This page is built from the Department for Transport's STATS19 open data, the record of every road casualty reported to the police in Great Britain. We've taken the 2025 final release and counted casualties involving motorcyclists and cyclists on each numbered road.
You'll see the term KSI throughout. It means killed or seriously injured, the measure road safety professionals use most often.
Some honest caveats before the tables. Long roads appear high up partly because they're long: the A6 runs from Luton to Carlisle, so it racks up more of everything. These are counts, not rates per mile travelled, so a road with fewer casualties isn't automatically safer. And police data undercounts non-fatal rider casualties, because plenty of spills never get reported. Treat this as a map of where harm happens, not a league table of roads to avoid.
Looking for your area?
We've split the same 2025 figures across all 44 police force areas in Britain, with the worst road for motorcyclists and cyclists in each one.
See the regional breakdownWhat changed vs 2024
Motorcyclist deaths rose 14% in 2025 while motorcycle traffic barely changed. Seventy per cent of motorcyclist deaths happen on rural roads, which carry 38% of traffic. Cyclist deaths fell slightly, but cyclist serious injuries rose. The A38 replaced the A6 as the road with the most motorcyclist KSI casualties, while the A4 stayed the worst road for cyclists.

These are counts, not rates
Long roads carry more traffic and rack up more casualties. We have now measured casualties against how far people actually ride on each road, and the ranking changes completely.

Fact 1 of 2
386 motorcyclists were killed on Britain's roads in 2025, up 14% on 2024.

Before you share this. These are counts of people from the police record of reported road casualties, not risk rates, and not an allegation against anyone. The source is included in the share text so it travels with the number. What you write alongside it is yours, not ours.
Methodology
Figures are computed from the DfT's road casualty statistics casualty and collision files for 2025 (data.dft.gov.uk road-accidents-safety-data), the final release. Casualties are assigned to the first road of the collision. Roads without a number, including unclassified and C roads, are excluded. Severity is as reported by the police and hasn't been adjusted.

If you ride these roads
- Most rider collisions happen at junctions and involve another vehicle that didn't see the bike. Position yourself to be seen and plan an exit before you need one.
- Ease off through built-up stretches and near side roads. Urban A roads dominate these tables, and they're where traffic mixes most.
- In poor light and wet weather, assume you haven't been spotted. Slow down and give yourself room.
- Wear decent kit on every ride, however short. The numbers don't care how close to home you are.
- On a bike you've just bought or borrowed, take the first few miles gently while you learn its brakes and tyres.
