Truck Black Box (EDR) Data: Why It Matters in Your Case
Many commercial trucks record data that can show what the vehicle was doing seconds before impact.
What the Data Can Show
- Vehicle speed
- Brake application and timing
- Throttle position
- Hard-braking events
- Engine and fault codes
ELD vs. EDR
An ELD tracks driver hours and location. An event data recorder captures crash-related vehicle data. Both can be valuable.
The Risk of Lost Data
Information may be overwritten or erased after repairs or routine use. A preservation letter sent promptly demands that the carrier keep the data and the device.
Using the Data
Experts download and interpret the data to reconstruct the crash and test the driver's account.
