This closes out the current driver's segment today and starts a new one. Salary for this trip will be split evenly between all drivers as a starting point — edit each driver's share after.

No new documents, expenses, or driver changes can be made after finalization. Any active driver segment will post its salary now.

This cannot be undone — the OSO number will remain but no further action can be taken on it.

This reopens the OSO for edits — driver, expenses, and documents can be changed again.

Remove this driver from the trip? This cannot be undone.
