Handling Unassigned ELD Driving Time After a Truck or Shift Change

An ELD may display unassigned driving recorded before you took over a truck. When nobody is logged in, the device records operation under the Unidentified Driver profile. While safely parked, compare timestamps, the log’s time zone, vehicle details and locations with handoff and dispatch records.

Under 49 CFR § 395.32, review unassigned driving when prompted. Claim your own driving and explicitly reject records that are not yours. You may claim only your portion of a longer interval. Limited remaining hours do not justify rejecting driving you performed.

Give the carrier specific records to investigate. The carrier must assign driving to the correct driver or annotate why it remains unassigned, retaining unidentified-driving records for at least six months from receipt.

If you accept another driver’s time by mistake, follow the supported correction procedure. Mistakenly claimed driving may return to the unidentified profile for the correct driver to claim; automatically recorded driving totals cannot be reduced. Annotate changes and recertify corrected, previously submitted logs. Carrier-proposed edits require driver confirmation or rejection, appropriate corrections, recertification and resubmission. Team-driver reassignment requires reciprocal co-driver entries for that period and confirmation by both drivers.

Authorized personal conveyance and yard moves must be selected before the activity and deselected afterward. If selection was missed, truthfully annotate the unidentified record. Do not claim it and retroactively convert it to PC or YM. An annotation does not guarantee exemption from enforcement.

Original records remain available after correction, and rejected events remain reviewable at roadside. Changing trucks does not reset HOS. With incompatible ELDs, enter missing duty-status information or provide other-system printouts covering the current 24 hours and previous seven consecutive days.

An unidentified-driving diagnostic alone does not establish an ELD malfunction. Follow carrier and provider recommendations, then review your personal log, certification and remaining hours. These general federal requirements were checked on October 5, 2026; device-specific instructions and actual records govern the necessary operational steps.
