Almost every passenger vehicle on the road is equipped with an Event Data Recorder (EDR), sometimes called a “black box.” These systems can capture critical, crash-related data that can be invaluable in determining what happened before and during a collision. EDR data plays a key role in determining speed, driver actions, and impact forces, making it a crucial forensic tool. I specialize in retrieving, interpreting, and analyzing EDR data to provide clear, court-admissible insights.
You can see if your vehicles are supported HERE, or contact me to see what data they may have recorded.

Many commercial motor vehicles (CMVs), such as semi-trucks, large buses, and delivery vehicles, can record crash related data in their engine control modules and, increasingly, in their collision mitigation systems. Many CMVs also have dash cameras and/or telematics systems that can capture a wealth of information. This data can be retrieved and analyzed to accurately reconstruct the events of an accident.
These systems provide data on speed, braking, throttle and/or accelerator pedal position, and cruise control status. They can also record diagnostic data that may reveal potential mechanical failures or malfunctions, such as issues with braking systems or engine performance.
CMV brake systems can be compromised by improper or neglected maintenance. A thorough inspection can identify the potential for poor brake performance.

Scene evidence is crucial in traffic crash investigations, as it provides the foundational information needed to reconstruct the events leading to a collision. Physical evidence such as tire marks, vehicle position, and debris, and damage patterns can reveal vital insights into the dynamics of a crash, including vehicle speeds, angles of impact, driver actions, and vehicle position at the point of impact. Other crucial elements of the crash can also be documented, such as obstructions to sight lines, where impact occurred, and improper signage or paving defects.
Scene investigation is often the most time sensitive aspect of crash reconstruction making it urgent, before valuable evidence is lost.

Aerial photography and mapping provide a comprehensive perspective of the crash site. We use RTK corrected drones and GNSS receivers to create highly accurate orthographic images, maps, and 3D point clouds of the scene. These tools capture detailed visual data that can reveal critical information about a scene and allow for a comprehensive analysis traditional methods may miss.

A complete post-crash vehicle inspection is essential for uncovering vital evidence and sheds light on the causes and circumstances of a collision. By assessing the damage, vehicle characteristics, mechanical condition, and safety features, we can identify inconsistencies, validate claims, and reveal details that may significantly influence the outcome of a case. Vehicles are documented with photographs and in most cases a 3D scan. This allows for accurate measurements of the car to be taken long after it’s gone.

Case studies
"A farmer was driving a large tractor along a two-lane road when an oncoming driver struck his left rear wheel and was killed. The farmer was intoxicated and the police report indicated he had crossed the center line striking the other car. From ground level the tire marks were confusing and unclear. We took clear aerial photographs that clearly showed the other driver had crossed the center line and struck the tractor. "
Case studies
"About 20 minutes before sunrise, a driver turned left in front of a vehicle approaching in the opposite direction. The turning driver claimed the approaching vehicle had no headlights on or she would have seen it. Another expert examined the headlights and opined they were not on at impact. His findings directly contradicted the sources he cited to justify them. In fact, his source gave an example exactly like the crash in question and stated an investigator “would be foolish” to reach the same conclusions as the opposing expert. He did not testify at trial and a jury found the turning driver 100% liable for the collision. "
Case studies
"A driver turned left as her green signal turned yellow. She turned into the path of an oncoming motorcyclist that struck the side of her car. Video analysis showed the motorcyclist traveling twice the posted speed limit as he approached the intersection. A jury found the motorcyclist 100% liable for the collision"
Case studies
"A driver was fleeing from the police and was injured when he struck a guard rail end terminal and overturned. He claimed the end terminal malfunctioned causing his injuries and that he was simply driving home and unaware of the police. A download of his vehicle showed he was traveling in excess of 100 mph at impact, effectively ending the case. n"
