Ms Muireann O'Dea:

Two fundamental legislative changes are needed. The first is to change the current default of 50 km/h in built-up areas to 30 km/h. That makes it simpler for all local authorities. They know what the default is and only need to discuss roads where a higher speed limit is more appropriate.

The second change relates to the definition of "built-up areas". It is out of date and many newer towns are not included. That list of built-up areas needs to be updated.
