Northern Ireland road deaths fell in 2025 — so why did serious injuries rise?
PureCar original analysis | 23 October 2026. An analysis of the diverging 2025 road safety figures shows why a lower death toll is not the same as safer roads. This report separates recorded evidence from analysis, so readers can understand not only the headline but also the limits of the data.
The headline conceals two different stories
Northern Ireland recorded 56 road deaths in 2025, down from 69 in 2024. That is a reduction of 13 people, or about 19%. On its own, the decline is welcome. Yet the number of seriously injured people climbed from 939 to 1,066, an increase of 127 or roughly 14%. Those outcomes should be read together. A road safety strategy cannot be judged solely by whether fewer collisions end in death if more people experience life-changing injuries.
What changed in the wider casualty picture
Across the year the PSNI recorded 5,015 injury collisions, compared with 4,753 in 2024: 262 more incidents, a rise of around 5.5%. Total casualties increased from 7,494 to 7,879. The severe-injury rise was much steeper than the rise in collisions, which matters when considering emergency response, rehabilitation and long-term support. The total of people killed or seriously injured reached 1,122 in 2025 versus 1,008 in 2024.
The 2030 test is tougher than a single-year comparison
The Department for Infrastructure reports that deaths were 17% below its strategy baseline while serious injuries stood 42% above their baseline. Those benchmarks are not previous-year figures: they come from an earlier reference period used to measure long-term progress. A reader looking at the death total alone could conclude the strategy is comfortably ahead. The serious-injury measure points the other way.
What needs investigating next
The important follow-up questions concern collision severity and prevention: are junction layouts, road markings and crossing conditions contributing to serious injuries; which modes of transport account for the harm; and are local interventions reaching routes where injury patterns repeat? Aggregate annual statistics cannot answer those questions on their own. They identify where examination should begin. PureCar’s road-level reports can help readers explore mapped injury-collision records, while the underlying police data remain the authority for individual entries.
The severity gap, calculated
PureCar calculated the change using the published PSNI annual totals. In 2024, killed-or-seriously-injured (KSI) casualties represented 1,008 of 7,494 casualties, around 13.5%. In 2025, the equivalent was 1,122 of 7,879, around 14.2%. That is an increase of approximately 0.8 percentage points in the share of reported casualties classified as killed or seriously injured. This ratio describes recorded casualty severity; it is not a probability that any individual journey will end in injury.
| Measure | 2024 | 2025 | Change |
|---|---|---|---|
| Injury collisions | 4,753 | 5,015 | +5.5% |
| Fatalities | 69 | 56 | −18.8% |
| Serious injuries | 939 | 1,066 | +13.5% |
| KSI casualties | 1,008 | 1,122 | +11.3% |
It would be wrong to conclude that a particular treatment failed or that crashes became more severe in a clinical sense from this single ratio. Injury reporting, exposure and case mix all need assessment. But the divergence is large enough to justify a separate serious-injury performance measure alongside the headline death toll.
About the evidence
This PureCar analysis uses officially published PSNI and Northern Ireland departmental statistics. The police series covers injury road traffic collisions reported to police; it does not capture every non-injury bump, near miss or unreported incident. A collision is an event and a casualty is a person, so the two totals must not be used interchangeably. The figures are historical and do not indicate conditions on any route right now.
What the figures cannot prove
A higher count in a place or group does not, by itself, establish greater risk per vehicle journey, per mile travelled or per person. The appropriate denominator and road-user exposure data would be required for that conclusion. Nor can the published summary alone establish responsibility for individual incidents. Where this article raises questions about infrastructure, enforcement or road-user behaviour, those are reporting questions unless a cited source confirms an answer.
