Why a Pittsburgh Truck Accident Lawyer Is Key to Preserving Electronic Data
By Ben Gobel on July 15, 2026
If you were hurt in a collision involving a semi or commercial truck, one of the most important things you can do is act fast to preserve the electronic data connected to that truck. This data can show exactly what happened before the crash, and without it, your claim could be much harder to prove. A truck accident lawyer in Pittsburgh PA can step in quickly and take the legal steps needed to make sure that evidence is not lost.
What Electronic Data Exists After a Truck Accident?
Modern commercial trucks are rolling computers. They generate and store large amounts of electronic data every time they are on the road. If you or someone you love was hurt in a crash, this data may hold the key to understanding why it happened.
The Electronic Logging Device (ELD)
Federal law requires most commercial trucks to use an Electronic Logging Device, or ELD. These devices record hours of service, meaning they track how long a driver has been behind the wheel. If a driver was fatigued or had exceeded legal driving limits, the ELD could show that.
The Event Data Recorder (Black Box)
Many large trucks are equipped with an Event Data Recorder, often called a black box. Similar to what you find on an airplane, this device captures data in the seconds before a crash, including:
- Vehicle speed
- Brake application and timing
- Engine throttle position
- Steering input
- Whether the driver was wearing a seat belt
This information could be critical in proving that a driver was speeding or failed to brake in time.
GPS and Telematics Data
Many trucking companies use GPS tracking and telematics systems to monitor their fleets in real time. This data could show the truck’s exact route, speed at specific locations, and any unexpected stops or hard braking events prior to impact.
Dash Camera Footage
Some trucks are equipped with dash cameras facing forward or inward. If footage exists, it may capture the moments leading up to the crash directly.
Why This Data Disappears So Quickly
Here is the difficult reality: trucking companies are not required to hold onto most of this data indefinitely. In fact, some systems automatically overwrite data within 30 days. Others may be erased even sooner if the truck returns to service.
Beyond automatic overwriting, there is also the risk that a trucking company or its insurance carrier will destroy data once they realize a claim is likely. This is sometimes called spoliation of evidence, and while courts can penalize it, the damage may already be done if the data is gone before anyone asks for it.
This is not about assuming bad faith in every case. But when large sums of money are at stake, trucking companies and their insurers move quickly to protect themselves. You should too.

At Ogg, Murphy & Perkosky, P.C., our attorneys have been representing injured people in the Pittsburgh area since 1981. We understand how trucking companies operate and what it takes to preserve the evidence that matters most.
When you call us after a truck accident, one of the first things we may do is send a legal preservation letter, sometimes called a spoliation letter, to the trucking company and its insurer. This letter puts them on formal notice that they are legally required to hold onto all relevant data and records connected to the crash.
What a Preservation Letter May Cover
- All ELD and hours-of-service records
- Black box and event data recorder files
- GPS tracking and dispatch records
- Driver qualification files and training records
- Vehicle maintenance and inspection logs
- Dash camera footage
- Communication records between driver and dispatch
Sending this letter early could make the difference between having the evidence you need and having nothing to work with.

Frequently Asked Questions About Truck Accidents
What electronic data can be recovered after a truck accident in Pennsylvania?
After a crash, it may be possible to recover data from the truck’s event data recorder, electronic logging device, GPS system, dash cameras, and telematics systems. The availability of this data depends on how quickly steps are taken to preserve it and whether the trucking company has already overwritten or disposed of records.
How long do trucking companies have to keep black box data in Pennsylvania?
Federal regulations set minimum retention periods for some records, but not all electronic data is covered for the same length of time. Some event data recorders overwrite their files automatically within 30 days or sooner. This is one reason why reaching out to a lawyer quickly after a truck accident is so important.
Why do I need a lawyer to preserve evidence after a truck accident in Pittsburgh?
An attorney can send a formal preservation letter to the trucking company and its insurer that creates a legal obligation to hold onto data and documents. Without this letter, a company may have no legal duty to save records that would otherwise be deleted in the normal course of business. Acting quickly gives your case the best possible foundation.
What happens if a trucking company destroys data before my claim?
If a trucking company destroys evidence after being put on notice of a potential claim, a court may impose sanctions or allow the jury to draw a negative inference, meaning they could assume the destroyed evidence would have been harmful to the trucking company’s case. However, this is not a guaranteed outcome, and it is always better to secure the data before it disappears.
