           Russell A. Gerdin previously filed Schedule 13G pursuant to
                        the provisions of Rule 13d-1(d).

Item 1. Security and Issuer.

     This  statement  on Schedule 13D (this  "Statement")  relates to the Common
Stock,  par value $0.01 per share (the "Common  Stock"),  of Heartland  Express,
Inc., a Nevada  corporation (the "Issuer").  The principal  executive offices of
the Issuer are located at 901 North Kansas Avenue, North Liberty, IA 52317.

Item 2. Identity and Background.

     (a) This  Statement  is being filed  jointly on behalf of Russell A. Gerdin
and Ann S. Gerdin (together, the "Reporting Persons"). The Reporting Persons may
be deemed to be members of a group within the meaning of Section 13(d)(3) of the
Securities  Exchange  Act of 1934,  as  amended.  The filing of this  Statement,
however, should not be deemed an admission that the Reporting Persons comprise a
group for purposes of Section 13(d)(3).

     (b) The  business  address of the  Reporting  Persons  is 901 North  Kansas
Avenue, North Liberty, IA 52317.

     (c)

Mr. Gerdin

     The principal  occupation of Mr. Gerdin is chief  executive  officer of the
Issuer. The principal business address of the Issuer is 901 North Kansas Avenue,
North Liberty, IA 52317.

Mrs. Gerdin

     The principal occupation of Mrs. Gerdin is homemaker.  She is also involved
in civic and  philanthropic  commitments.  Mrs. Gerdin's business address is 901
North Kansas Avenue, North Liberty, IA 52317.

     (d) - (e) During the last five years,  neither of the Reporting Persons has
been: (i) convicted in a criminal  proceeding  (excluding  traffic violations or
similar  misdemeanors);  or (ii) a party to a civil  proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
was or is  subject  to a  judgment,  decree  or  final  order  enjoining  future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws.

     (f) The Reporting Persons are citizens of the United States of America.

Item 3. Source and Amount of Funds or Other Consideration.

     On July 11, 2007,  Mr. Gerdin  became  trustee over shares owned by certain
grantor  attained  annuity trusts  established by Mrs. Gerdin for the benefit of
Mr. and Mrs. Gerdin's children ("Mrs.  Gerdin's GRATS"),  and Mrs. Gerdin became
trustee over shares owned by certain grantor attained annuity trusts established
by Mr. Gerdin for the benefit of Mr. and Mrs. Gerdin's  children ("Mr.  Gerdin's
GRATS" and together with Mrs.  Gerdin's  GRATS,  the "GRATS").  By virtue of Mr.
Gerdin becoming trustee of Mrs.  Gerdin's GRATS, he received  dispositive  power
over the shares owned by Mrs.  Gerdin's GRATS. By virtue of Mrs. Gerdin becoming
trustee of Mr. Gerdin's GRATS,  she received  dispositive  power over the shares
owned by Mr.  Gerdin's GRATS.  Thus, Mr. and Mrs.  Gerdin are each  individually
deemed to  beneficially  own the shares  owned by the GRATS over which he or she
serves as trustee pursuant to Rule 13d-3 of the Securities Exchange Act of 1934,
as amended. Except for 8,000,000 shares owned by Mrs. Gerdin's GRATS, over which
Mr. Gerdin had voting power,  neither of the Reporting  Persons has voting power
over the shares owned by the GRATS.  The Reporting  Persons did not pay money or
other  consideration  in connection  with becoming the trustee of the respective
GRATS or in obtaining beneficial ownership of the shares owned by the GRATS.



     By virtue of becoming the trustees,  the  Reporting  Persons were deemed to
have acquired beneficial ownership over the following number of shares:

     Mr. Gerdin: 12,372,510 shares
     Mrs. Gerdin: 3,710,555 shares

     By virtue of becoming the respective  trustees,  the Reporting Persons have
an obligation to file this Schedule 13D.

     See Item 4 also.

Item 4. Purpose of Transaction.

     In addition to the  transaction  described  in Item 3, in the future,  each
Reporting Person from time to time may use his or her personal funds to purchase
Common  Stock  for  investment  purposes.  Depending  on the  volume of any such
purchases, if any are made, it is possible that either Mr. Gerdin or Mrs. Gerdin
or both Mr. and Mrs. Gerdin  together,  may become the beneficial  owner of more
than 50% of the outstanding  Common Stock of the Issuer.  The Reporting  Persons
have not made any such  purchases to date. If any such  purchases are made,  the
Reporting  Persons may cease buying the Common Stock at any time.  The Reporting
Persons may purchase Common Stock in the open market or in privately  negotiated
transactions,  or otherwise.  The Reporting Persons intend to participate in and
influence the affairs of the Issuer  through the exercise of their voting rights
with respect to their shares of Common  Stock.  In addition,  Mr.  Gerdin is the
Chief  Executive  Officer and a Director of the Issuer and, as a result,  in the
ordinary  course or  otherwise  may take actions to  influence  the  management,
business, and affairs of the Issuer.

     Other  than as  described  or  contemplated  in Item 3,  this Item 4, or as
announced  publicly,  neither of the  Reporting  Persons have any other  present
plans or  proposals  with  respect to any action  referred  to in  sections  (a)
through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

     (a) As of July 31,  2008  there  were  96,157,633  shares of  Common  Stock
outstanding.  As of  the  date  hereof,  Mr.  Gerdin  may  be  deemed  to be the
beneficial  owner (pursuant to Rule 13d-3) of an aggregate of 28,169,262  shares
of Common Stock, representing  approximately 29.3% of the issued and outstanding
shares of Common  Stock of the Issuer.  The shares of Common  Stock deemed to be
beneficially  owned by Mr. Gerdin  consist of 17,385,980  shares of Common Stock
owned by the Russell A. Gerdin Revocable Trust ("Mr. Gerdin's Revocable Trust");
(ii) 1,936,276 shares of Common Stock  represented by voting trust  certificates
owned by Gerdin Family  Investments,  LP ("GFI");  and (iii) 8,847,006 shares of
Common Stock owned by Mrs. Gerdin's GRATS.

     As of the date hereof, Mrs. Gerdin may be deemed to be the beneficial owner
(pursuant to Rule 13d-3) of an aggregate of  10,285,612  shares of Common Stock,
representing  approximately 10.7% of the issued and outstanding shares of Common
Stock of the Issuer.  The shares of Common Stock deemed to be beneficially owned
by Mrs. Gerdin consist of (i) 9,032,726  shares of Common Stock owned by the Ann
S. Gerdin  Revocable  Trust;  and (ii)  1,252,886  shares owned by Mr.  Gerdin's
GRATS.

     As a result of the foregoing,  as of the date hereof, the Reporting Persons
together may be deemed to be the beneficial  owners  (pursuant to Rule 13d-3) of
an aggregate 38,454,874 shares of Common Stock, representing approximately 40.0%
of the issued and outstanding shares of Common Stock of the Issuer.



     (b) Mr.  Gerdin  has the sole  power to vote  23,641,106  of the  shares of
Common Stock of the Issuer for which  beneficial  ownership is reported.(1)  Mr.

     (c) Not applicable.

     (d) Not applicable.

     (e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to
     Securities of the Issuer.

     Except as  described in Items 3, 4, and 5 of this  Statement,  there are no
contracts,  arrangements,  understandings, or relationships (legal or otherwise)
among the Reporting  Persons and any person,  with respect to any  securities of
the Issuer,  including,  but not  limited  to,  transfer or voting of any of the
securities  of the  Issuer,  finder's  fees,  joint  ventures,  loan  or  option
