When semi-trucks are involved in an accident with a car, the size discrepancy often results in severe injuries. Fortunately, our Dallas truck accident lawyers at Crowe Arnold & Majors, LLP know that one tool they have at their disposal is a Black Box-- otherwise known as an Event Data Recorder (EDR). An EDR is an electronic device that is installed in many commercial trucks. The EDR can withstand violent impacts, fires, submersion, and explosion. Moreover, it monitors the vehicle’s maintenance and the driver’s actions leading up to-- and during-- the crash. If your Dallas personal injury lawyer is able to collect the EDR, preserve it, and have it analyzed correctly, this may help provide substantial proof of the defendant’s liability for the accident.
