A truck's current driver is useful to know. The previous assignment can matter too when the office is tracing a document, service note, or question from an earlier shift. Replacing a name in a single spreadsheet cell removes that context.
Give the truck a stable identity
Use the same unit number and vehicle record over time. A change of driver, yard, or status should not create a new truck simply because the day-to-day assignment changed. Confirm the truck identity before recording the new assignment so similar units are not mixed up.
Record the transition clearly
When an assignment changes, capture the person and effective dates your office can verify. If the reason matters to your internal process, keep a concise note without adding unrelated personal information. Review the current assignment and the history after saving. A supervisor should be able to understand which period each assignment describes.
Do not confuse assignment with a live job
An employee-to-truck assignment describes a relationship in company records. It does not show where the truck is now, who accepted a particular call, or whether a driver was qualified for every job during that period. Those questions need the appropriate dispatch, source, and compliance records.
TowAdmin includes employee and truck records with assignment history. Keep source documents with the right person or vehicle and review the fleet document workspace for the truck side. The driver credential workspace explains how the office can keep each person's dates and evidence separate from the vehicle.
