In traffic law (criminal) and personal injury litigation, case outcomes often depend on the accurate application of physics, engineering principles, and human factors. Our services provide a rigorous scientific basis to challenge inaccuracies, reconstruct complex events, and deliver clear, credible testimony for judges, juries, and insurance providers.

Role and Responsibilities of the Expert Witness – Engineer

An Engineer Expert Witness (EEW) is a qualified professional who specializes in science, physics and engineering disciplines and provides specialized technical assistance to the judiciary, including judges, juries, and attorneys. Their role involves explaining and interpreting the application of scientific and engineering principles relevant to particular cases, especially within the context of applicable laws and regulations. EEWs are qualified to testify on a variety of topics such as traffic accident reconstruction, speed measurement devices, vehicle equipment, and traffic control systems. It is important to emphasize that all conclusions are based on empirical, evidence-supported data, rather than unreliable or unsubstantiated scientific claims.

Reasons to Engage an Expert in Accident Cases:

Traffic Accident Reconstruction:

We analyze the circumstances of collisions using scientific methods to determine the causes and contributing factors. Our reconstructions are essential for establishing liability, causation, and damages.

Black Box" Data Analysis: We examine  data from vehicle airbag control modules, providing detailed information such as pre-crash speed, brake status, throttle position, and change in velocity (delta-V).

Scene Documentation Analysis: We conduct thorough analyses of police reports, photographs, skid marks, scuff marks, and vehicle final positions.

Speed and Impact Velocity Calculations: Applying physics and engineering principles, we determine vehicle speeds, impact points, and time-to-collision estimates.

Kinematic and Injury Causation Analysis: We assess the forces involved in the collision and evaluate their relationship to the injuries claimed, determining biomechanical plausibility.

Visual Aids and Animations: We develop detailed diagrams and computer-generated animations to visually depict the sequence of events, supporting mediation, arbitration, or court proceedings.

Human Factors and Perception-Response Time Analysis

A driver’s actions must be evaluated within the context of human perception and response capabilities. We analyze whether the driver had adequate time to perceive hazards and respond appropriately.

Sight Distance and Line-of-Sight Analysis: Was the hazard visible early enough for a reasonable driver to detect and react?

PRT: Using established scientific data, we determine whether the driver's response fell within a reasonable timeframe for the given situation.

Emergency Response Evaluation: We provide analysis to support claims that a driver faced an unforeseen emergency situation not of their own making.
