Crash Energy & Speed Analysis

NHTSA Stiffness Coefficient Analysis Tool

Designed by Driven Evidence - Copyright 2026 | US Patent Pending

Fraud Detection & Defense Tool: This calculator uses NHTSA crash stiffness coefficients to reverse-engineer impact speed from vehicle damage. By comparing calculated speed with claimed speed and injury patterns, attorneys can identify inconsistencies suggesting fraud, exaggeration, or disputed liability. Based on peer-reviewed crash reconstruction methodologies.
