Yes. In Connecticut, black box data can be used as evidence if it is properly obtained and authenticated. The term “black box” is commonly used to describe onboard electronic systems, such as an event data recorder (EDR), engine control module (ECM), or other vehicle data systems. These systems may record information about the truck’s operation immediately before and during a crash, including vehicle speed, throttle position, engine RPM, brake application, and other performance data, depending on the vehicle and equipment. An experienced truck accident lawyer can take steps to preserve and obtain this electronic data through the legal process and work with an accident reconstruction expert to analyze what it reveals about the crash.
