Dublin, Ireland – Dublin City Council is introducing significant new bylaws that will fundamentally change driving and commuting across the capital. In a major move aimed at enhancing road safety and reducing traffic fatalities, the speed limit on almost all roads in Dublin city is set to be reduced.
The New Regulatory Change
Under the new regulations, the default speed limit across the majority of the city’s road network will be lowered to 30 kilometres per hour (30km/h).
- The Change: Dublin City Council is implementing new bylaws to dramatically cut the maximum speed permitted on urban roads.
- New Limit: Almost all roads in Dublin city are expected to adopt the new 30km/h limit, replacing the previous higher limits in many areas.
- Impact: This measure is intended to minimize the severity of collisions and create a safer environment for cyclists, pedestrians, and all road users.
This move follows a growing trend in major European cities to implement lower default speed limits as a core strategy for achieving Vision Zero—the goal of eliminating all traffic deaths and serious injuries. The new rules are set to impact daily commutes for thousands of drivers and shape the future of urban mobility in Dublin.
