A 30km/hr special speed limit is to be put in place in 424 Kerry housing estates, and in Tralee and Killarney town centres.
50km/hr speed limits will now be in place around all schools.
These changes are laid down in the new Kerry County Council Road Traffic Special Speed Limit Bye-Laws 2018, which have been adopted by councillors.
The bye-laws will come into place in four months’ time.
Kerry County Council carried out an extensive review of existing speed limits on regional and local roads and recommended changes, and Transport Infrastructure Ireland reviewed national roads.
The new bye-laws provide for a 30km/hr special speed limit in 424 housing estates in the county, and in Tralee and Killarney town centres.
During a period of public consultation last summer, 31 submissions were received on special limits at national schools outside built up areas.
A maximum 50km/hr speed limit will now be in place for all schools on local and regional roads in Kerry outside of towns and villages – any school within a town or village would already have a 50km/hr limit around it, while for schools on national roads, the limit will apply only during school hours.
Other changes include a 60km/hr limit on the Tralee approach to Farranfore on the N22; on the N69 Listowel Limerick road in Tarbert; on the Kilcummin road on the approach to its junction with the N22; and on the N70 Ring of Kerry road in Glenbeigh at the turn off for Rossbeigh.
