Support 30 km/h Campaign


On 31st January 2010 Dublin City introduced new byelaws which extended the number of streets in the city with a 30 km/h speed limit to the inner core of the city. This small sensible change has been received a hysterical reaction from the motoring lobby and certain city councillors. As there are no genuine arguements against the 30 km/h zone Dublin Cycling Campaign are opposing calls to remove it.

With your help we can make Dublin an attractive city for all.

How to help?

  1. Email, ring or text your local councillors explaining that this is a better city with the 30km/h limit. Tell them in your own words. The contact details of all councillors are on and there are further facts, figures and sample letters on
  2. Join the Facebook page called We love the 30 kmh zone in Dublin City centre - let’s keep it!
  3. Explain to your friends why it makes sense. Forward them this Support 30 km/h Flyer (Download a .pdf copy and post it in your building or office)
  4. Join the Dublin Cycling Campaign
