     Re: Securities and Exchange Commission ("SEC") Comment Letter dated May 22,
     2008 regarding Heartland Express,  Inc. Form 10-K for the fiscal year ended
     December 31, 2007, File No. 000-15087

Dear Ms. Cvrkel:

The  following is in response to the comments  and requests for  information  in
your  letter  dated May 22,  2008  related to our 2007 Form 10-K.  We have today
electronically  filed with the SEC this response to your letter. A courtesy copy
of the filing has been forwarded to Ms. Yu via facsimile transmission at the fax
number listed above.

     1.   We note from your consolidated  statements of cash flows that you have
          presented purchases and sales of municipal bonds and other investments
          on a net  basis in your  consolidated  statements  of cash  flows.  In
          future  filings,   please  revise  to  present   purchases  sales  and
          maturities  of  investments  on a gross  basis  in  your  consolidated
          statement of cash flows as required by paragraph 18 of SFAS No. 115.

          Response:  We note the Staff's comment  regarding gross basis of sales
          and maturities of investments  in the  consolidated  statement of cash
          flows pursuant to paragraph 18 of SFAS No. 115. We respectfully submit
          that the Company has  presented  purchases,  sales and  maturities  of
          investments  on a net basis per guidance,  under  paragraph 13 of SFAS
          No. 95, which states,  "Items that qualify for net  reporting  because
          their turnover is quick, their amounts are large, and their maturities
          are short are cash receipts and payments pertaining to (a) investments
          (other than cash  equivalents),  (b) loans  receivable,  and (c) debt,
          providing  that the  original  maturity of the asset or  liability  is
          three   months  or  less."  The  Company  has   determined   that  net
          presentation   is  more  meaningful  to  investors  as  the  Company's
          investments  consist of auction rate  securities  which  typically are
          bought and sold every 35 days. The Company's historical  participation
          in  auctions  every 35 days  equates  to an  annual  turn-over  of the
          Company's  investment portfolio  approximately 10 times annually.  The
          Company  believes that net  increases and decreases to the  investment
          portfolio  and  not  the  gross   increases  and  decreases  are  more
          beneficial  to  investors  based  on the  underlying  activity  of the
          Company's investments.



     2.   We note  from  the  disclosures  provided  in  Notes 2 and 4 that  the
          Company  adopted  SAB  108 by  recording  a $15.9  million  cumulative
          adjustment  to retained  earnings  during the year ended  December 31,
          2006 to record a  previously  unrecorded  state  income  tax  exposure
          liability  of $11.8  million and related  increase in the deferred tax
          liability of $4.1 million. We also note from the disclosures  provided
          that the amount  recorded  pertains to potential state tax liabilities
          for the years 1996 through  2005 and the impact on deferred  taxes for
          those same years. We also note from your disclosures that these errors
          were  considered  immaterial  under the Company's  previous  method of
          evaluating misstatements.

          Please  tell us and  expand  future  filings  to  disclose  the method
          previously utilized to evaluate misstatements prior to the adoption of
          SAB 108.  Also,  please  provide us with an  analysis  indicating  the
          dollar amounts of the  misstatements  that existed with respect to the
          various   periods  that  were   misstated   along  with   managements'
          materiality analysis of the misstatements prior to the adoption of SAB
          108. We may have further comment upon receipt of your response.

          Response:  Prior to the adoption of Staff Accounting Bulletin No. 108,
          "Considering the Effects of Prior Year  Misstatements when Quantifying
          Misstatements in Current Year Financial  Statements,"  ("SAB 108") the
          Company used the income statement,  "rollover"  approach to evaluating
          misstatements.  In using the rollover approach, the Company quantified
          the misstatement  based on the amount of the error  originating in the
          current year  consolidated  statement of operations  and thus ignoring
          the effect of correcting the portion of the current year  consolidated
          balance sheet misstatement that originated in prior years. The Company
          will  incorporate  the  following  disclosure  in the footnotes to the
          consolidated  financial statements in future filings in which the 2006
          financial statements are presented:

               "In September 2006, the SEC issued Staff Accounting  Bulletin No.
               108,  Considering  the Effects of Prior Year  Misstatements  when
               Quantifying  Misstatements  in Current Year Financial  Statements
               (SAB 108),  to  address  diversity  in  practice  in  quantifying
               financial statement misstatements.  SAB 108 requires an entity to
               quantify misstatements using a balance sheet and income statement
               approach  and to  evaluate  whether  either  approach  results in
               quantifying  an error  that is  material  in  light  of  relevant
               quantitative  and qualitative  factors.  Prior to the adoption of
               SAB 108 the  Company  quantified  misstatements  using the income
               statement  approach  whereby errors were quantified  based on the
               amount of the error  originating in the current year consolidated
               statement  of  operations   and  thus  ignoring  the  effects  of
               correcting the portion of the current year  consolidated  balance
               sheet  misstatement  that originated in prior years.  SAB 108 was



               effective as of the beginning of the Company's  2006 fiscal year,
               allowing a one-time transitional  cumulative effect adjustment to
               retained  earnings as of January 1, 2006 for errors that were not
               previously  deemed material,  but are material under the guidance
               in SAB 108. The Company adopted the provisions of SAB No. 108 and
               recorded a $15.9 million cumulative  adjustment to the January 1,
               2006 retained  earnings for a previously  unrecorded state income
               tax exposure  liability and related  deferred tax liability.  The
               amount   recorded   pertains  to   potential   state  income  tax
               liabilities  for the years  1996  through  2005 and the impact on
               deferred tax liabilities for those same years.  These errors were
               considered   immaterial  under  the  Company's   previous  income
               statement method of evaluating misstatements."

