Five electronic logging devices were moved to FMCSA's revoked list on August 6; affected carriers must transition now and install a compliant device by October 6, 2026.
What FMCSA announced
On August 6, 2026, the Federal Motor Carrier Safety Administration removed five electronic logging devices from its registered list after the providers failed to meet minimum technical requirements in 49 CFR Appendix A to Subpart B of Part 395. The affected devices are MOONLIGHT ELD (identifier MRS255), HGRS ELD (HRS169), HIGHEST ELD (HIG385), TRUCKFORD ELD (TRS263), and Sparkle ELD (SPARK6).
What affected carriers must do now
FMCSA instructed carriers using the revoked devices to discontinue their use and revert to paper logs or logging software for required hours-of-service records. Carriers should confirm which units and drivers are affected, communicate the temporary logging process, preserve accessible records, and select a replacement from FMCSA's current Registered Devices list rather than relying only on a vendor's marketing materials.
October 6 is the replacement deadline
FMCSA gave motor carriers up to 60 days to replace the five devices with a compliant ELD, setting October 6, 2026 as the deadline. Before that date, safety officials are encouraged to review paper logs, logging software, or the device display as a backup instead of citing specified no-record-of-duty-status or unregistered-ELD violations solely because one of these devices is in use.
Enforcement changes after the deadline
Beginning October 6, a carrier that continues using one of the listed devices will be considered to be operating without an ELD. FMCSA's bulletin says safety officials should cite 49 CFR 395.8(a)(1) and place the driver out of service under the Commercial Vehicle Safety Alliance criteria. That makes a late replacement an operational risk, not merely a purchasing delay.
A practical fleet transition checklist
Inventory device names, model numbers, and ELD identifiers across tractors and contractor units. Notify dispatchers and drivers in writing, distribute instructions for compliant temporary records, confirm data-export and retention needs, choose a registered replacement, schedule installation and training, and test the transfer workflow before the deadline. Keep documentation showing when affected hardware or software was removed and the replacement activated.
What drivers should verify before dispatch
Drivers should know which logging method the carrier requires during the transition, how to reconstruct recent duty status when necessary, where supporting documents are stored, and whom to contact if an inspector or device raises a question. Do not improvise or alter records. Ask the carrier for written instructions and confirm the replacement ELD appears on FMCSA's registered list before relying on it.
Could a device return to the registered list?
FMCSA states that a provider may correct the identified deficiencies and have a device restored to the registered list. The agency nevertheless encourages carriers to act now so they are not exposed if a provider does not complete corrective work in time. Check the live FMCSA lists before making a final procurement or compliance decision because device status can change.
