The Road Safety Authority produces official statistics to inform road safety policy and evidence-based interventions. The Authority relies upon collision data collected by An Garda Síochána (AGS) for this purpose. Similarly, Transport Infrastructure Ireland makes use of data, as reported by AGS, to provide evidence for locations within the network to target and prioritise road safety interventions.
Consequently, the primary information requested regarding specific incidents at certain intersections would be held by An Garda Síochána, under the aegis of the Department for Justice, and the Deputy should contact them directly for assistance with his query.
