ELD Revocations Expose Shared Software Risk
NMFTA researchers say many registered ELDs may share underlying software, meaning individual FMCSA revocations may not remove the broader compliance and security risk.
The revocation list may not tell the whole story
FMCSA has revoked at least 79 electronic logging devices since January 2025, but researchers at the National Motor Freight Traffic Association say the bigger issue may sit below the brand names on the registered-device list.
Heavy Duty Trucking reported that multiple ELDs marketed under different names may share the same underlying software platforms. If one product is pulled from the market, related devices can remain available even when they rely on the same components.
Why shared software matters
ELD manufacturers self-certify that their devices meet federal technical standards. The registered list is not an independent cybersecurity certification, and NMFTA has been using reverse engineering and open-source intelligence to examine the hardware, firmware and software behind devices in the market.
The concern is that some product families may include more than 100 separate devices sold under different company names while sharing parts of the same software. NMFTA has shared its findings with FMCSA and is also examining where the devices are manufactured and supported.
What fleets should check now
The practical fleet risk is simple: a device can look compliant until it is not. If an ELD is revoked, carriers have limited time to replace it, retrain drivers and protect hours-of-service records before the device creates enforcement exposure.
Fleets should cross-check current devices against FMCSA's revoked list, ask vendors whether their units share software with products under review and keep replacement options warm. The safest posture is to treat ELD compliance as an ongoing vendor-risk check, not a one-time purchase decision.
