Irish Road Signs Guide
Understanding road signs, markings, and signals in Ireland
Understanding Irish Road Signs
Road signs in Ireland generally follow international standards but have some unique features that visitors should be aware of. Signs appear in both English and Irish (Gaelic) languages, with Irish typically appearing first on signs in Gaeltacht (Irish-speaking) regions.
For international visitors, particularly those not familiar with driving on the left or European road signs, understanding Irish road signs is essential for safe and stress-free driving. This guide will help you recognize and interpret the most common signs you'll encounter on Irish roads.
Important Note
In the Republic of Ireland, distances and speed limits are displayed in kilometers, while in Northern Ireland (part of the UK), they are in miles. Be aware of this difference if your journey takes you across the border.
Irish road signs feature both English and Irish languages

Uniquely Irish Road Signs
Some road signs are unique to Ireland or have special significance for visitors.
Gaeltacht Area
This sign indicates you are entering a Gaeltacht area where Irish is the primary language. In these regions, road signs may appear in Irish only or with Irish displayed more prominently than English.
Key Gaeltacht areas include parts of Counties Donegal, Mayo, Galway, Kerry, Cork, Meath, and Waterford.
Wild Atlantic Way Route Marker
These distinctive blue markers with a white wave symbol indicate you are on the Wild Atlantic Way scenic driving route. They appear frequently along the 2,500km coastal route from Donegal to Cork.
Similar markers exist for other tourist driving routes like Ireland's Ancient East (yellow/orange symbols) and Ireland's Hidden Heartlands (green symbols).
"Uneven Road" Sign
While similar to international versions, Ireland's uneven road sign is notorious among visitors for its dramatic depiction of a car seemingly launching into the air. Take this sign seriously on rural roads, as it often indicates severe dips or humps that can be dangerous at speed.
Animals Crossing
Ireland has various animal crossing signs depending on the region. You might see signs for sheep, cattle, deer, or even ducks. These are not merely decorative - free-roaming animals are common on rural roads, particularly in mountainous areas.
Tips for International Visitors
Language on Signs
Road signs in Ireland typically display text in both English and Irish (Gaelic). In Gaeltacht (Irish-speaking) regions, signs may be in Irish only or with Irish more prominent.
Some common Irish terms you might see on signs:
- Slí Amach / Exit - Exit
- Géill Slí / Yield - Give way/Yield
- Stad / Stop - Stop
- Mall / Slow - Slow
- Baile / Town - Town
- Lár an Bhaile / Town Centre - Town center
Speed Limits
In the Republic of Ireland, all speed limits are in kilometers per hour (km/h).
Standard speed limits (unless otherwise signed):
- Motorways: 120 km/h (75 mph)
- National Roads: 100 km/h (62 mph)
- Regional and Local Roads: 80 km/h (50 mph)
- Built-up Areas: 50 km/h (31 mph)
- Special Limits: 30 km/h (19 mph) in some areas
Northern Ireland: If crossing into Northern Ireland, be aware that speed limits change to miles per hour (mph).
Road Numbering System
Ireland uses a letter-number system to classify roads:
- M Roads (Blue signs): Motorways, highest standard roads (e.g., M50, M1)
- N Roads (Green signs): National roads connecting major cities/towns
- N1-N50: National Primary Roads
- N51-N99: National Secondary Roads
- R Roads (White signs): Regional roads connecting smaller towns
- L Roads: Local roads (often unnumbered on signs)
Road numbers are often used for navigation and appear on signposts in a colored box corresponding to the road type.
Roundabouts
Roundabouts are extremely common in Ireland. Key points to remember:
- Traffic moves counterclockwise around roundabouts
- Always give way to traffic already on the roundabout (coming from your right)
- Signal left when exiting the roundabout
- For straight ahead: stay in left lane (generally)
- For right or full circle: approach in right lane, signal right
Many roundabouts have directional signs on the approach showing the correct lane for each exit. Follow these carefully as lane discipline is important.
Rural Signs & Hazards
On rural roads, pay special attention to:
- Hidden Dip signs: Can indicate severe undulations in the road
- Animal crossing signs: Particularly common in rural areas
- Narrow bridge signs: Often indicate single-lane bridges where you must yield to oncoming traffic
- "Road Liable to Flooding" signs: Common near coasts and rivers
Rural roads may have few or inconsistent signs. Drive cautiously and be prepared for unmarked hazards, especially on local roads.
Toll Roads
Toll roads are indicated by specific signs:
- Standard Toll: Signs indicate payment at toll booths
- M50 Barrier-Free Toll: Special signs with cameras symbol remind you to pay by 8 PM the next day
- Dublin Port Tunnel: Variable toll rates depending on time of day and vehicle type
