Pedestrians, cyclists and riders in Milton Keynes
These are the road users with the least protection when something goes wrong, and they carry a disproportionate share of the serious injuries. Across 266 collisions in Milton Keynes, the three groups appear 85 times between them — an involvement rate of 32%.
| Road user | Collisions | Share of all collisions |
|---|---|---|
| Pedestrians | 30 | 11.3% |
| Cyclists | 29 | 10.9% |
| Motorcyclists | 26 | 9.8% |
A single collision can involve more than one of these groups and is then counted in each row, so the rows do not add up to a share of the total.
When collisions happen in Milton Keynes
DfT records the light level and road surface at every collision, but publishes neither below national level. These are Milton Keynes’s own shares over 876 collisions, with the national figure beside each one for comparison.
| Share of collisions | Milton Keynes | National | How it reads |
|---|---|---|---|
| In darknessAny collision where the officer recorded darkness, lit or unlit. | 27.3% | 28.7% | close to the national figure |
| In darkness, no street lightingThe rural lighting picture rather than the urban speeding one. | 2.9% | 6.3% | well below the national figure |
| On a wet road surfaceWet, damp or standing water at the scene. | 21.9% | 24.5% | below the national figure |
| On snow or iceRare everywhere, and concentrated in a handful of authorities. | 0.9% | 1.4% | well below the national figure |
On the darkness share, Milton Keynes ranks 110 of 192 authorities, counting from the highest.
The winter effect. Collisions in Milton Keynes run 14.2% higher from November to January than from May to July — against 4.5% lower nationally. That is 241 collisions against 211.
What this does not tell you
- A share is not a rate. A high darkness share means darkness accounts for more of Milton Keynes’s collisions — not that its roads are more dangerous overall. Read it alongside the casualties-per-mile-driven figure above.
- Condition is recorded, not tested. The officer records the surface and light level at the scene. It is an observation, not a measurement, and it is not a finding that the condition caused the collision.
- Exposure is not controlled for. Fewer people travel at 3am than at 3pm, so a collision in darkness is drawn from a smaller pool of journeys. Without hourly traffic counts, these shares describe when collisions happen rather than how risky an hour is.

Milton Keynes against similar authorities
A national rank compares Milton Keynes with places that may be nothing like it. This is the comparison a council actually uses: its statistical nearest neighbours — the authorities ONS identifies as most similar on population, economy and demography, restricted to the same tier, so counties are compared with counties. Within this group Milton Keynes is 8 of 9 on casualties per mile driven, against a group median of 58.9.
| Authority | KSI / bn miles | Score | National rank |
|---|---|---|---|
| Reading | 121.1 | 76.8 | 4 |
| Bedford | 75.9 | 55.9 | 73 |
| Coventry | 75.8 | 48.8 | 103 |
| Bracknell Forest | 67.5 | 44.7 | 124 |
| Swindon | 58.9 | 25.3 | 182 |

| West Northamptonshire | 37.5 | 33.3 | 164 |

Road risk in Milton Keynes, answered
How dangerous are the roads in Milton Keynes?
In the latest official DfT figures, 266 road collisions in Milton Keynes injured or killed 339 people, 40 of them killed or seriously injured. Measured against the traffic its roads actually carry, that is 38.8 people killed or seriously injured per billion vehicle miles, against a median of 80.5 across the ranked authorities — placing Milton Keynes 189 of 192 authorities on our combined score, where 1 is the highest risk. The score weighs that rate alongside who is being hurt, the five-year trend and how often a serious collision proves fatal, so the rank is not the rate alone.
Are road casualties in Milton Keynes rising or falling?
Across 2021–2025, recorded collisions in Milton Keynes were down 18.9%, with 2022 the worst year of the period at 345 collisions. Year-to-year movement in a single authority is noisy, so the five-year direction carries more than any single year's change.
Who is being hurt on Milton Keynes's roads?
In Milton Keynes there were 30 collisions involving pedestrians, 29 involving cyclists and 26 involving motorcyclists, out of 266 in total. Added together that is an involvement rate of 32%, though a collision involving two of those groups is counted in both figures, so it is a comparable index rather than a clean share.
Who is responsible for road safety in Milton Keynes?
Milton Keynes is a unitary authority, and is the highway authority for its own roads. That means it sets local speed limits, designs junctions and crossings, and decides safety scheme spending. Motorways and most trunk roads are managed separately by National Highways in England, Transport Scotland, or the Welsh Government, so the worst road in an area is often not the council's to change. Enforcement sits with the local police force.
Where does this data come from?
DfT STATS19, the record police complete at the scene of every injury collision, published annually under the Open Government Licence, combined with DfT's own road traffic estimates for the mileage denominator. Collision, casualty and KSI counts on this page are for 2025; only the trend compares 2021–2025. STATS19 counts collisions police attended and recorded, so collisions never reported do not appear, and under-reporting is known to be worst for cyclists and for slight injuries.
