Two ways of measuring

Flintshire looks less dangerous per mile driven than per resident

Divide casualties by the people who live here and Flintshire ranks 129. Divide by the miles actually driven on its roads and it ranks 163 — a difference of 34 places.

That gap runs the other way: relative to the traffic its roads carry, Flintshire 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.

Who is being hurt

Pedestrians, cyclists and riders in Flintshire

These are the road users with the least protection when something goes wrong, and they carry a disproportionate share of the serious injuries. Across 113 collisions in Flintshire, the three groups appear 51 times between them — an involvement rate of 45.1%.

Road userCollisionsShare of all collisions
Pedestrians1412.4%
Cyclists1916.8%
Motorcyclists1815.9%

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.

Darkness, weather and the time of year

When collisions happen in Flintshire

DfT records the light level and road surface at every collision, but publishes neither below national level. These are Flintshire’s own shares over 424 collisions, with the national figure beside each one for comparison.

Share of collisionsFlintshireNationalHow it reads
In darknessAny collision where the officer recorded darkness, lit or unlit.24.8%28.7%below the national figure
In darkness, no street lightingThe rural lighting picture rather than the urban speeding one.9.7%6.3%well above the national figure
On a wet road surfaceWet, damp or standing water at the scene.31.6%24.5%above the national figure
On snow or iceRare everywhere, and concentrated in a handful of authorities.2.4%1.4%well above the national figure

On the darkness share, Flintshire ranks 164 of 192 authorities, counting from the highest.

The winter effect. Collisions in Flintshire run 20.2% lower from November to January than from May to July — against 4.5% lower nationally. That is 91 collisions against 114.

What this does not tell you

  • A share is not a rate. A high darkness share means darkness accounts for more of Flintshire’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.

Benchmark

Flintshire against similar authorities

A national rank compares Flintshire 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 Flintshire is 5 of 6 on casualties per mile driven, against a group median of 76.8.

Common questions

Road risk in Flintshire, answered

How dangerous are the roads in Flintshire?

In the latest official DfT figures, 113 road collisions in Flintshire injured or killed 154 people, 47 of them killed or seriously injured. Measured against the traffic its roads actually carry, that is 62.5 people killed or seriously injured per billion vehicle miles, against a median of 80.5 across the ranked authorities — placing Flintshire 163 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 Flintshire rising or falling?

Across 2021–2025, recorded collisions in Flintshire were down 29.4%, with 2023 the worst year of the period at 189 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 Flintshire's roads?

In Flintshire there were 14 collisions involving pedestrians, 19 involving cyclists and 18 involving motorcyclists, out of 113 in total. Added together that is an involvement rate of 45.1%, 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 Flintshire?

Flintshire is a welsh principal area, 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.
