Accident hotspots in Wiltshire: where crashes cluster
Police recorded 1,027 road collisions in Wiltshire in 2025. We mapped every one to find the junctions and roads where they concentrate.

Road Risk Score
Wiltshire ranks 68 of 125 towns we score — band C, around average
53.7 people killed or seriously injured per 100,000 residents, 13.5 vehicle crimes per 100,000, 34.4% of collisions involving someone outside a car, and a five-year trend of +21.5%. How the score works.
Vulnerable road users in Wiltshire (2025)
106 of Wiltshire's 1,027 collisions (10%) involved pedestrians; 92 of Wiltshire's 1,027 collisions (9%) involved cyclists; 155 of Wiltshire's 1,027 collisions (15%) involved motorcyclists. Together those collisions left 145 people killed or seriously injured.
| Road user | Collisions | Share of all collisions | Killed or seriously injured | Serious-outcome rate |
|---|---|---|---|---|
| Pedestrians | 106 | 10% | 35 | 33% |
| Cyclists | 92 | 9% | 34 | 37% |
| Motorcyclists | 155 | 15% | 76 | 49% |
94 of Wiltshire’s collisions in 2025 involved a child casualty.
Wiltshire’s busiest collision clusters (2025)
Each circle is a ~100m cluster of police-reported collisions. Larger circles = more collisions; red = at least one death. Click a circle for details.
The short answer
Wiltshire recorded 1,027 police-reported collisions in 2025 — rising (+16.7% on 2024), or about 198 per 100,000 residents. Its most stubborn risk is Malmesbury Road, Cricklade, a hotspot in 4 of the last 5 years.

Wiltshire’s junctions that stay dangerous
These locations recorded multiple collisions in at least four of the last five years (2021–2025) — a persistent pattern, not a one-off bad year.

What to do with this: if your regular routes cross the junctions above, they deserve extra care at peak times — these aren’t random locations, they’re where collisions repeat. For context, Wiltshire’s rate of 198 per 100,000 residents compares with an average of 220 across the 125 areas we track. A junction with a documented five-year history is also the strongest evidence a campaign can put in front of a councillor.
Vulnerable road users in Wiltshire in 2025: 106 collisions involved a pedestrian, 92 a cyclist and 155 a motorcyclist — overall, 197.5 collisions per 100,000 residents.
Area definition: figures cover Wiltshire unitary authority (ONS). Per-100k rates use the mid-2023 ONS population estimate for the named town or district; where the area is radius-defined, treat the rate as indicative.
These figures come from the Department for Transport’s STATS19 dataset — every collision reported to the police in 2025 — clustered to roughly 100 metres and labelled via OpenStreetMap. Only police-reported incidents are included, so minor damage-only bumps are undercounted. See the full UK hotspots analysis for the national picture and methodology.

How Wiltshire compares nationally
Wiltshire is the highway authority for these roads, which means the same body counted in the national comparison below is the one that maintains them.
Per mile driven
96 of 192
Per resident
20 of 188
Risk band
Above average
Five-year trend
up 21.5%
Those two numbers disagree, and that is the story. Wiltshire sits 20 of 188 measured per resident but 96 of 192 measured per mile actually driven — a gap of 76 places. Measured against the traffic the network actually carries rather than the number of people living beside it, the record is better than the headline per-head figure implies.
The full record for Wiltshire — severity-adjusted casualties, the breakdown of who is being hurt, the darkness and ice profile, and a comparison against its ONS statistical neighbours rather than the national average — is on its own page.
Wiltshire’s full road risk record →What actually changes the odds in Wiltshire
Data is only useful if it changes what you do. These three are picked from Wiltshire’s own figures above, each with the number that prompted it. Every guide explains how the thing works before it suggests buying anything, and most cost less than a third of a typical insurance excess.
Alarmed disc lock
£20–£50
Motorcyclists are in 15% of Wiltshire's collisions, and bikes are also lifted rather than ridden away. An alarmed disc lock covers the theft half for about £30.
How it works →
Dashcam (parking mode)
£50–£150
Collisions in Wiltshire are up 22% across the period. A dashcam with parking mode is the cheapest way to keep a disputed claim from becoming a 50/50 split.
How it works →
Faraday key pouch / box
£9–£25
Even at Wiltshire's 14 vehicle crimes per 100,000 residents, relay theft is the method that needs no tools and leaves no damage. The pouch is the cheapest thing that stops it.
