Notes to editors:
- Killed and Seriously Injured (KSI) Casualties caused by Excessive Speed in Northern Ireland 2019-2023 is part of a suite of problem profiles produced over the last few years.
- The majority of the data within the report derives from the Police Service of Northern Ireland (PSNI) Road Traffic Collision Statistics and is typically based on the period 1 January 2019 to 31 December 2023. The report analyses official data sources and reports on trend information for speeding KSI casualties from 2004 examining how speeding KSI casualties compare with overall road traffic collision KSI casualties over time. It provides context comparing speeding and other causes for KSI casualties for the five-year period, 2019-2023. The profile of speeding KSI casualties is then examined looking at the age and sex of KSI casualties as well as looking at who is responsible for speeding collisions. The time of day by day of the week when KSI casualties occurred is examined as well as investigating what month of the year casualties occurred. The speed limit speeding KSI collisions occur on is examined as well as where they occur. A mapping section provides the location of speeding KSI collisions. The final section of the report examines speeding offences recorded by the PSNI and Road Safety Partnership.
- The Department will use the information presented in this publication to support policy development. The report provides departmental officials with the current picture of Speeding KSI casualties and provides evidence to allow them to consider the best ways to try to reduce casualty numbers.
