Telematics, which records data on vehicle behavior, is used now mainly for underwriting, but the technology can also provide a treasure trove of information for claims adjusters, one vendor suggests. Auto insurance claims adjusters could potentially use telematics to determine how many passengers were in a vehicle that was involved in a collision and whether those passengers were wearing seatbelts, suggested Nino Tarantino, North American chief executive officer of Octo Telematics, in a recent interview. Telematics refers to technology that records data such as speed, location and driving behavior. It has traditionally been used by commercial fleet managers - for applications including vehicle diagnostics and tracking where vehicles were driven and when.
