Unthinkable: Accident Reconstruction With Ben Railsback

Accident Reconstruction with Ben Railsback

In this episode of Unthinkable, personal injury attorney Kyle Bachus sits down with Ben Railsback, a professional engineer and expert accident reconstructionist.

Railsback breaks down how science and engineering combine to uncover the truth behind crashes. From laser scanning sites and inspecting vehicles to analyzing “black box” data from modern cars, his work provides critical clarity that goes beyond police reports. This episode highlights the importance of precise evidence collection, the role of technology in reconstructing crashes, and how understanding the physics and timing of events shapes legal outcomes.

Key Insights:

• What Is Accident Reconstruction?: Railsback uses physics, engineering principles, and site inspections to piece together how crashes occur. 
• Engineering Meets Investigation: His technical expertise complements and often corrects police findings focused on criminal liability. 
• Evidence Fades Quickly: Tire marks, debris, and 911 calls must be documented swiftly to maintain accuracy. 
• Laser Scanning for Precision: 3D laser scanners create millimeter-accurate digital models of crash scenes, vital for analysis. 
• Black Box Data Unlocks Secrets: Modern vehicles store pre-crash data like speed and brake status—crucial for understanding driver actions. 
• Simulating What-Ifs: Crash reconstruction software models alternate scenarios to assess preventability and liability. 
• Video Evidence Grows in Importance: Dash cams and home security footage provide visual proof and can be precisely measured using optical tracking. 
• Accounting for Human Reaction Time: Railsback factors in perception-reaction delays, recognizing mental processes that can’t be recorded electronically. 

FAQ – Accident Reconstruction In Legal Cases

What Does An Accident Reconstructionist Do?

They analyze physical evidence, vehicle damage, and crash data to recreate events leading to a collision.

How Important Is Black Box Data?

Very—it records key information seconds before impact, offering objective insights into vehicle speed and driver inputs.

Why Use 3D Laser Scanning?

It captures crash scenes with extreme precision, allowing for detailed digital models used in court.

How Quickly Should Crash Evidence Be Collected?

Immediately—tire marks and debris can disappear quickly, impacting the accuracy of the reconstruction.

Can Video Footage Affect A Case?

Yes. Dash cam and security videos provide clear visual evidence and can validate or challenge witness statements.

What Is Perception-Reaction Time?

It’s the time a driver needs to see a hazard and react. Reconstructionists factor this into crash analyses to assess preventability.
