What is a truck's black box, and why is it important for my case?

A truck's black box, officially known as an Electronic Control Module (ECM) or Electronic Logging Device (ELD), is an onboard computer that records vital driving data leading up to a collision. Under Federal Motor Carrier Safety Administration (FMCSA) regulations, this device tracks speed, brake application, steering inputs, and hours of service. This data is critical because it can prove driver fatigue or speeding. Because trucking companies may legally overwrite this data after a certain period, Jeffrey S. Altman acts quickly to send formal preservation letters to secure this evidence for your claim at The Altman Law Firm.
