Paul Tydeman

Paul Tydeman, one of our senior consultants, has been an accident investigator since 1990.

Prior to his retirement from the Metropolitan Police Service in May 2016 he was employed as the Senior Forensic Collision Investigator for the East London Serious Collision Investigation Unit.

Paul worked for an insurance company for 4 years, specialising in motor claims, before becoming a Police Officer in 1983. Following 6 years general police duties, he joined the Traffic Department in 1989. He began his training in collision investigation in 1990 and has been working in this field since that time. From 2001 until his retirement he was the Senior Forensic Collision Investigator for the north east London area, with responsibility for the review and quality assurance of all incidents attended by a team of 8 collision investigators. He has reviewed over 3000 collisions in this role. He was also responsible for the training and mentoring of all new collision investigators in that unit.

As a collision investigator he attended several hundred fatal and serious injury collisions, and has given evidence as an expert witness on numerous occasions in Civil, Criminal and Coroners Courts.

Until his retirement Paul was the lead for the Metropolitan Police Service for Incident Data Recorders and vehicle borne technology. He was involved in the development of incident data recorders for the MPS, working with manufacturers to develop the software and correct parameters for the device, and advising the Fleet Services engineering department. As part of this development he was involved in field testing, including crash testing; he is therefore familiar with the results produced by the devices. He was also responsible for the training of collision investigators, traffic supervisors, and other users of this technology.

During his service Paul attended the Metropolitan Police technical training school at Hendon Driving School where he qualified as a police class 1 car driver, a police motorcyclist, an advanced vehicle examiner, a fatal accident vehicle examiner, an advanced accident investigator and a level 3 tachograph examiner and calibrator.

He is the holder of a clean car and motorcycle licence, with LGV (Category C+E) and PCV licence (Category D+E) entitlements. In addition to these licences he has held a vocational licence for the Carriage of Dangerous Goods and Packages.
