This article appears to have some political bent to it based on comments about immigration.

I was made curious about the possibility of an "intentional backdoor" in ELD (Electronic Logging Devices) that allowed truckers to misreport their hours.

I was not able to find results to directly confirm or deny that this was true, but it certainly seems like these recently-mandated ELDs come with security concerns: https://www.ndss-symposium.org/wp-content/uploads/vehiclesec...

It is odd that they mention several plausible reasons for the problems they see but really seem to single out immigration as the key problem. That seems backwards to me. If safety regulations are no longer being enforced as they claim, where the drivers were born is irrelevant.
