How Black Box Data Can Be Used in a Georgia Truck Accident Case

FAQs About Trucking Black Boxes as Evidence

How long is ECM data stored before it's overwritten? 

ECM data storage varies by manufacturer and type of event recorded. For example, hard braking data might be overwritten with the next hard braking event, while regular operation data can be stored for days or weeks before being replaced with new information. 

How much does it cost to download ECM data?  

If you need the Black Box data from a truck accident, you can expect to pay between $500 and $2,500, depending on the truck manufacturer and data complexity. Luckily, your attorney will usually advance you these costs as part of helping you with your case, recovering them later if your claim is successful.  

Can I request Black Box data without an attorney?  

Although you can request the ECM data yourself, trucking companies have been known to ignore requests from individuals without legal representation. On the other hand, an attorney can issue a spoliation letter that carries legal weight and consequences for non-compliance, guaranteeing you access to the crucial data.

Can I use ECM data in my Georgia court case?  

Yes, Georgia courts accept ECM data as evidence because it provides objective information about accident circumstances. However, to be admissible in court, the data must be authenticated by qualified experts. This is why having legal representation is important – your attorney will work with technical experts who can properly interpret and verify the Black Box data for your case. 

What if the trucking company that caused my accident claims they no longer have the ECM data? 

If they were notified to preserve the data prior to its deletion, this could constitute “spoliation of evidence” under Georgia law, likely leading the court to instruct the jury to presume the missing evidence was unfavorable to the trucking company, thereby strengthening your case. 

Working with The Millar Law Firm was an excellent experience for me. I truly can't say enough about how hard they work for their clients. Justin and Jennifer kept me consistently informed with updates throughout my case. Justin was always available to answer my questions and often checked in just to see how I was doing. They successfully settled my case, and I was very pleased with the outcome. If I ever need a law firm for this type of situation again, it will definitely be The Millar Law Firm.
