Hiring a Car in Ireland: What Nobody Tells You Before You Land

Ask a room full of people who’ve driven Ireland what caught them out, and almost nobody says the narrow roads. They say the insurance desk.

Hiring a car is the right call for most Ireland trips — the best of this island is on roads no coach goes down. But the rental process here has a few genuine traps, and one of them costs people hundreds of euro at the counter while they’re jet-lagged and holding a queue up behind them.

The one that catches nearly everyone

Most credit-card rental insurance does not cover Ireland.

Ireland is one of a very small number of countries that card issuers routinely exclude from their collision damage waiver benefit. Travellers who’ve relied on that card for a decade of rentals elsewhere arrive in Dublin, decline the desk insurance, and discover the exclusion at the worst possible moment.

Two things to do before you fly:

• Ring your card issuer and ask specifically about the Republic of Ireland. Not “Europe” — Ireland by name. Get the answer in writing if you can.
• If your card does cover it, ask them for a letter of coverage. Irish rental desks frequently ask to see proof, and a printed letter ends the conversation.

If you’re not covered, budget for the rental company’s own cover. It is expensive — often approaching the cost of the car itself — but the alternative is an excess that can run into the thousands.

Take the excess reduction. Really.

Standard Irish hire agreements carry a high excess, and the roads here are unusually good at producing exactly the sort of damage it applies to. Stone walls sit right at the edge of the tarmac. Hedgerows hide the width of the lane. Wing mirrors and alloys take the worst of it.

Most people who’ve driven Ireland twice buy the excess reduction the second time.

Book an automatic early, or learn to love the clutch

Manual is the default here. Automatics exist, but they’re a minority of the fleet, they cost more, and in July and August they sell out. If you need one — and if you’ve never driven a manual on the left, you probably do — book months ahead, not weeks.

And book the smallest car you can live with. Every inch you didn’t pay for is an inch you don’t have to squeeze past a tractor on a lane with walls on both sides.

The border changes the speed limits

This one surprises people. The Republic posts speed limits in kilometres per hour. Northern Ireland posts them in miles per hour. There’s no checkpoint to tell you you’ve crossed — the road just carries on — and a sign reading 60 means two very different things depending on which side of an invisible line you’re standing.

Your hire car’s speedometer will show both. Learn which ring you’re reading before you set off.

Tolls, and the one that bills you later

Most Irish motorway tolls are ordinary booths — you pay as you pass. The exception is the M50 around Dublin, which has no barriers at all. Cameras read your plate and you’re expected to pay online afterwards, by 8pm the following day.

Miss it and the fine escalates, and it will find you through the hire company weeks later with an administration fee attached. Ask at the desk how your rental handles the M50 — some include a tag, some don’t. If yours doesn’t, pay it the same evening from your phone.

Fuel: read the cap, not the pump

Diesel is common here in a way it isn’t everywhere, and misfuelling a hire car is an expensive, entirely avoidable afternoon. Check the filler cap before your first fill, and again if you swap cars.

A short checklist

• Confirm in writing whether your card covers the Republic of Ireland
• Book an automatic early if you need one
• Choose the smallest car that fits your luggage
• Take the excess reduction unless you’re genuinely covered elsewhere
• Photograph every panel, wheel and mirror before you leave the lot
• Ask how the M50 toll is handled
• Check the fuel type at the cap
• Collect the car outside the city if you can — nobody’s first hour on the left should be in Dublin traffic

None of this should put you off. Driving Ireland is the entire point of coming here — the Beara road, Slea Head, the Antrim coast. Just sort the paperwork before you’re standing at a desk at seven in the morning with a queue behind you.
