EXHIBIT 9.1

                           VOTING TRUST AGREEMENT


        This Voting Trust Agreement is made and entered into by Lawrence D.
Crouse, Trustee under the three Gerdin Educational Trusts created by trust
instrument dated August 11, 1986, for the benefit of, respectively, Michael
Gerdin, Julie Gerdin and Angela Gerdin (collectively the "Educational
Trusts"), as Trustor, and Lawrence D. Crouse, as Trustee. 

                           PRELIMINARY STATEMENT

        The Educational Trusts collectively own 645,119 shares of the 
issued and outstanding common stock of Heartland Express, Inc., a Nevada 
corporation ("Heartland").  Trustor believes that it is in the best 
interests of the beneficiaries of the Educational Trusts to place 
Educational Trusts' shares in a voting trust.  For that reason, Trustor has 
established this Voting Trust and shall transfer the Educational Trusts' 
shares to this Voting Trust, to be voted under the terms and conditions set 
forth in this Voting Trust Agreement. 

        NOW, THEREFORE, it is agreed as follows:

        1.     Definitions.

shall refer to Lawrence D. Crouse, Trustee of the Educational Trusts. 

        C.     The term "Trustee" as used in this Voting Trust Agreement 
shall refer initially to Lawrence D. Crouse in his capacity as Trustee of 
this Voting Trust, and to any other person or entity acting as Trustee, 
Trustees or Successor Trustee.  The term "Trustee" may be construed in the 
singular or plural, and as masculine, feminine or neuter, as the context or 
circumstances may require.

      D.    The term "Trust Stock" shall refer to the 645,119 shares of
Heartland voting common stock owned by the Educational Trusts, and to any 
new, substitute or additional shares or securities with voting rights, or 
which may be converted to shares with voting rights, resulting from any 
dividend, reclassification, readjustment or other change in the capital 
structure of Heartland.

      E.     "Voting Shares" of Heartland Express shall refer to voting 
shares of Heartland voting common stock, and any securities of Heartland 
that have voting rights or are convertible into or give the right to 
acquire voting shares of Heartland.

this ____ day of ____________, 1997.

                                     ______________________________
                                      Lawrence D. Crouse, Trustee


       5.      Transfer of Certificates.  The voting trust certificates
shall be transferable at the Trustee's principal office at 2906 South 102nd 
Street, Omaha, Nebraska  68124 (and at such other office as the Trustee may 
designate by an instrument signed by him and sent by mail to the registered 
holders of voting trust certificates), on the books of the Trustee, by the 
registered owner thereof, either in person or by attorney thereto duly 
authorized, upon surrender of their voting trust certificate and execution 
of an irrevocable Assignment in a form acceptable to Trustee.  The Trustee 
may treat the registered holder as owner thereof for all purposes, but he 
shall not be required to deliver stock certificates hereunder without the 
surrender of such voting trust certificates.

     6.    Sale of Shares.  The registered holder of any Voting Trust
Certificate may, at any time, make a bona fide sale of shares represented 
by the Certificate to a non-affiliated third party.  Upon written notice of 
any such sale, the Trustee shall promptly deliver shares of this Trust in
accordance with the written direction of the registered holder.  The
registered holder shall be entitled to the entire proceeds from the sale of
any shares represented by the holder's Voting Trust Certificates.

     7.     Termination Procedure.  

    (a)     Upon the termination of this Agreement at any time, as 
hereinafter provided, the Trustee, at such time as he may choose during the 
period commencing twenty (20) days before and ending twenty (20) days after 
such termination, shall mail written notice of such termination to the 
registered owners of the voting trust certificates, at the addresses 
appearing on the Trustee's transfer books.  After the date specified in any 
such notice (which date shall be fixed by the Trustee), the voting trust 
certificates shall cease to have any effect, and their holders shall have 
no further rights under this Agreement other than to receive certificates 
for shares of Heartland's stock or other property distributable under the 
terms hereof and upon the surrender of such voting trust certificates.

       (b)     Within thirty (30)days after the termination of this 
Agreement, the Trustee shall accomplish the transfer, to the registered 
holders of all voting trust certificates, of the number of shares of 
Heartland's capital stock, represented by voting trust certificates, upon 
the surrender thereof properly endorsed, such delivery to be made in each 
case at the Trustee's office.

