When an ELD Malfunctions
An ELD failure doesn’t stop hours-of-service rules from applying. Under 49 CFR 395.34, the driver must:
- Note the malfunction and give the motor carrier written notice within 24 hours.
- Reconstruct the record of duty status for the current 24-hour period and the previous 7 consecutive days on paper graph-grid logs, unless those records are already in hand or can be retrieved from the ELD.
- Keep logging on paper until the ELD is serviced and back in compliance.
The motor carrier must correct the malfunction within 8 days of discovering it or of the driver’s notice, whichever comes first. A carrier that needs more time must ask the FMCSA Division Administrator for its home state within 5 days after the driver’s notice. If an inspection happens during a malfunction, the driver shows the paper records instead.
FMCSA also keeps a public list of revoked ELDs, which are devices it found don’t meet the technical specifications. Carriers should check it when choosing or renewing a device.
Roadside Inspections and Record Retention
At an inspection, the driver must produce and transfer the hours-of-service records from the ELD when an authorized safety official asks, following the carrier’s instruction sheet (49 CFR 395.24(d)). Our guides to the levels of DOT inspections and DOT inspection tips explain what else is checked.
- Carrier: keeps records of duty status and supporting documents for each driver for at least 6 months (49 CFR 395.8(k)), plus a back-up copy of ELD records for 6 months on a device separate from the original (49 CFR 395.22(i)).
- Driver: keeps the records for the previous 7 consecutive days available for inspection while on duty.
- Supporting documents: include bills of lading or equivalent trip documents, dispatch or trip records, expense receipts for on-duty time, and fleet management system messages (49 CFR 395.11). Drivers must submit them to the carrier within 13 days.
An ELD records hours and location, but the route still has to fit the truck. Our semi truck GPS guide covers truck-specific navigation.
