Seat belts prevent about 50% of crash deaths overall, and in the United States alone NHTSA estimates they have saved 374,276 lives from 1975 through mid 2023. Yet the numbers also show what happens when people go unbelted, from tens of billions in annual medical costs to higher injury and insurance claims. This post walks through the key findings from NHTSA, IIHS, CDC, and WHO so you can see exactly where the impact shows up and why enforcement and usage matter.

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
