Dublin is the latest 30 km/h city

Plans to cut speed limits to 30 km/h on residential streets throughout Dublin were approved in December.

The lower limits will be introduced on a step-by-step basis from March 2017 and will apply on almost all roads in Dublin and its surrounding suburbs.

The council’s head of traffic and transport Dick Brady said the overriding principle in relation to a 30km/h default speed limit was road safety: “It’s in the interest of road safety we would be recommending these new speed limits. We are talking about setting speed limits adjacent to residential areas and school in order to try to ensure the safety of residents and children.”

Motoring groups opposed the plans.