      (c)     This Voting Trust Agreement may be terminated at any time by 
the Trustor, upon his determination that the termination of this Voting 
Trust Agreement will not result in inclusion of the Heartland shares in the 

<PAGE>

estates of Russell A. Gerdin or Ann S. Gerdin for federal estate tax 
purposes, under Section 2036(b) of the Internal Revenue Code of 1986 as 
amended or corresponding provisions of any future internal revenue law.

       8.     Dividends.  

      (a)    The holder of each voting trust certificate shall be entitled 
to receive payments equal to the cash dividends, if any, received by the 
Trustee upon a like number and class of shares of Heartland's capital stock 
as is called for by each such voting trust certificate.  If any dividend in 
respect of the stock deposited with the Trustee is paid, in whole or in 
part, in Heartland's voting shares, the Trustee shall likewise hold, 
subject to the terms of this Agreement, the certificates for securities 
which are received by him on account of such dividend.  The holder of each 
voting trust certificate representing stock on which such dividend has been 
paid shall be entitled to receive a voting trust certificate issued under 
this Agreement for the number of shares and class of stock received as such 
dividend with respect to the shares represented by such voting trust 
certificate.  Holders entitled to receive the dividends described above 
shall be those registered as such on the Trustee's transfer books at the 
close of business on the day fixed by Heartland for the taking of a record 
to determine those holders of its stock entitled to receive such dividends.

      (b)     If any dividend in respect of the stock deposited with the
Trustee is paid other than in cash or in voting shares of Heartland, then 
the Trustee shall distribute the same among the holders of voting trust
certificates registered as such at the close of business on the day fixed 
by Heartland for taking a record to determine the holders of shares 
entitled to receive such distribution.  Such distribution shall be made to 
such holders of voting trust certificates ratably, in accordance with the 
number of shares represented by their respective voting trust certificates.

       (c)      In lieu of receiving cash dividends upon the capital stock 
of Heartland and paying the same to holders of voting trust certificates 
pursuant to the provisions of this Agreement, the Trustee may instruct 
Heartland in writing to pay such dividends to the holders of the voting 
trust certificates.  Upon receipt of such written instructions and 
acceptance by Heartland, and  until revoked by the Trustee, all liability 
of the Trustee with respect to such dividends shall cease.  The Trustee may 
at any time revoke such instructions and by written notice to Heartland 
direct it to make dividend payments to the Trustee.

      9.     Subscription Rights.  If any stock or other securities of
Heartland are offered for subscription to the holder of its capital stock
deposited hereunder, the Trustee, promptly upon receipt of notice of such
offer, shall mail a copy thereof to each holder of the voting trust
certificates.  Upon receipt by the Trustee, at least five (5) days prior to
the last day fixed by Heartland for subscription and payment, of a request
from any such registered holder of voting trust certificates to subscribe 
in his behalf, accompanied with the sum of money required to pay for such 
stock or securities (not in excess of the amount subject to subscription in 
respect of the shares represented by the voting trust certificate held by 
such certificate holder), the Trustee shall make such subscription and 
payment.  Upon receiving from Heartland the certificates for shares or 

<PAGE>

securities so subscribed for, the Trustee shall issue to such holder a 
voting trust certificate in respect thereof if the shares or securities 
received are voting shares.  If, however, the shares or securities are not 
voting shares, the Trustee shall mail or deliver such securities to the 
certificate holder in whose behalf the subscription was made, or may 
instruct Heartland to make delivery directly to the certificate holder 
entitled thereto.

       10.      Dissolution of Heartland.  In the event of the dissolution 
or total or partial liquidation of Heartland, whether voluntary or 
involuntary, the Trustee shall receive the moneys, securities, rights, or 
property to which the holders of Heartland's capital stock deposited 
hereunder are entitled, and shall distribute the same among the registered 
holders of voting trust certificates in proportion to their interests, as 
shown by the books of the Trustee.  Alternatively, the Trustee may in his 
discretion deposit such moneys, securities, rights, or property with any 
federally insured bank or trust company doing business in Iowa City, Iowa, 
with authority and instructions to distribute the same as above provided, 
and upon such deposit, all further obligations or liabilities of the 
Trustee in respect of such moneys, securities, rights, or property so 
deposited shall cease.