          Management's materiality assessment

          The  Company   has  used  the   guidance  as  set  forth  in  SAB  99,
          "Materiality" in assessing the materiality by period.  Quantitatively,
          the following table sets forth the key considerations:

Quantitative Analysis
(amounts in 000's except per share amounts)  2006          2005          2004
Net income as reported                      87,171        71,905        62,447
Weighted average shares outstanding         98,359        99,125        100,000
Earnings per share as reported               0.89          0.73          0.62
Rollover error impact                          171        (2,169)        (2,793)
Adjusted net income                         87,342        69,736         59,654
% of misstatement to amounts reported        0.2%          3.0%           4.5%
Adjusted earnings per share                  0.89          0.70           0.60

          Years  prior  to  2004  were  deemed  to  be  less  important  in  our
          considerations as they were no longer included in our annual report on
          Form  10-K  and  given  the  nature  of  the   misstatements  and  its
          relationship  to  earnings,  would  not be  expected  to  result  in a
          conclusion  different than that reached for the years ended 2004, 2005
          and 2006.

          The following tables summarize the quantitative considerations for the
          respective  quarters (amounts in $000's except per share information).
          The rollover impact of the  misstatement was allocated to the quarters
          based on  pre-tax  earnings  for the  respective  quarters  given  the
          relationship to earnings:

          The concept of materiality can not be limited only to the quantitative
          considerations above, and the Company considered certain,  qualitative
          factors to be equally  relevant in our  consideration  of materiality.
          Those qualitative considerations are discussed below, and represent an
          important   part  of  our  overall   conclusion   as  to  whether  the
          misstatements   were  material  to  any  of  the  periods   presented.
          Qualitative  factors considered were the following (SAB 99 qualitative
          guidance shown in italics):

          o    Whether  the  misstatements  mask a change in  earnings  or other
               trends.  Per the analysis above, the misstatement does not change
               net  income  to  net  loss  in any  period  presented,  and  more
               importantly,  as this  adjustment  was  limited to income  taxes,
               there is no impact on operating  income,  expense ratios or other
               meaningful  measures  on which we would  expect  an  investor  or
               analysts would assess our financial results.  In addition,  these
               misstatements  do not result in material  adjustments to earnings
               per share (EPS) or the effective tax rate.
          o    Whether the  misstatement  arises from an item capable of precise
               measurement  or whether it arose from an estimate and, if so, the
               degree of imprecision inherent in the estimate. Due to the nature
               of the  misstatements  related to potential state tax liabilities
               for filing  positions  taken, the misstatement was not able to be
               measured  with  precise   measurement.   The  liability  recorded
               represents   management's   best  estimate  based  on  facts  and
               conditions  known to the  Company  at the time of the  respective
               filings.
          o    Whether the  misstatement  concerns a segment or other portion of
               the  registrant's  business that  has been identified  as playing


               significant role in the registrant's operations or profitability.
               The  misstatements  do not concern any particular  segment as the
               Company  operates in one segment as disclosed in the footnotes to
               the Company's financial statements.
          o    Whether the misstatement affects the registrant's compliance with
               regulatory  requirements  or  compliance  with loan  covenants or
               other contractual  requirements.  The Company is not aware of any
               such regulatory or contractual  requirements and did not have any
               debt outstanding during the periods presented.
          o    Whether   the   misstatement   has  the   effect  of   increasing
               management's   compensation   -  for   example,   by   satisfying
               requirements for the award of bonuses or other forms of incentive
               compensation.  The  Company  has not had any  material  forms  of
               incentive  compensation  for management that has been attached to
               or  derived  from  operating  results  and  therefore  management
               compensation was not affected by the misstatement.
          o    Whether the  misstatement  involves  concealment  of any unlawful
               transaction.  The  misstatement  does not  conceal  any  unlawful
               transaction.

          No  other   qualitative   considerations   were   identified   in  our
          consideration of materiality of the misstatements identified.

Misstatement analysis

Based on  consideration  of the qualitative and  quantitative  factors set forth
above,  the  Company  concluded  that the  impact  of the  misstatement  was not
material to any of the periods during the years ended December 31, 2004, 2005 or
2006 under the rollover  method  employed in evaluating  misstatements  in years
prior  to the  adoption  of SAB  108.  As a  result,  the  Company  applied  the
provisions  of SAB 108 and  recorded  an  adjustment  to 2006  opening  retained
earnings to reflect the liability as determined.
