collection points. Dublin is the main international gateway, with collection at the airport and in the city, while Cork and Shannon serve the south and west — the natural starting points for the Ring of Kerry and the Wild Atlantic Way. Every location follows the same model: book online, see every cost before you confirm, and pay the balance at the desk on collection.
