Car Crash Causes Statistics

Fatal crashes are shaped by human choices and harsh conditions, with speeding contributing to 27% of US fatal crashes and alcohol impairment to 30% in the latest reporting. Yet the page also tracks the “other half” of the risk with seat belts, distraction, lane mistakes, and intersection crashes that turn ordinary drives into preventable outcomes.

Car Crash Causes breaks down what actually turns a normal drive into a fatal one, and the patterns are sharper than many people expect. In the United States, speeding is tied to 27% of fatal motor vehicle crashes, while alcohol impairment contributes to 30% and distracted driving to 9%. Then the data flips from driver behavior to street design and conditions, with intersections and lane related mistakes forming a surprisingly large part of the risk.

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
ChatGPTClaudeGeminiPerplexity

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
ChatGPTClaudeGeminiPerplexity

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
ChatGPTClaudeGeminiPerplexity

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
