Yes. Most commercial trucks are equipped with an event data recorder—often called a "black box"—that records valuable information before, during, and after a crash.
Depending on the truck, this data may include:
- Vehicle speed
- Braking activity
- Throttle position
- Steering inputs
- Engine performance
- Seat belt usage
- Sudden acceleration or deceleration
This information can help investigators determine exactly what happened in the moments leading up to a collision. It can also confirm or contradict statements made by the driver or trucking company.
