If you made a mistake just edit your duty status. Per ELD mandate you are not allowed to edit “Driving” status, you can only annotate it.
Follow the instructions steps:
From Dashboard view (or main menu), tap Logs.
Select a daily log you want to edit.
Select a duty status you want to change. Tap Edit.
Edit the Duty Status, Start and End time.
Enter a Note for the change you made and tap Save.