       11.        Reorganization of Heartland.  In the event of any merger,
consolidation, exchange, sale of assets, or other business combination in
which the Heartland stockholders receive securities of another entity, then
in connection with such transfer the term "Heartland" for all purposes of 
this Agreement shall be deemed to include such successor entity, and the 
Trustee shall receive and hold under this Agreement any of such successor's 
securities having voting power of that are convertible into or give the 
holder the right to acquire voting securities, received on account of the 
ownership of the securities held hereunder prior to such business 
combination.  Voting trust certificates issued and outstanding under this 
Agreement at the time of such business combination may remain outstanding 
or the Trustee may, in his discretion, substitute for such voting trust 
certificates new voting trust certificates in appropriate form, and the 
terms "stock", "capital stock" and "securities" as used herein shall be 
taken to include any securities having voting power of that are convertible 
into or give the holder the right to acquire voting securities, which may 
be received by the Trustee in lieu of all or any part of Heartland's 
capital stock.

       12.        Rights of Trustee.

     (a)       Until the actual delivery to the holders of voting trust
certificates issued hereunder of stock certificates in exchange therefor, 
and until the surrender of the voting trust certificates for cancellation, 
the Trustee shall have the right, subject to the provisions of this 
paragraph hereinafter set forth, to exercise, in person or by his nominees 
or proxies, all stockholders' voting rights and powers in respect of all 
stock deposited hereunder, and to take part in or consent to any corporate 
or stockholders' actions of any kind whatsoever. The right to vote shall 
include the right to vote for the election of directors, and in favor of or 
against any resolution or proposed action of any character whatsoever, 
which may be presented at any meeting or require the consent of Heartland's 
stockholders.  Without limiting such general right, it is understood that 
such action or proceeding may include, upon terms satisfactory to the 

<PAGE>

Trustee or his nominees or proxies thereto appointed by him, mortgaging, 
creating a security interest in, and pledging of all or any part of 
Heartland's property, the lease or sale of all or any part of its property, 
for cash, securities, or other property, and the dissolution of Heartland, 
or its consolidation, merger, reorganization, or recapitalization.

       (b)      In voting the stock held by him hereunder either in person 
or by his nominees or proxies, the Trustee shall exercise his best judgment 
to select suitable directors of Heartland, and shall otherwise, insofar as 
he may as a stockholder of Heartland, take such part or action in respect 
to the management of its affairs as he may deem necessary so as to be kept 
advised on the affairs of Heartland and its management.  In voting upon any 
matter that may come before him at any stockholders' meeting, the Trustee 
shall exercise like judgment.  The Trustee, however, shall not be 
personally liable for any action taken pursuant to his vote or any act 
committed or omitted to be done under this Agreement, provided that such 
commission or omission does not amount to willful misconduct on his part 
and that he at all times exercises good faith in such matters.

       13.     Trustees.  

      (a)       The Trustee (and any successor Trustee) may at any time 
resign by mailing to the registered holders of voting trust certificates a 
written resignation, to take effect ten (10) days thereafter or upon its 
prior acceptance.  In the event Lawrence D. Crouse should die, resign, or 
for any reason become unable to serve, then that person or entity 
designated by him in writing shall serve as Trustee hereunder.  If Lawrence 
D. Crouse shall fail to make such a designation or if his designation fails 
or qualify, dies, resigns or otherwise becomes unable to serve, then 
Richard Reiser of Omaha, Nebraska, shall serve as successor Trustee, and if 
Richard Reiser is for any reason unable or unwilling to serve, then Hill 
State Bank and Trust shall serve as the Trustee.  

      (b)      The rights, powers, and privileges of the Trustee named 
hereunder shall be possessed by the successor Trustees, with the same 
effect as though such successors had originally been parties to this 
Agreement.  The word "Trustee," as used in this Agreement, means the 
Trustee or any successor Trustees acting hereunder, and shall include both 
the single and the plural number.  The words "he," "him," and "his," as 
used in this Agreement in reference to the Trustee shall mean "they," 
them," and "their," respectively, when more than one Trustee is acting 
hereunder.

