Automotive Forensic Technicians
Experts in forensic work, our Automotive Forensic Technicians determine if a mechanical failure or defect could have contributed to an accident or collision. They analyze vehicles alleged to have been stolen to determine if security devices were compromised and if any prior cosmetic or mechanical deficiencies existed at the time of the alleged loss.
From electronic engine management systems to brake systems, our technicians understand the complexities of the modern automobile and the failures and malfunctions potentially contributing to a fire or collision loss. These Auto Forensic Technicians can team up with our Accredited Accident Reconstructionists to provide a multi-faceted analysis of a given loss, such as determining if an alleged collision occurred and if a mechanical failure caused the collision.
Our team of technicians features experts with industry-specific qualifications such as Certified Vehicle Fire Investigators, Certified Fire and Explosion Investigators, ASE Master Automotive Technicians, and Certified Forensic Locksmiths.
