A black box is also known as an Event Data Recorder (EDR), which can be used to give vital information regarding an accident that may have no current evidence.
The device records information regarding the truck driver’s actions such as speed, length of driving, braking, rate of acceleration, idle time, if a seatbelt was being used, if an airbag was deployed, etc.
If violations are discovered using the black box’s information, the truck driver could be proven liable. This information is much easier to obtain with an attorney representing your claim.
