Delator Claims Division/Accident Reconstruction
Accident Reconstruction Services

The Physics Behind The Collision, Documented By Licensed Investigators.

Delator Claims Division provides full-scope accident reconstruction across Tennessee — from scene measurements and vehicle inspection to black box data extraction, speed and reaction-time analysis, and expert courtroom testimony. Every reconstruction is built on a licensed private investigator foundation, not outsourced to an unaccountable third party.

Tennessee Context

Why Accident Reconstruction Matters in Tennessee

Tennessee's modified comparative fault rule means that liability in a serious motor vehicle accident is rarely a simple question — it's a percentage, and that percentage can determine whether a claim is paid in full, reduced, or barred entirely. When fault is contested, the physical evidence of the crash itself — speed, braking, point of impact, sequence of events — often matters more than any witness account. That evidence is also the most perishable part of the case: skid marks fade, vehicles are repaired or scrapped, and event data recorders can be overwritten or lost once a vehicle changes hands.

Tennessee's interstate corridors, from I-40 and I-24 through Nashville and Chattanooga to I-65 and I-75 running north-south, carry some of the heaviest commercial and passenger vehicle traffic in the Southeast. Serious and fatal collisions along these corridors, and on the state's rural two-lane highways, regularly generate high-exposure claims and litigation where a scientifically defensible accident reconstruction is the deciding factor between a contested verdict and a resolved claim. Insurance carriers, defense counsel, and plaintiff's attorneys across Tennessee increasingly rely on independent, licensed accident reconstruction to establish exactly what happened before memories fade and evidence disappears.

Our Reconstruction Methodology

A Complete, Evidence-Based Reconstruction Process

Every Delator accident reconstruction follows the same disciplined, six-part methodology, from the first hour on scene through final expert testimony.

01
Examine the Scene
We measure skid marks and tire scrub, document final vehicle resting positions, and map the full debris field — using tools including 3D laser scanners to capture the scene with survey-grade accuracy before it changes.
02
Inspect Vehicles
Detailed analysis of crush damage and deformation patterns, paint transfer evidence between vehicles, and safety restraint condition, including seatbelt stretching and webbing marks.
03
Download Electronic Data
Extraction of pre-crash data from vehicle Event Data Recorders (EDRs, commonly called "black boxes"), including speed, braking input, throttle position, and seatbelt status in the seconds before impact.
04
Calculate Physics Parameters
Application of energy, momentum, and time-distance analysis to estimate pre-impact vehicle speeds, closing velocities, and driver perception-reaction time based on the physical evidence collected.
05
Test Theories
Development of computer simulations and 3D animations to visualize and test competing theories of the collision sequence, built for use in legal proceedings and insurance claim review.
06
Provide Expert Testimony
Clear, technically grounded explanation of findings and conclusions in depositions, mediations, and court trials, translating complex physics into terms a judge or jury can follow.
Licensed Investigators, Not Just Technical Consultants

Reconstruction Built On A Licensed Investigative Foundation

01
Licensed Under Tennessee Law
Delator's accident reconstruction work is performed under the same licensed Tennessee private investigator standard that governs every DCD deployment — not handed off to an unlicensed technical consultant with no accountability to a state licensing board.
02
Trained Evidence Handlers From The First Call
Because the same organization that documents the scene can also reconstruct it, evidence is collected from the very first deployment with reconstruction-grade rigor — not gathered casually and reconstructed later from incomplete photos.
03
Courtroom-Ready Credibility
Licensed investigator status, combined with rigorous technical methodology, gives our reconstruction findings the foundation they need to withstand cross-examination in deposition or trial.
04
Neutral, Methodology-Driven Conclusions
Our findings follow the physical evidence and established reconstruction science — not the preferences of whichever party retained us. That neutrality is what makes the analysis useful to carriers, plaintiffs, and defense counsel alike.
Access To Specialized Expertise

One Call Reaches Delator Group's Full Specialist Network

Not every collision looks the same, and Delator Claims Division can call on investigators from across the broader Delator Group network with focused experience in specific accident types.

Commercial & Heavy Truck Dynamics
Specialized experience with tractor-trailer braking dynamics, load shift, jackknife sequences, and underride collisions specific to commercial motor vehicles.
Motorcycle Collision Analysis
Reconstruction approaches tailored to two-wheeled vehicle dynamics, rider trajectory, and the distinct evidence patterns motorcycle collisions produce.
Pedestrian & Bicycle Incidents
Focused analysis of vehicle-pedestrian and vehicle-bicycle collisions, including impact dynamics and throw-distance calculations specific to vulnerable road users.
Commercial Fleet Telematics & ELD Data
Experience working with fleet telematics and electronic logging device data alongside traditional EDR downloads for commercial vehicle claims.
Low-Speed & Parking Lot Incidents
Specialized approaches for low-speed impact analysis, where standard high-speed reconstruction methods often need to be adapted.
Multi-Vehicle & Chain-Reaction Collisions
Investigators experienced in untangling complex, multi-party collision sequences involving three or more vehicles.

Reconstruction-Grade Scene Work, Anywhere In Tennessee

Accident reconstruction lives or dies on how quickly the scene is preserved. Skid marks fade within days, debris is cleared from the roadway within hours, and a vehicle can be repaired or scrapped before anyone thinks to request an EDR download. Delator Claims Division runs its accident reconstruction work on the same statewide infrastructure that powers every DCD deployment — Delator Field Services' existing network across all 95 Tennessee counties — so a reconstruction-grade scene examination can begin quickly, whether the collision happened on a Nashville interstate or a two-lane county road in rural West Tennessee.

That statewide reach means carriers, attorneys, and self-insured fleets don't have to coordinate a patchwork of regional reconstruction consultants for cases spread across the state. One call reaches a licensed, statewide reconstruction capability, backed by the same no-subcontracting standard that governs every part of Delator Group.

Scope Of Work
Delator's accident reconstruction team provides scientific and technical analysis — vehicle speeds, causation mechanics, and sequence of events — based on physical evidence and applied physics. We do not determine legal fault or liability; that determination remains with the court, jury, or parties involved, informed by our technical findings.
Frequently Asked Questions

Accident Reconstruction, Explained

Our reconstructions follow established, peer-recognized methodology and are prepared with courtroom use in mind. Ultimate admissibility is determined by the court under the applicable rules of evidence and expert qualification standards.
Most modern passenger vehicles and many commercial vehicles support EDR data extraction. Availability and depth of data vary by make, model, and year; our investigators can advise on what's recoverable for a specific vehicle.
Yes. Commercial vehicle dynamics differ significantly from passenger vehicles, and we draw on investigators with focused experience in heavy truck braking, load dynamics, and telematics data.
Accident reconstruction deployments follow the same statewide dispatch network as our documentation services, with rapid response available anywhere in Tennessee. Scene-critical evidence like skid marks and debris fields should be captured as early as possible.
No. We provide the technical and scientific findings — speed, sequence of events, causation mechanics — that inform a fault determination. The legal conclusion of fault itself is made by the court, jury, or negotiating parties.
