UK road risk, from the official record
Government publishes the evidence on how dangerous Britain's roads are across half a dozen datasets that never meet each other. We join them up: where collisions happen, which roads and vehicles are involved, how drivers are tested, and where vehicles are stolen. 2,650 numbered roads and 125 towns and cities, free to use, every figure traceable to its source file.
Where the danger is
Every police-reported injury collision, matched to the place it happened.
Road risk by area

What you drive
Vehicle condition and design are road safety questions: how models fail their MOT, and what happens to the people inside them in real crashes.
Who is on the road
Competence is measured before anyone drives alone, and pass rates vary by more than thirty points between centres.
Vehicle crime, and the defences that work against it
Vehicle crime is the other way people lose a car. The same records that show where it happens also show which defences are worth buying.

Why one site covers all four
Road danger is not one number. A collision happens at a place, involves a vehicle of a certain age and condition, and a driver who was tested somewhere. Government publishes each of those separately: the Department for Transport holds the collision records, the DVSA holds MOT results and test pass rates, police forces publish street-level crime. None of it is joined up, and none of it arrives in a form a resident, a councillor or a journalist can use.
That is the work: cleaning the files, matching records to places, and publishing the result with the method attached. Everything here is derived from Open Government Licence data and free to reuse with attribution. Where a dataset cannot answer a question, we say so on the page rather than filling the gap. See the methodology, the free API, or commission an analysis.
