Are EDR Devices Undoubtedly Helpful in the Reconstruction of a Road Traffic Accident?

All over the world, the vehicles introduced now into the market are usually provided with EDRs (Event Data Recorders), intended to measure and record the parameters that characterise the vehicle motion in the pre-, during-, and post-accident phases. The EDRs are to facilitate the description and rec...
