Legislative hurdles to making 30 the default

New speed limits are set to be introduced across Dublin city in an attempt to make the city safer. The 30kmh speed limit currently applies in parts of the city centre in Dublin 1, Dublin 2, Marino in Dublin 3 and Irishtown and Ballsbridge in Dublin 4. But will this work across our capital city?

All to discuss with Olivia Kelly, Dublin Editor of The Irish Times.
