West Lothian looks less dangerous per mile driven than per resident
Divide casualties by the people who live here and West Lothian ranks 111. Divide by the miles actually driven on its roads and it ranks 174 — a difference of 63 places.
That gap runs the other way: relative to the traffic its roads carry, West Lothian does less harm than its casualty count per resident implies. Places with heavy local travel and few through routes tend to look worse per head than the volume of driving warrants. 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 West Lothian
These are the road users with the least protection when something goes wrong, and they carry a disproportionate share of the serious injuries. Across 165 collisions in West Lothian, the three groups appear 59 times between them — an involvement rate of 35.8%.
| Road user | Collisions | Share of all collisions |
|---|---|---|
| Pedestrians | 22 | 13.3% |
| Cyclists | 10 | 6.1% |
| Motorcyclists | 27 | 16.4% |
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 West Lothian
DfT records the light level and road surface at every collision, but publishes neither below national level. These are West Lothian’s own shares over 439 collisions, with the national figure beside each one for comparison.
| Share of collisions | West Lothian | National | How it reads |
|---|---|---|---|
| In darknessAny collision where the officer recorded darkness, lit or unlit. | 28.2% | 28.7% | close to the national figure |
| In darkness, no street lightingThe rural lighting picture rather than the urban speeding one. | 13.2% | 6.3% | roughly double the national figure |
| On a wet road surfaceWet, damp or standing water at the scene. | 36.4% | 24.5% | well above the national figure |
| On snow or iceRare everywhere, and concentrated in a handful of authorities. | 3.2% | 1.4% | more than double the national figure |
On the darkness share, West Lothian ranks 87 of 192 authorities, counting from the highest.
The winter effect. Collisions in West Lothian run 18% lower from November to January than from May to July — against 4.5% lower nationally. That is 105 collisions against 128.
What this does not tell you
- A share is not a rate. A high darkness share means darkness accounts for more of West Lothian’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.

West Lothian against similar authorities
A national rank compares West Lothian 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 West Lothian is 7 of 8 on casualties per mile driven, against a group median of 61.9.

|---|---|---|---|
| South Lanarkshire | 71.9 | 45.8 | 122 |
| Fife | 67.1 | 38.9 | 142 |
| Renfrewshire | 65.1 | 48.3 | 107 |

Road risk in West Lothian, answered
How dangerous are the roads in West Lothian?
In the latest official DfT figures, 165 road collisions in West Lothian injured or killed 248 people, 63 of them killed or seriously injured. Measured against the traffic its roads actually carry, that is 53 people killed or seriously injured per billion vehicle miles, against a median of 80.5 across the ranked authorities — placing West Lothian 174 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 West Lothian rising or falling?
Across 2021–2025, recorded collisions in West Lothian were down 2.4%, with 2022 the worst year of the period at 174 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 West Lothian's roads?
In West Lothian there were 22 collisions involving pedestrians, 10 involving cyclists and 27 involving motorcyclists, out of 165 in total. Added together that is an involvement rate of 35.8%, 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 West Lothian?
West Lothian is a scottish council, 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.
