Changing Duty Status
For the most accurate records, you must change your duty status in the Garmin eLog™ app every time you change your driving status, such as when you start driving, take a break, switch drivers, or change the type of driving you are doing. The Garmin eLog adapter automatically switches to driving status when the vehicle's diagnostic port reports a speed greater than or equal to five miles per hour. The vehicle is stopped when the diagnostic port reports a speed of zero miles per hour.
NOTE:
The vehicle must be stopped to change duty status. You cannot manually change duty status while you are driving.
