The ‘black box’ could be a deal breaker in your trucking accident

On Behalf of | May 7, 2025 | Truck Accidents

A trucking accident can result in serious injuries, significant financial losses or even death. But amid all the chaos and confusion of this challenging time, the ‘black box’ may provide the clarity that you need.

Modern commercial vehicles are equipped with electronic systems that track pertinent information. In many Virginia accident cases, this digital evidence, if preserved in time, can be crucial in proving who was truly at fault.

What is a black box and why does it matter?

Since December 2017, the FMCSA has required most commercial truck drivers to use Electronic Logging Devices (ELDs) and other systems commonly known as the black box.

Together, the ELD, engine control modules (ECMs) and GPS tracking systems can reveal important details. For instance, an ELD is a federally approved tool that records a truck driver’s hours of service by syncing with the vehicle’s engine. It tracks when the engine is running, how far the truck has traveled and how long it’s been in use. The ECM stores diagnostic information about the vehicle and can detect mechanical issues with the engine. Meanwhile, GPS tracking systems can show the truck’s exact route and location at the time of the accident. This information can help confirm or challenge a driver’s account of what happened.

This can be pivotal evidence in determining whether driver error or company negligence played a role in the crash. In many cases, ELD records are some of the most objective, tamper-resistant evidence available.

Why it’s best to act fast when preserving evidence

The black box can hold valuable information after a trucking accident, but only for a limited time. By law, motor carriers are only required to retain ELD records for six months. Some data could even be lost or deleted if it’s not secured promptly. That’s why it’s important to act quickly if you’ve been involved in a crash with a commercial truck.

Speaking with a lawyer early on can help send a legal notice to preserve this digital evidence before it’s gone. Having that information can make a real difference in understanding what happened and how you can receive the compensation you deserve.
