Holywood Bypass: Collisions, Speed Cameras & Police Enforcement
An evidence-led investigation of historical injury collisions near Holywood Bypass, published speed enforcement, police activity and what the available figures can—and cannot—tell us about road safety.
These are injury collisions recorded within 100 metres of the mapped DfI Holywood Bypass sections. Some could have occurred on adjoining roads or junctions. They are not confirmed collisions on the bypass itself, and they do not include every non-injury crash.
Thirteen years of nearby collision history
Annual police-recorded injury collisions within 100 metres of the mapped road, from 2013 through 2025.

What happened to injury severity?
Across the available 2013–2025 records, 1 collision was classified as fatal, 10 as serious, and 92 as slight within the 100-metre corridor. These are collision severity classifications, not counts of individual people killed or injured.
The figures reflect recorded injuries in the surrounding corridor; without traffic-volume data they cannot establish the risk per journey.
Speed van deployments and speeding detections
PSNI disclosures provide evidence of enforcement associated with Holywood Bypass. Each figure below relates to the specified reporting period, not the current position or operating status of a camera van.
Date or reporting period: 2024-04-01 to 2025-03-31
38 recorded deployments during this reporting period.
Date or reporting period: 2025-05-28
94 speeding detections.
84 detections resulted in notices of intended prosecution, according to the cited disclosure.
Date or reporting period: 2025-11-23
11 speeding detections during a 1-hour observation .
Why did police carry out enforcement here?
The disclosed site was introduced following local speeding concerns, rather than collision statistics being the stated selection basis.
Are the speed cameras making a difference?
Historical enforcement is documented. Effectiveness is not yet established. PSNI has published evidence of deployments and speeding detections at Holywood Bypass. Our separate collision analysis shows how recorded injury collisions in the surrounding 100-metre corridor varied over 13 years.
Those two findings do not prove that the enforcement reduced, increased or had no effect on crashes. A reliable assessment would need the intervention dates, comparable road sections, traffic volumes and other changes affecting road safety.
Past deployments do not tell us whether a camera van is currently working or present.
How PureCar carried out this analysis
Collision locations come from PSNI's injury-collision records for 2013–2025. PureCar measured straight-line distances from those recorded points to mapped DfI Holywood Bypass road sections and counted records within a 100-metre corridor. Historical enforcement findings are drawn separately from the linked PSNI disclosures.
The DfI road geometry identifies the analysis corridor. The PSNI camera-road name does not establish a precise camera parking point. Roadworks, traffic volumes, unreported crashes and other influences have not been controlled for.
Is the collision trend improving or worsening?
These are police-recorded injury collisions within 100 metres of the mapped Holywood Bypass road sections. Equal-length periods provide a more useful comparison than looking at one year alone.
Recorded collisions were 16.3% lower in 2019–2024 compared with 2013–2018. This describes recorded collisions, not changes in risk per vehicle journey.

People killed and injured
The following figures count individual casualties associated with the 103 recorded injury collisions in this mapped Holywood Bypass investigation.
These are PSNI casualty-severity counts for 2013–2025, within 100 metres of the mapped bypass sections. They are not a lifetime fatality total for the road. A fatal collision can involve more than one death.
People injured and vehicles involved
We linked the collision references directly to the original PSNI casualty and vehicle datasets.
Casualty totals count individual PSNI casualty records. They are distinct from the number of collisions classified as fatal or serious. These figures do not establish fault.

These are recorded collision locations within 100m of the mapped bypass, not necessarily collisions on the bypass. The lines use DfI road geometry and the points use original PSNI grid coordinates. No camera marker is shown because its exact position is not verified.

Understanding the Holywood Bypass road safety evidence
This investigation analyses 103 police-recorded injury collisions within 100 metres of mapped Holywood Bypass sections during 2013–2025, linked to 187 casualty records and 220 vehicle records. Some incidents may have occurred on adjoining roads or junctions. The available evidence does not establish that speed enforcement caused changes in collision numbers.
