Key Takeaways
- In 2021, motorcyclists were 28 times more likely than passenger car occupants to die in a motor vehicle crash per registered vehicle.
- From 2017-2021, the rate of motorcycle crash deaths per 100,000 registered vehicles was 23.95, compared to 1.28 for passenger cars.
- Motorcycles accounted for 14% of all traffic fatalities in 2021 while representing only 3% of registered vehicles.
- Motorcyclists accounted for 5,932 deaths in 2021, 14% of all traffic fatalities, vs. cars dominant but lower per vehicle.
- Fatality rate per 100 million VMT: motorcycles 24.81 vs. cars 1.34 in 2020.
- 80% of motorcycle fatalities involve other vehicles, mostly cars turning left.
- In 2021, 82% of motorcycle crash victims had serious injuries vs. 45% for car occupants.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
