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, Northampton’s rate of 204 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 Northampton in 2025: 85 collisions involved a pedestrian, 35 a cyclist and 59 a motorcyclist — overall, 203.6 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.

Northampton's roads are West Northamptonshire's responsibility
Collisions above are counted for Northampton. The body that maintains those roads, sets the speed limits and decides which junctions get fixed is West Northamptonshire — so that is the level at which the record can be compared with anywhere else in Britain.

Those two numbers disagree, and that is the story. West Northamptonshire sits 85 of 188 measured per resident but 164 of 192 measured per mile actually driven — a gap of 79 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 West Northamptonshire — 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.
West Northamptonshire’s full road risk record →What actually changes the odds in Northampton
Data is only useful if it changes what you do. These three are picked from Northampton’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.
Faraday key pouch / box
£9–£25
Northampton records 273 vehicle crimes per 100,000 residents, above the median of the towns we track. Keyless relay theft is the leading route into modern cars, and a signal-blocking pouch ends that method outright for under a tenner.
How it works →
Steering wheel lock
£40–£70
Vehicle theft is target selection: thieves work a street and take the easiest car. A visible attack-rated bar moves your car down that list before anyone touches it.
How it works →
Alarmed disc lock
£20–£50
Motorcyclists are in 13% of Northampton's collisions, and bikes are also lifted rather than ridden away. An alarmed disc lock covers the theft half for about £30.
