What is the difference between an “edit” and an “annotation”?

An edit is a change to an electronic logging device (ELD) record that does not overwrite the original record, while an annotation is a note related to a record, update, or edit that a driver or authorized support personnel may input to the ELD. Section 49 CFR 395.30(c)(2) requires that all edits, whether made by a driver or the motor carrier, be annotated to document the reason for the change. For example, an edit showing time being switched from �off duty� to �on-duty not driving� could be annotated by the carrier to note, �Driver logged training time incorrectly as off duty.� This edit and annotation would then be sent to the driver for approval.
