New speed limits and signage for Dublin roads and housing estates are to be introduced in August.

On Dublin's rural roads some 80km/h signs will be replaced with new ones indicating drivers must drive at appropriate speeds.

In Dublin housing estates and other built up areas around Dublin provision is being made for slow zones. Currently the legal speed limit in Dublin housing estates is 50kmh.

New signs will indicate to drivers that the limit is 30km/h and will warn of vulnerable people in the area like children at play.
