Bristol's serious collisions, ward by ward
645 people were killed or seriously injured on Bristol's roads over 2021–2025, 30 of them fatally. We mapped all 619 collisions to their council ward. Half of them happened in just 8 of the city's 34 wards.
The short answer
Serious road injury in Bristol is concentrated, not spread. Central alone recorded 88 serious or fatal collisions in five years, more than the ten safest wards put together (76). Collisions track the road network rather than population: the A38, A4 and A432 run through most of the worst-affected wards. And the direction of travel is wrong, with the city total up 129% since 2021.
Every figure here comes from the Department for Transport’s STATS19 records, the police record of injury collisions, point-matched to current ONS ward boundaries. Slight-injury collisions are excluded: this counts people killed or seriously injured (KSI). Full method.

Five findings from 619 serious collisions
1. Half the city’s serious injuries happen in a quarter of its wards
8 of Bristol’s 34 wards account for half of every serious and fatal collision in the city. The five worst (Central, Avonmouth and Lawrence Weston, Lawrence Hill, Ashley, Southville) carry 245 between them, which is 40% of the total from 15% of the wards. At the other end, the 17 wards making up the safer half record 159 between them.
2. The trend is going the wrong way
Serious and fatal collisions rose from 89 in 2021 to 204 in 2025, a change of +129% across the period, peaking at 204 in 2025. Traffic volumes recovering after 2021 explain part of any rise, but not all of it on roads whose layout has not changed.

3. One road runs through the problem: the A38
Counting every ward it passes through, the A38 accounts for 47 serious and fatal collisions across 10 separate wards. A corridor-wide approach would reach more people than any single junction scheme.
Counts the first road recorded on each collision, so collisions on unclassified roads are absent from this table but included in ward totals.
4. Volume and lethality are different problems
Central records the most serious collisions in Bristol (88), but Avonmouth and Lawrence Weston is where a collision is most likely to kill: 5 of its 53 serious collisions were fatal, a rate of 9%, against a city average of 5%. 20 wards recorded no fatal collision at all in five years. Speed is usually what separates the two groups: outer wards see fewer collisions, at higher speeds, with worse outcomes.
5. Some wards are moving fast, in both directions
Comparing 2021 with 2025 for wards with a meaningful base, the swings are large enough to be worth asking about before they harden into a trend.

Wards with fewer than five collisions in 2021 are excluded: percentage swings on tiny numbers are noise, not signal.
