What you cannot do as an additional driver
Some actions are only available to the main driver — the person who made the booking. As an additional driver:
You cannot send messages — You can view the conversation, but you cannot participate. Only the main driver can message the host through the trip.
You cannot view the cost — The financial details of the booking (total cost, receipts, charge breakdown) are only visible to the main driver.
You cannot change the dates — Pickup and return dates can only be modified by the main driver.
You cannot change the location — The pickup and return location can only be changed by the main driver.
You cannot add or remove drivers — Only the main driver can manage the list of additional drivers.
You cannot cancel the trip — Cancellation is only possible by the main driver.

Protection plan coverage
As an additional driver, you are automatically covered by the same protection plan that the main driver selected for the booking. No separate coverage is needed and there is no extra charge for adding you.
Good to know
If you need something you cannot do yourself (such as changing dates or cancelling), ask the main driver to make the change from their own account.
If the main driver switches to a different vehicle through a change request, additional drivers are not automatically transferred to the new booking — the main driver will need to add you again.
If you experience any issue during the trip, you can always contact Sync support directly.
