Where the recorded collisions were
STATS19 first_road_class A (3) or A(M) (2) and first_road_number = 1, so the A1(M) sections are included; collisions where the road is only the second road are not included. map points are fatal and serious collisions only; hexagons (Uber H3, about 5 km²) hold every recorded collision with coordinates.

Period comparison
2021–2022 compared with 2024–2025
Yearly averages of recorded counts. A change can come from traffic volumes, roadworks or recording changes as well as safety — the data cannot separate them.

Source and limitations
About this data
- Source: Department for Transport, Road Safety Data (STATS19), police-reported personal injury collisions in Great Britain — Open Government Licence v3.0. Prepared 2026-09-23.
- Matching: STATS19 first_road_class A (3) or A(M) (2) and first_road_number = 1, so the A1(M) sections are included; collisions where the road is only the second road are not included.
- Counts are police-reported collisions with at least one injured casualty; damage-only crashes are not in STATS19.
- A collision is counted once; casualties are counted from the casualty table.
- Changes between years can reflect reporting changes (for example police forces moving to the CRASH reporting system) as well as real change.
- Hexagons are Uber H3 cells; a busy cell is not a measure of risk because traffic volumes are not included.
- The route line on the map is a simplified sketch of the corridor; crashes are placed at the coordinates the source recorded.

Questions
A1 accident history — FAQ
Where does the A1 accident history come from?
From the Department for Transport's STATS19 road safety data: police-reported collisions in which at least one person was injured. A collision is counted for the A1 when STATS19 records it (or an A(M) motorway section of it) as its first road. Damage-only collisions are not in STATS19.
Is the A1 getting more dangerous?
These are counts, not rates. The data does not include how much traffic used the road each year, so a rise or fall can reflect traffic growth, roadworks, reporting changes (several police forces moved to the CRASH recording system) or real change. The yearly table above shows the recorded numbers without drawing that conclusion for you.
Why might a crash near the A1 be missing?
STATS19 first_road_class A (3) or A(M) (2) and first_road_number = 1, so the A1(M) sections are included; collisions where the road is only the second road are not included. Crashes on slip roads or local roads next to it can be recorded under another road.
Which year had the most recorded collisions on the A1?
2022, with 723 recorded collisions. The fewest were in 2025 (591). These are counts for 2021–2025, not rates, so a busier year on the road can record more without the road being less safe.
When do most recorded collisions on the A1 happen?
The busiest hour in the records is 16:00–16:59 (7.7% of collisions with a recorded time), the busiest day is Friday and the busiest month is June. The data holds no traffic volumes, so these peaks show when crashes were recorded, not when driving there is riskiest.
Which council area records the most collisions on the A1?
Islington, with 575 recorded collisions (23.8% of the total). Longer sections of road inside one council area naturally record more, so this is not a ranking of danger.
Can I download the A1 accident data?
Yes. The yearly counts, the counts by local authority and the mapped crash points can each be downloaded as CSV from the Source and limitations section of this page, with the source and licence written into the file.
Is this live?
No — this is historical data (2021–2025) published once a year. Live incidents and today's reports for the A1 are on the road's live page.
