Road Risk Score
Swansea ranks 124 of 125 towns we score — band A, lowest risk
8.1 people killed or seriously injured per 100,000 residents, 120.3 vehicle crimes per 100,000, 57% of collisions involving someone outside a car, and a five-year trend of -24.8%. How the score works.

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, Swansea’s rate of 32 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 Swansea in 2025: 17 collisions involved a pedestrian, 13 a cyclist and 15 a motorcyclist — overall, 32.1 collisions per 100,000 residents.
Area definition: figures cover 6km radius of the town centre. 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.

Swansea’s full road risk record →What actually changes the odds in Swansea
Data is only useful if it changes what you do. These three are picked from Swansea’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.
Helmet camera
£50–£200
16% of collisions in Swansea involve someone on a bike. In a disputed pull-out, footage from the rider's viewpoint is what settles liability.
How it works →
Alarmed disc lock
£20–£50
Motorcyclists are in 19% of Swansea'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
22% of collisions here involve a pedestrian, and those are the cases most often argued over. Footage removes the argument.
