Null edits
Recalculate driver timers without changing logs
What is a null edit?
A null edit is an admin edit that changes a duty status to the same status it already has. This forces the system to recalculate hours‑of‑service timers without changing the driver’s log history or status.
Null edits are used only to correct timer calculations; they do not intentionally change what the driver actually did.
When to use a null edit
Use a null edit when timers are out of sync but the duty status history is correct, for example:
-
Timers show incorrectly after a duty status change
-
Timers show incorrectly after a split sleeper berth break
If the underlying duty status is wrong, perform a normal admin edit instead of a null edit.
Comment requirements
Always add a clear comment explaining why the null edit was performed.
Example:
Null edit to recalculate timers – timers were showing incorrectly after split sleeper berth.
Comments create an audit trail and help explain the change during log reviews or inspections.
How to perform a null edit
-
Open the driver’s log for the affected date.
-
Locate the duty status where timers became incorrect.
-
Start an admin edit on that duty status.
-
Set the duty status to the same status (for example, Off Duty → Off Duty).
-
Add a detailed comment describing the reason for the null edit.
-
Save the edit and complete any required approval steps.
After saving, the system recalculates timers based on the existing duty status history, correcting the out‑of‑sync timers without altering the driver’s actual log.
