Speed Limits in Dublin City

Back to Travel and Transport

Dublin City Council is constantly working for and with the people of Dublin to improve road safety on all streets of the city.

While road safety is important to all road users, cyclists and pedestrians are amongst those who are the most at risk of sustaining injuries in accidents. The extent and severity of injuries are linked to vehicle speed. The higher the speed, the more serious injuries are sustained. Therefore, traffic speed reduction for all vehicles plays a crucial role in improving road safety on the city streets.

In response to this, Dublin City Council took a proactive approach and implemented 30km/h speed limits for all residential areas of Dublin. The most recent Dublin City Council Special Speed Limit Bye-Laws were adopted at the January 2020 Council meeting. 

Current Speed Limits

The default speed limit for most roads within the Dublin City Council area is 50km/h. Speed limit signs are erected at all points where there is a speed limit change. The enforcement of the speed limits is a matter for An Garda Síochána.

Dublin City Council has progressively introduced a 30km/h speed limit to many areas of the city, and Dublin City Council implemented 30km/h speed limits in all the residential areas as per approved Phase 4 - Special Speed Limit Bye-Laws 2020. Please see the map below of our Phase 4 Special Speed Limit Bye-Laws 2020.
