Speed limitIreland
5. Speed limit
A speed limit is the maximum legal speed permitted on a road, lane or within a designated area. It may be established by general traffic law or indicated by fixed, variable or temporary traffic signs.
A speed limit is a maximum, not a target speed. Drivers must travel more slowly whenever traffic, visibility, weather, road conditions, vulnerable road users or the condition of the vehicle make the maximum permitted speed unsafe.

Which general speed limits should car drivers know in Ireland?
For an ordinary car, current general limits include 50 km/h in built-up areas, 60 km/h on rural local roads, 80 km/h on regional roads, 100 km/h on national roads and 120 km/h on motorways. Lower special limits apply where established. Reductions are being implemented in stages: use current signs and rules rather than treating a planned change as already universal.

Did Ireland’s rural local-road default change to 60 km/h?
Yes. The default on rural local roads was reduced from 80 to 60 km/h on 7 February 2025. Local roads are commonly identified by an L number or can be unnumbered. Observe any applicable special limit and remember that 60 km/h can still be too fast for a narrow rural road.

Are planned Irish urban reductions already the default on every street?
No. Urban reductions are being implemented through local special speed-limit bye-laws, with a 31 March 2027 implementation target. Follow the current signs and applicable local rules; the review does not make every street 30 km/h immediately.
