Fleet Accident Investigation and Scene Documentation

Fleet data is good at speed, braking events, location, and time. It is less good at the things that get argued about later: where each vehicle sat in the lane, what the driver could see past a parked trailer or a hill crest, whether a sign was blocked by brush, and how the load was sitting after impact. Those answers come from the physical scene and from the unit itself, and both change quickly once the roadway reopens and the vehicle moves to a tow yard.

Delator's field notes are written to sit next to the operator's data, not to replace it. Timestamps on photographs let a reviewer line up the scene record with telematics events. Measurements are tied to fixed reference points so that a reconstruction professional can use them later. Delator's personnel have accident reconstruction experience, which shapes what gets photographed and measured, but a documentation assignment does not include an opinion on who was at fault.

Data on the unit and why handling matters

Dash cameras overwrite, telematics vendors keep detailed data for limited periods, and a unit that goes back into service keeps recording over what it captured. Those retention details vary by vendor and by the operator's settings, so Delator does not guess at them. The investigator records the make and model of each device where visible, notes whether indicator lights were on, and reports it to the requesting party the same day so that the people responsible for the data can act.

Delator does not download engine control module data or pull footage from onboard devices. The operator or its vendor retrieves the data and Delator documents the physical side. Because Tennessee uses modified comparative fault, the allocation between drivers matters to every party, and a neutral scene record gives the carrier, counsel, and any retained expert the same starting point. The devices are photographed in place so that their presence is not in question later.
