Truck Crashes Leave Digital Clues — If You Know Where to Look
Every commercial truck is equipped with a black box — an electronic control module (ECM) or electronic logging device (ELD) that records key data. This data could make or break your case.
What’s Inside the Black Box?
These devices track:
Speed and braking
Engine diagnostics
Hours driven without rest
GPS location at time of crash
Why Trucking Companies Try to Hide It
They know this data can prove:
The driver was speeding
The driver didn’t take required breaks
The truck wasn’t maintained properly
If that data disappears, it’s your word against theirs. That’s why our firm acts immediately.
Rodriguez Law Firm Sends Immediate Preservation Letters
We make sure the evidence is locked down before the company “accidentally” deletes it. If they still erase it, we push for sanctions in court.
Real Result:
In one case, we discovered that a trucker had falsified his driving logs. Using ELD data, we proved he was on the road 14 hours without rest. Our client received a $2 million settlement.
Don’t Let Crucial Evidence Vanish
Every hour that passes puts your case at risk.
