On roads posted 50 mph or more, head-on motorcycle crashes kill about one rider in four

Motorcycling crashes, 2021–2026 (2026 so far). Found in 2021–2023 (23% vs 4.5%); held in 2024–2026 (22% vs 3.2%).

Head-on crashes are a small share of motorcycle crashes; on fast two-lane roads they include a car or a rider over the centre line in a bend.

The share is within crashes: with no counts of how many people walk, ride or drive where, it can't say how likely a crash is for anyone.

A scan of the crash records found it in the earlier years, among thousands of patterns tested with a false-discovery control, and it held in the later years, which the scan never saw. A person then read it and checked it isn't an artefact of how crashes are recorded. The numbers above are recomputed from the data each time the site is rebuilt. All findings and the method

• When a motorcycle crashes alone, hitting a fixed object is about three times as deadly
• Solo motorcycle crashes in bends happen going downhill nearly twice as often as going uphill
• People hit on foot in the dark with no street lights are killed about four times as often
• A crash with a person on foot on a freeway kills them more than a third of the time
