J.S. Held experts in accident investigations, computer visualization, and accident reconstruction support the State of California in a $94 million suit.
JERICHO, N.Y., Feb. 20, 2025 /PRNewswire-PRWeb/ -- The state of California retained accident reconstruction experts from J.S. Held to assess a devastating crash involving an autonomous vehicle on a California highway. The vehicle collided with a center median attenuator at 70 miles per hour. The car then spun back into traffic, impacting another vehicle and killing the driver.
The vehicle manufacturer settled with the driver's estate pre-trial, but the estate pursued damages against the state of California and CalTrans, claiming the previously damaged crash attenuator should have been repaired sooner.
J.S. Held experts have reconstructed thousands of accidents involving vehicles of all types, including motorcycles, commercial and industrial equipment, personal transportation equipment (like bicycles and scooters), boats, planes, and trains.
By employing cutting-edge simulation and analytical techniques, the team gathers, analyzes, and interprets physical and digital evidence to deliver an accurate picture of how an accident happened. Engineers and visualization staff work together to create visual products that represent and communicate the findings of investigations and analysis in a clear, concise, and compelling manner.
Based on the outcome of the autonomous vehicle accident investigation, a unique trial demonstrative was created by a team of visualization specialists at J.S. Held. The J.S. Held accident reconstruction expert testified that the driver's inattentiveness, due to playing a video game while behind the wheel, contributed to the accident. The driver avoided a similar accident at the same location previously. The expert testified that even if the attenuator had been repaired, the vehicle would have likely been impacted by the following vehicles, and the outcome would have been similar. J.S. Held's detailed analysis and visualizations, coupled with the expert's testimony, helped acquit CalTrans, saving the state of California $94 million.
