You can use normal join like this:

Vehicle::join('staff','vehicles.staff_id','staff.id')
         ->select(
                  'vehicles.id',
                  'vehicles.name',
                  'staff.id as staff_id',
                  'staff.name'
          )
         ->get();

Since, you can't take both id at once in a join because only one is allowed. So, you can staff's id as staff_id.

You can add vehicle id condition with where clause like:

Vehicle::join('staff','vehicles.staff_id','staff.id')
         ->where('vehicle.id',1)
         ->select(
                  'vehicles.id',
                  'vehicles.name',
                  'staff.id as staff_id',
                  'staff.name'
          )
         ->get();

Hope you understand.
