Do all commercial trucks have a black box?

Most modern 18-wheelers do. Federal regulations have increasingly mandated electronic logging and monitoring, so the vast majority of trucks on the road today have some form of EDR.

Is the black box data always accurate?

The data itself is highly reliable. However, it needs to be downloaded and interpreted by a trained expert who understands how to read the reports and present the information clearly in a legal setting.

What if the black box data doesn't help my case?

Even if the data shows the driver wasn't speeding, it is still valuable. It helps us understand exactly what happened and allows us to focus our investigation on other potential causes, like driver distraction or improper maintenance, that the EDR does not record.
