Speed limits in Ireland: what the unsigned road means now
Every Irish limit in km/h and mph, the February 2025 change, and the phase that has not started yet.
Most Irish country roads have no speed limit sign on them. Since February 2025 the answer to what that means has changed, and it changed on about 82,000 kilometers of road.
| Where you are | Limit | In mph |
|---|---|---|
| Motorway | 120 km/h | 75 |
| National primary road, the green N-roads | 100 km/h | 62 |
| National secondary road, also green N-roads | 100 km/h | 62 |
| Regional road, the R-roads | 80 km/h | 50 |
| Local rural road, usually unsigned | 60 km/h | 37 |
| Built-up area | 50 km/h | 31 |
What changed, and why it matters more to you than to a local
On 7 February 2025, the default limit on Ireland's local rural roads dropped from 80 km/h to 60. That is about 82,000 kilometers, and it is most of the rural network.
It matters disproportionately to a visitor because the local road is the one you are on. The scenic route to the Cliffs of Moher, the road to the cottage, the shortcut your map app likes: those are local roads. The motorway is the part you spend the least time on.
If you learned Irish limits from a guide written before February 2025, you are carrying an 80 in your head for roads that are now 60.
How to tell which road you are on
Ireland makes this easier than most countries, because the road classification is written on the sign and color-coded.
Blue signs are motorways. M-roads. 120.
Green signs are national roads. N-roads, both primary and secondary. 100.
White signs with an R number are regional roads. 80.
No number, no sign, just a road: that is a local road, and it is 60.
The practical version is one sentence: no sign on a country road means 60, which is 37 mph.
The part where we tell you this page will go out of date
There is a second phase, it is already law, and it has not started.
Under the Road Traffic Act 2024, national secondary roads are due to drop from 100 km/h to 80, and built-up areas from 50 to 30. Neither has commenced, and no date has been confirmed.
We are telling you that rather than quietly picking a date, because the honest state of Irish speed limits right now is "one phase done, one phase coming, timing unannounced." Check before you travel. This page will be updated when it moves.
What it costs if you get it wrong
Speeding in Ireland carries a fixed charge of 160 euro and 3 penalty points.
Pay it inside 28 days and that is the whole of it. Pay between days 29 and 56 and it rises to 240 euro. After day 56 no payment is accepted and a court summons follows, where a conviction can reach 1,000 euro and 5 penalty points.
Ireland's penalty points system is separate from the fine and it is the part people underestimate: twelve points inside three years is a six-month disqualification.
The number is not the speed
A 60 km/h limit on an Irish boreen is a legal maximum, not a recommendation.
Many local roads are one car wide with grass up the middle, a stone wall on one side and a hedge on the other, and a blind bend every two hundred meters. The limit says 60. The road says considerably less than that, and so does the tractor around the corner.
This is worth saying plainly because the number dropping from 80 to 60 can read as permission to do 60. It is not. It is a ceiling that was lowered because the old ceiling was getting people killed.
The part that has nothing to do with speed
You will be driving on the left, sitting on the right, with mirrors in unfamiliar places, on a road narrower than anything at home, and now you are also classifying road signs by color to work out what the limit is.
That is one more thing on a working memory that is already full on day one.
The colors are easy to learn and you have just learned them. The part that takes practice is doing it while the keeping-left is still costing you effort, which on most people's first trip is about three days.
What to do before you land
Learn the table. It takes a minute.
Then spend your practice on the thing that does not come from reading: holding the left side while your attention is somewhere else. LeftLane runs in your browser on a computer, tablet, or phone held sideways, and the first 10 scenarios are free forever, with no signup and no card. Twenty more sit behind a one-time pass if you want them.
Our longer guide to driving in Ireland for the first time covers rental pickup, roundabouts and the narrow-road etiquette that the speed limit does not describe.
No sign on a country road means 60.
Common questions
What is the speed limit on Irish country roads?
60 km/h, which is about 37 mph, on local rural roads with no speed limit sign. This changed from 80 km/h on 7 February 2025 and affects around 82,000 kilometers of road.
What is the motorway speed limit in Ireland?
120 km/h, which is about 75 mph, on blue-signed M-roads.
How do I know what road I am on in Ireland?
By sign color and letter. Blue M is motorway at 120. Green N is a national road at 100. White R is a regional road at 80. No number and no sign means a local road at 60.
Are Irish speed limits changing again?
Yes, and the date is not confirmed. Under the Road Traffic Act 2024 national secondary roads are due to drop from 100 to 80 km/h and built-up areas from 50 to 30. Neither has commenced.
Is the Irish speed limit in km/h or mph?
Kilometers per hour. Ireland switched to metric speed limits in 2005, and Northern Ireland, across the border, still uses mph.
The limits are easy. Holding the left side while you read them is the part that takes practice.
You have already learned the table. LeftLane is a browser practice tool for licensed drivers, covering the moments that change when traffic keeps left: pulling out, turning across traffic, and checking your road position afterward, while your attention is somewhere else.
