Truck black box data can be among the most valuable evidence when a collision involving a commercial truck results in injury. This device records critical data about the truck, including in the moments leading up to a crash. Evidence of negligence can help support an injured person’s claim.
However, trucking companies have an incentive to keep this data private – and in some cases, they may try to destroy it. An experienced Georgia truck accident lawyer from Spiva Law Group can take steps to preserve this critical data.
What Is a Black Box in a Truck?
The black box in a commercial truck is an electronic device that records and stores data from the vehicle’s systems. This device is often called an engine control module (ECM). It works with the truck’s computer system to track how the vehicle operates before, during, and after certain events.
When a serious crash happens, the black box may provide a digital record of the truck’s activity, which can help show what was happening with the truck. Having this data means you don’t have to rely solely on witness statements, driver reports, or physical evidence from the crash scene.
What Information Does a Truck’s Black Box Provide About a Crash?
A truck’s black box provides several details that can help explain how a crash happened. It doesn’t replace physical evidence, but being able to review this data alongside the physical evidence and the driver’s account can provide insight into whether unsafe driving contributed to the collision.
Depending on the vehicle, the available data may include the following:
- The truck’s speed before impact
- Whether the driver applied the brakes and, if so, how hard
- Throttle position
- Sudden acceleration or deceleration
- Engine RPM
- Cruise control use
- Seat belt status
- Airbag deployment
- The truck’s direction of travel
- Fault codes or system warnings
- Hours of service or driving activity
How Can You Use Truck Black Box Data in a Georgia Truck Accident Claim?
Most personal injury claims are based on negligence (someone’s failure to abide by their duty to avoid causing harm), and black box data can be valuable in showing a truck driver’s or trucking company’s negligence before a collision. For example, this data may help you show that the truck driver was speeding or wasn’t braking in time. There may already be evidence or testimony supporting such a claim, but the black box data can be helpful in backing it up.
You can also use black box data to challenge an inaccurate version of events. If the trucking company or insurer claims the truck driver did nothing wrong, the black box data may tell a different story.
Can a Truck’s Black Box Data Be Lost or Deleted?
Black box data isn’t permanent. Some systems only store information for a limited time or record over older data after a certain period. Repairs, software updates, or changes to the truck’s electronic systems can also affect stored information. In some circumstances, trucking companies may deliberately overwrite or delete data. For all of these reasons, it’s important to act quickly after a truck accident to make sure the black box data remains available.
What If the Trucking Company Refuses to Share Black Box Data?
If a trucking company believes the black box data may implicate them or their driver in a crash, they may resist turning over the data to an injured person’s attorney. The company may claim that the data is unavailable or irrelevant, or that it isn’t obligated to disclose it.
However, you’re not without options. Your attorney at Spiva Law Group can request black box data through the legal process if it relates to the crash. If a trucking company fails to preserve relevant data after proper notice, that refusal may become an important issue in the case.
Is Black Box Digital Evidence from a Truck Admissible in Georgia?
Black box data may be admissible in court if it’s relevant, reliable, and obtained through the proper channels. However, it may need to be authenticated before you can use it in court. This means you’ll need to show where it came from, how it was preserved, and that it accurately reflects the truck’s activity.
How Can a Georgia Truck Accident Lawyer Help You Obtain Black Box Data?
Trucking companies often have substantial legal and financial power on their side. But this doesn’t mean they can bully injured people to protect their own interests. That’s why there’s a legal process in place that makes it possible to request black box data, and an experienced Georgia truck accident lawyer has likely been through this process before.
Your attorney at Spiva Law Group can start by sending a preservation of evidence letter to the trucking company, driver, insurer, or any other parties that may have control over the truck or its records. The letter puts them on notice that they shouldn’t destroy, alter, or overwrite the black box data.
We can also request the data during the claims process or through discovery if it becomes necessary to file a truck accident lawsuit. In some cases, they may also work with investigators or technical professionals who can download and review the information.
