In plain English
This marks the real moment movement begins from the place of departure. It records the actual date and time when the shipment, or the vehicle carrying it, physically leaves. It distinguishes what truly happened from what may have been planned.
In context
Here, ATD reports the date and time when the shipment, or the vehicle carrying it, actually left its departure location.
- Situation
- Coordinating freight quotes, booking, consolidation, handoff, and transport documents
- What it communicates

Meaning limits
By itself, ATD does not show whether the departure was early, late, or on time.
Examples
“The truck was due to leave at 06:00, but its ATD was 06:18.”
“After the lorry left the depot, the dispatcher recorded the ATD.”
