Welcome to the Geotab forums!
Geotab Drive can be used for DVIR only and some customers do use it that way. We recommend changing the clearance options for users by changing the following:
Remove "Administer HOS Logs", "View HOS Logs", "Send Messages, and "View Messages".
This will prevent HOS logs being made for the DVIR only user, and will remove the HOS and Messages buttons from the app to make sure it is simple for the user to do their DVIR and move on.
If the DVIRs are done at a location using Wi-Fi you will not need a device with cell-enabled. Other recommendations for DVIR use involve another clearance called "Mark DVIR logs as repaired". If the company wants to only allow specific users the ability to confirm a DVIR is marked as repaired or not, having this clearance option on those users and not others can help keep track of things.
Let us know if there is anything else we can help you with.
