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, Winchester’s rate of 298 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 Winchester in 2025: 19 collisions involved a pedestrian, 20 a cyclist and 21 a motorcyclist — overall, 297.8 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.

Winchester's roads are Hampshire's responsibility
Collisions above are counted for Winchester. The body that maintains those roads, sets the speed limits and decides which junctions get fixed is Hampshire — so that is the level at which the record can be compared with anywhere else in Britain.
Per mile driven
132 of 192
Per resident
55 of 188
Risk band
Below average
Five-year trend
up 9.3%
Those two numbers disagree, and that is the story. Hampshire sits 55 of 188 measured per resident but 132 of 192 measured per mile actually driven — a gap of 77 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 Hampshire — 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.
Hampshire’s full road risk record →What actually changes the odds in Winchester
Data is only useful if it changes what you do. These three are picked from Winchester’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 16% of Winchester'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 Winchester are up 37% 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 Winchester's 80 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.
