If you would like your drivers to still be able to change their off-duty and on-duty statuses when they are away from their vehicle or Driver App, they can do so by using Kiosk Mode through the Samsara Driver Portal. This will ensure more accurate logs and less time spent editing on-duty time at the beginning and end of their shift.
They will start by accessing the Driver Portal. Find out how to do a driver can do this here: Driver Portal
You will see how to change duty-status below.
To enable this feature for your drivers, go to Settings > HOS/DVIR and toggle on both Persistent Duty Status and Kiosk mode
