When working through an automotive accident claim or preparing for litigation, having fast, reliable technical reference points matters. Peter R. Thom & Associates offers a free suite of accident reconstruction calculators on our website, giving attorneys, insurance adjusters, and claims professionals a starting point for common reconstruction calculations, at no cost and with no consultation required.
What our TechRef Accident Reconstruction Calculator Covers:
Our Technical Reference Accident Reconstruction Calculators address six core formulas used in automotive forensic analysis:
Speed from Skids: Estimates minimum pre-braking vehicle speed using skid mark length and the road surface's coefficient of friction.
Skid Distance from Speed: Estimates stopping distance from a known speed under maximum braking force.
Perception and Reaction Distance: Estimates how far a vehicle travels during the driver's perception and reaction window, typically between 1 and 1.5 seconds, before any braking begins.
Distance Traveled at Speed: Identifies where a vehicle was located at set time intervals, useful for placing a car 1 to 5 seconds before or after a given point.
Acceleration: Time to Speed: Estimates how long it takes a vehicle to reach a target speed from a defined acceleration rate.
Acceleration: Distance to Speed: Estimates the distance required to reach a given speed under a predetermined acceleration level.

Who These Tools Are For
These calculators are built for professionals working on automotive accident cases: insurance adjusters at carriers, as well as personal injury attorneys preparing for deposition, trial, or settlement. If you need a ballpark figure to assess a claim or test a theory before investing in a full reconstruction, these tools give you a grounded, engineering-based estimate quickly.
A Starting Point, Not a Replacement
These tools are designed to produce estimated ranges, not definitive answers. Real-world accident reconstruction involves variables that no standalone calculator can fully account for: road geometry, vehicle condition, driver behavior, and physical evidence from the scene. When a case requires defensible analysis for court, expert witness testimony, or formal reporting, a certified accident reconstructionist needs to be involved.
Our engineering team at Peter R. Thom & Associates has provided expert consultation and accident reconstruction services nationwide for over 35 years. We work across automotive forensics, failure analysis, skidmark and steering analysis, highway and roadway design, and biomechanical review.
Access the Calculators
The calculators are available free on our website. Use them as a reference tool, then reach out when your case calls for a deeper analysis.
