Vehicle downloads provide investigators with key pieces of information for vehicle claims to help establish the severity of a collision, driver behaviour, and whether or not the claimants are being truthful. Downloads from consumer vehicles and commercial heavy-vehicles can help answer these questions. We will cover data contained in typical “black-box” downloads (speed, braking, belting, occupancy, collision severity, etc.), additional data found in infotainment system downloads (GPS, text, data, bluetooth, vehicle behaviour, etc.), and data found in commercial heavy-vehicle downloads (hard braking events, speed, gear, cruise control, etc.). We will provide examples of real data downloads from actual claims and how the data was used to answer our client’s relevant questions.
