St. Helens looks more dangerous per mile driven than per resident
Divide casualties by the people who live here and St. Helens ranks 166. Divide by the miles actually driven on its roads and it ranks 36 — a difference of 130 places.
That gap is the signature of a place that absorbs other people’s traffic. Relative to the volume its roads carry, the harm done here is worse than the resident population suggests, which is the pattern you would expect where a trunk route, a commuter corridor or a visitor economy brings in drivers who are not counted in the denominator everyone else uses. Neither number is the true one. Which you should use depends on whether you are asking how safe it is to live somewhere or how safe it is to drive there.

Pedestrians, cyclists and riders in St. Helens
These are the road users with the least protection when something goes wrong, and they carry a disproportionate share of the serious injuries. Across 244 collisions in St. Helens, the three groups appear 131 times between them — an involvement rate of 53.7%.
| Road user | Collisions | Share of all collisions |
|---|---|---|
| Pedestrians | 71 | 29.1% |
| Cyclists | 32 | 13.1% |
| Motorcyclists | 28 | 11.5% |
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 St. Helens
DfT records the light level and road surface at every collision, but publishes neither below national level. These are St. Helens’s own shares over 705 collisions, with the national figure beside each one for comparison.
| Share of collisions | St. Helens | National | How it reads |
|---|---|---|---|
| In darknessAny collision where the officer recorded darkness, lit or unlit. | 26.4% | 28.7% | close to the national figure |
| In darkness, no street lightingThe rural lighting picture rather than the urban speeding one. | 2.1% | 6.3% | a small fraction of the national figure |
| On a wet road surfaceWet, damp or standing water at the scene. | 25.2% | 24.5% | close to the national figure |
| On snow or iceRare everywhere, and concentrated in a handful of authorities. | 1.4% | 1.4% | close to the national figure |
On the darkness share, St. Helens ranks 136 of 192 authorities, counting from the highest.
The winter effect. Collisions in St. Helens run 4.3% lower from November to January than from May to July — against 4.5% lower nationally. That is 179 collisions against 187.
What this does not tell you
- A share is not a rate. A high darkness share means darkness accounts for more of St. Helens’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.

St. Helens against similar authorities
A national rank compares St. Helens 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 St. Helens is 6 of 10 on casualties per mile driven, against a group median of 89.8.

|---|---|---|---|
| Sefton | 137 | 65.5 | 33 |
| Wakefield | 103.4 | 60.8 | 54 |
| Rotherham | 93.7 | 56 | 72 |

Road risk in St. Helens, answered
How dangerous are the roads in St. Helens?
In the latest official DfT figures, 244 road collisions in St. Helens injured or killed 301 people, 46 of them killed or seriously injured. Measured against the traffic its roads actually carry, that is 87.1 people killed or seriously injured per billion vehicle miles, against a median of 80.5 across the ranked authorities — placing St. Helens 36 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 St. Helens rising or falling?
Across 2021–2025, recorded collisions in St. Helens were up 13.0%, with 2025 the worst year of the period at 244 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 St. Helens's roads?
In St. Helens there were 71 collisions involving pedestrians, 32 involving cyclists and 28 involving motorcyclists, out of 244 in total. Added together that is an involvement rate of 53.7%, 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 St. Helens?
St. Helens is a metropolitan borough, 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.
What actually changes the odds in St. Helens
Data is only useful if it changes what you do. These three are picked from St. Helens’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 11% of St. Helens'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 St. Helens are up 13% across the period. A dashcam with parking mode is the cheapest way to keep a disputed claim from becoming a 50/50 split.
