Cahir–Cashel investigation
Cahir–Cashel: how does road safety compare?
Does the evidence justify calling this Ireland’s most unsafe place to drive?
Not established. The recorded concentration deserves investigation, but a high count or population-based comparison is not a national ranking of driving risk.
This section examines the full Tipperary–Cahir–Cashel municipal district, not just the two towns. It groups historical RSA source coordinates using the fixed 2024 district boundary. The district grouping changed in 2019; this is not a claim that its boundaries were constant throughout the period. Source coordinates may be displaced and do not independently verify exact crash scenes.
Verified mapped record
All three headline figures below are 2016–2024 official mapped records, not the full ten-year district total.
- Source collision records
- 24
- 2016–2024 official mapped records
- People killed
- 26
- in those mapped records
- County mapped share
- 30.6%
- of 85 mapped people killed
The district reference population is 44,532 and the county population 167,895, based on Census 2022. The mapped district has the largest recorded people-killed count among the five Tipperary districts in this grouping. Its 30.6% mapped share and the district’s 26.5% share of county population use different denominators and are context, not traffic exposure or personal risk.
No complete official 2025 district point-map total is available here; research records are not added to these figures.
The answer changes with the years selected
These are derived average annual deaths per 100,000 fixed 2022 residents, not official district rates and not deaths per journey or kilometre. All three comparison periods are shown, including the full available mapped period.
On narrow screens, scroll horizontally to compare all columns.
Three derived average annual deaths per 100,000 fixed 2022 residents| Period | District people killed | District | County | Monaghan | State |
|---|
| 2016–2024 — full mapped period | 26 | 6.49 | 5.63 | 6.81 | 2.99 |
|---|
| 2018–2023 | 23 | 8.61 | 6.25 | 6.38 | 2.84 |
|---|
| 2020–2024 | 13 | 5.84 | 5.00 | 7.05 | 3.01 |
|---|
The district’s crude figure is above the State in these periods. But Monaghan is higher over 2016–2024 and 2020–2024. Selecting only 2018–2023 would hide that contrary result. Comparing one district with counties also does not rank every district or place in Ireland.
How calculated
Window fatalities ÷ fixed 2022 population ÷ calendar years × 100,000. District counts come from spatially assigned RSA map records; county and State counts come from the same frozen CSO ROA15 release. Populations are district 44,532 / Tipperary 167,895 / Monaghan 65,288 / State 5,149,139. This cross-series comparison uses present-boundary grouping and fixed populations, does not adjust for changing population, road users, visitors or traffic, and is sensitive to small numbers. The 2022–2024 figures remain provisional. It is not an exposure-adjusted or causal comparison.
8pm–11.59pm is the largest four-hour group — not a majority
District official source collision records, 2016–2024. Eight of 24 records fall in the largest band. These are collision records, not people killed. Clock-time bands do not establish darkness, visibility, weather or a common cause. No exact day or time is invented.
District official source collision records by four-hour band| Four-hour band | Source collision records |
|---|
| 12am–3.59am | 1 |
|---|
| 4am–7.59am | 3 |
|---|
| 8am–11.59am | 1 |
|---|
| 12pm–3.59pm | 6 |

People killed recorded in this grouping: 12 drivers, 6 passengers, 6 pedestrians and 2 motorcyclists. These are people, not collision records; the source is the same RSA collision dataset.

Questions the records still need to answer
These gaps do not imply that missing records prove no action. They identify what would be needed to test each question without turning context into a cause.
Evidence matrix for unanswered road-safety questions| Question | What is held / what remains needed |
|---|
| Rainfall and drainage | Public station observations provide weather context, not conditions at every crash. Exact event dates/times, nearby hourly or finer observations, drainage/standing-water evidence and comparable non-crash periods are needed to test a rain explanation. Rain is not established or ruled out as a district-level explanation. |
|---|
| Surface materials, grip and roadworks | Job-specific surfacing specifications, material/batch records, friction tests, maintenance dates and exact road segments are needed. A tender, budget allocation or standard specification does not prove what was installed at a crash location. |
|---|
| Clay banks and works timing | The clay-bank question needs dated pre-collision imagery and an exact works and road-segment chronology. Later photographs or an allocation alone cannot establish the earlier condition. No cause or responsibility is inferred. |
|---|
| Traffic and road users | Resident population is not a measure of journeys or vehicle-kilometres. Segment-level traffic counts, road class and time-of-day exposure are needed before comparing driving risk. The TII traffic-count overview supports the availability of traffic-count methods and services, not an actual district denominator here. |
|---|
| Council follow-through | The published plan’s Action 49 sets a 15-day LA16 target after a fatality occurs; the Council’s 2025 report states all 2025 LA16s were completed. Individual forms, dates, findings, recommendations and follow-through records are needed to assess a particular collision. An annual status statement does not establish each case’s timing or outcome. |

Two Kilmoyler entries — do not merge the road identifiers
The Council’s published 2025 works schedule contains:
- L-3151-0, Kilmoyler to Kilnacask: a Restoration Maintenance entry showing length 1,700m and budget €34,588.
- L-31011-0, Kilmoyler: a separate Climate Change Adaptation entry showing €113,240.
These are schedule/budget entries, not proof of actual expenditure, completed works or the material laid. The reviewed records do not establish either entry’s exact link to the bridge approach or that works were underway on 24 April 2025. The next evidence needed is the task order, exact road limits, site dates, delivery/testing records and completion record. No relationship to a collision is inferred.

Source access note
The original RSA 2025 review PDF remains the primary link. Some automated readers challenge it. The RSA publication page is a public alternative for access, not a mirror of the PDF; its third-party text-only reader is labelled separately. No claim here relies on the publication page containing the county figure or every PDF detail.
Status and scope
Evidence reviewed 12 September 2026. All 12 research workstreams are completed as private, review-gated research, with records and gaps tracked separately. It is not a complete crash-by-crash dataset.
Factual record. No finding of causation or responsibility is made here.
