The Federal Motor Carrier Safety Administration revoked five electronic logging devices from its list of approved products on August 7, citing failure to meet the technical standards set out in Title 49 of the Code of Federal Regulations. The affected devices, which included the Moonlight ELD and the HGRS ELD, no longer satisfy the minimum requirements the agency uses to certify hours of service recording equipment.
Motor carriers running the revoked units have 60 days from the notice to switch to a compliant device. FMCSA said drivers who continue relying on the revoked ELDs past the October 6 deadline could be placed out of service during roadside inspections. In the interim, the agency has instructed affected carriers to fall back on paper logs or approved logging software to document hours of service.
This is part of a broader compliance push. FMCSA has revoked 55 ELDs so far in 2026, more than in any prior year of the registry's operation, as the agency works through complaints and internal audits of device makers. Roughly 953 devices remain on the approved list nationwide.
For fleet managers, the revocation list has become something to check regularly rather than a one time compliance task. A device that passed certification review a year ago can lose that status with little public notice, and the burden of tracking the change falls on the carrier, not the vendor.