       14.      Term.

       (a)      This Agreement shall continue in effect until the fifteenth 
anniversary of its execution (subject to extension as hereinafter set 
forth).  The voting trust is irrevocable and shall not be subject to 
amendment or modification.  

        (b)      At any time within two (2) years prior to the time
of expiration of the term hereof as theretofore extended, the holders of 
all of the voting trust certificates hereunder may, by agreement in writing 

<PAGE>

and with the Trustee's written consent, extend the duration of this 
Agreement for an additional period not exceeding fifteen (15) years.  In 
the event of such extension, the Trustee shall, prior to the time of 
expiration as herein above provided, as originally fixed, or as theretofore 
extended, as the case may be, file in Heartland's principal office, a copy 
of such extension agreement, and of the consent thereto.  Thereupon the 
duration of this Voting Trust Agreement shall be extended for the period 
fixed by such extension agreement, provided, however, that no such 
extension agreement shall extend the term of this Agreement beyond the 
maximum period then permitted by applicable law or affect the rights or 
obligations of persons not parties thereto.

        15.      Compensation and Reimbursement of Trustee.  The 
Trustee shall serve without compensation.  The Trustee shall have the right
to incur and pay such reasonable expenses and charges, to employ and pay 
such agents, attorneys, and counsel as he may deem necessary and proper to
effectuate this Agreement.  All such expenses or charges incurred by and 
due to the Trustee may be deducted from the dividends or other moneys or 
property received by him on the stock deposited hereunder.  Nothing herein 
contained shall disqualify the Trustee or successor Trustees, or 
incapacitate him or them from serving Heartland or any of its subsidiaries 
as officer or director, or in any other capacity, and in any such capacity 
receiving compensation.

       16.       Notice.

       (a)       Unless otherwise specifically provided herein, any notice 
to or communication with the holders of the voting trust certificates
hereunder shall be deemed to be sufficiently given or made if enclosed in
postpaid envelopes (regular not registered mail) addressed to such holders
at their respective addresses appearing on the Trustee's transfer books, 
and deposited in any post office or post office box.  The addresses of the 
holders of voting trust certificates, as shown on the Trustee's transfer 
books, shall in all cases be deemed to be the addresses of voting trust 
certificate holders for all purposes under this Agreement, without regard 
to what other or different addresses the Trustee may have for any voting 
trust certificate holder on any other books or records of the Trustee.  
Every notice so given shall be effective, whether or not received, and the 
date of mailing shall be the date such notice is deemed given for all 
purposes.

        (b)     Any notice to the Trustee hereunder may be enclosed in a
postpaid envelope and sent by registered mail to the Trustee, addressed to 
him at such addresses as he may from time to time furnish in writing to 
Heartland, and if no such address had been so furnished by the Trustee, 
then to him in care of Heartland.

        (c)     All distributions of cash, securities, or other 
property hereunder by the Trustee to the holders of voting trust 
certificates may be made, in the Trustee's discretion, by mail (regular or 
registered mail, as the Trustee may deem advisable), in the same manner as 
hereinabove provided for the giving of notices to the holders of voting 
trust certificates.

<PAGE>

         17.     Entire Agreement.  This Agreement supersedes all prior 
agreements between the parties relating to its subject matter.  There are 
no other understandings or agreements between them concerning the subject 
matter.

         18.      Nonwaiver.  No delay or failure by a party to exercise 
any right under this Agreement, and no partial or single exercise of that 
right, shall constitute a waiver of that or any other right, unless 
otherwise expressly provided herein.

         19.      Headings.  Headings in this Agreement are for convenience
only and shall not be used to interpret or construe its provisions.

         20.      Governing Law.  This Agreement shall be construed 
in accordance with the laws of the State of Nevada.

         21.      Counterparts.  This Agreement may be executed in two 
or more counterparts, each of which shall be deemed an original but all of 
which together shall constitute one and the same instrument.

         22.       Binding Effect.  The provisions of this Agreement shall 
be binding upon and inure to the benefit of each of the parties and their
respective legal representatives, successors and assigns.

         IN WITNESS WHEREOF, the Grantor and the Trustee have executed this
Voting Trust Agreement on the 6th day of June, 1997.
