Motorcycle deaths hit 5,932 in 2021, the highest level since 1975, yet the leading causes are often avoidable and surprisingly specific. One 56% figure from a 2020 IIHS study points to other drivers failing to see motorcyclists, while helmet use and intersection behavior can shift outcomes dramatically. As you look through the crash breakdowns, you will see how speed, left turns, rider experience, and roadway conditions collide in ways that do not show up in everyday driving assumptions.
Key Takeaways

Injuries Interpretation

How We Rate Confidence
Models
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.
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
Directional
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
Verified
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
