Why 30km/h?

It’s not only a road safety issue, lower speed limits also:

  • Ensure that traffic moves more smoothly with minimal effects on journey times-
  • Reduce air and noise pollution
  • Reduce carbon emissions by increasing the number of people walking and cycling
  • Encourage young people to move about independently and encourage parents to permit their children to do so
  • Help combat rising levels of obesity by encouraging people of all ages to walk and cycle and by encouraging children to play outdoors
  • Transform our urban and village streets and residential estates from car dominated through-roads to vibrant living ‘people-friendly’ spaces
  • Bring us into line with the rest of Europe where 30km/h, (20 mph in the UK) is fast becoming the default urban speed limit.


The Love 30 Campaign calls on all Local Authorities to introduce more 30km/h zones in urban areas, but particularly in town centres, residential estates, and in the vicinity of schools and places of public assembly. And we call on Dublin City Council to introduce a default 30km/h limit within the canals. A leaflet from the Road Safety Authority shows how lower speed limits dramatically reduce the number of people killed in collisions. They also reduce the severity of injury in any collisions that occur.

Other benefits of lower speed limits:

  • traffic moves more smoothly with minimal effects on journey times
  • air and noise pollution are reduced
  • carbon emissions are reduced by the increase in the number of people walking and cycling
  • young people are encouraged to move about independently and their parents are encouraged to permit their children to do so
  • people of all ages are encouraged to walk and cycle and children are encouraged to play outdoors thus helping to combat rising levels of obesity
  • transform our urban and village streets and residential estates from car dominated through-roads to vibrant living ‘people-friendly’ spaces
  • bring us into line with the rest of Europe where 30km/h, (20 mph in the UK) is fast becoming the default urban speed limit.
