After a truck accident where negligence is suspected on the part of the truck driver or the trucking company, it is important to contact an attorney as soon as possible. If the victim of a truck crash wishes to pursue a personal injury lawsuit, lawyers can obtain data from a truck’s Electronic Control Module (ECM) or “black box”. These devices can provide important information regarding the truck’s operation that could prove useful in a lawsuit when they reveal problems such a truck driver fatigue or negligence by the trucking company. Most ECMs record data for 30 days but after that begin to write over old data, making it necessary to act quickly in the aftermath or a trucking accident. Read more about ECMs and trucking accidents.
