Good to know: Ireland Driving Etiquette: 

Every country has its own etiquette or unwritten rules, and Ireland is no exception. Here are a few handy tips that will be appreciated by the locals and will help you avoid misunderstandings.

• Flashing headlights: used quite often, also to say thank you or to indicate another driver to go ahead – especially at passing places on narrow roads. 
• The raised hand: A small hand or finger raised from the steering wheel is a simple way to say thanks when someone lets you pass. Use it – you’ll feel like a local in no time.
• The locals know the roads and will usually drive faster than visitors. They are often going to work. Don’t feel pressured to match their speed and let them pass where safe to do so.
• On the single track lanes, always note where the passing places are – you may need to reverse back to one. 

Good to know before you go 

Road signs use international symbols, and speed limits are in kilometres per hour. You might also see signs in Irish (Gaelic), especially in some of the more rural counties like Connemara, Donegal or Mayo or but don’t worry, the directions are usually clear.

If you are not used to them, roundabouts may feel a little puzzling at first. With these simple tips, you’ll soon be navigating them like a local.

• Give way to traffic coming from the right.
• Enter by turning left and keep moving clockwise.
• Signal your exit just like a regular turn.
  

Parking in towns can be tricky. Look out for Pay and Display machines – you usually pay at a nearby kiosk, machine  or via a mobile app and will need to display your ticket on the dashboard. Don’t park on yellow lines, driveways, and footpaths (sidewalks), or your wallet might have a fine when you return!

Fuel (petrol/diesel) is sold on litres 

Top tips

Don’t forget the mantra:  – Keep left and look right when pulling out into traffic.

When you are on the motorway (highway)  the slow lane is the left lane, passing happens in the right lane

what to expect: irish roads 

Unlike the modern highways, Ireland’s rural lanes wind between weathered stone walls with sheep often outnumbering cars.

types of roads

• Motorways (M roads): Connect major cities with multi-lane efficiency. Some motorways will have tolls. 
• National roads (N roads): Key routes linking major regions and towns. They can be dual or single carriage way.
• Regional roads (R roads): Often photogenic , these connect smaller towns and villages. Can be narrow and winding.
•  Local roads (L roads) Link small towns and villages. Delightfully scenic but often narrow and single track with passing places. Take your time and pull over for oncoming cars when needed. They can vary widely in condition.

tolls you’ll encounter

Several Irish roads require toll payments. Most toll plazas accept both cash and card payments.

The M50 motorway around Dublin uses barrier-free tolling. You can pay before 8 pm the following day online or at Payzone outlets. Other motorways (M1, M3, M4, M7, M8) have traditional toll plazas where you stop and pay.

things to consider on irish roads

Livestock: Sheep and cattle cross roads in rural areas. If you meet a farmer moving livestock, stop and wait. Rural Ireland operates on a different clock. Embrace it.

Tractors and farm equipment: Agricultural vehicles move slowly on narrow roads. Overtake only when you have clear visibility ahead. of you

Narrow roads: Many country roads barely fit two cars. The driver closest to a passing place typically reverses to the passing place. A friendly wave acknowledges the courtesy.Weather: Irish weather changes quickly. Morning sunshine gives way to afternoon rain. Mist rolls off mountains and reduces visibility. Drive to conditions, not posted limits.

must-see routes you can’t miss

Here are just a few of our favourite drives in Ireland:

The Wild Atlantic Way is one of the world’s great coastal drives, stretching along Ireland’s western edge from Malin Head in Donegal in the north to the pretty coastal town of Kinsale in County Cork on the south coast. It winds its way through ever-changing seascapes, rugged headlands with towering cliffs, remote beaches and lively coastal towns. It offers a front-row seat to the raw beauty of the Atlantic coast.

Among its many highlights, a few sections stand out as our favourites are:…..

Ring of Kerry: This 179-kilometre loop circles the Iveragh Peninsula. Stop at Ladies View where Victorian royalty once paused to admire Killarney’s lakes.

The 22 mile Slea head Drive starting and finishing in the buzzing coastal town of Dingle,  is  possibly one of Ireland’s most iconic coastal routes. Famed for its dramatic views of the Atlantic, rugged cliffs, and timeless villages. The thin sinew of road clings to the cliff edge, winding past stone walls, ancient forts, and hidden coves, making every turn a breathtaking experience. Top tip – Must be driven clockwise!

A drive around the north western outpost Achill Island of County Mayo takes some beating. The scenery, beaches and villages  are just breath-taking. Highlights include the windswept sands of Keel Beach, the rugged cliffs of Slievemore, the picturesque Doo Lough Valley and the striking desert-like landscape at Minaun Cliffs.

Causeway Coastal Route: Journey along the Coastal Causeway Route: that links Belfast with the friendly city of Derry and discover some of the most beautiful and varied scenery in Northern Ireland. This road was not built until the mid 1800’s, snaking its way along the narrow strip of coastline between sea and the cliffs, it is now one of Europe’s top road journeys. Visit the whitewashed fishing village of Cushenden for excellent seafood, seek out Game of Thrones’ spectacular settings and don’t miss the breathtaking panoramic cliff top views from the Torr Head.

frequently asked questions

Do I need an International Driving Permit? It depends on where your license was issued. If it’s from the EU, UK, US, Canada, Australia, or New Zealand, you don’t need an IDP. If your license isn’t in English or from one of these countries, you’ll need an IDP alongside your original license.

Which side of the road does Ireland drive on? Traffic travels on the left. You’ll sit on the right side of the vehicle and yield to traffic from the right at roundabouts.

Are Irish roads difficult to navigate? Main roads are straightforward. Rural lanes require attention due to narrow widths. Take your time, especially when adjusting to driving on the left side. Within a day or two, it becomes natural.

Do I need a car in Dublin? No. It is best not to have a car in Dublin. It is a compact and very walkable city with almost all major tourist sights near to the centre. Taxis, Uber and public transport options are widely available.
