Summary: Surface Transportation Extension Act of 2003 - Extends Federal highway, highway safety, motor carrier safety, and transit programs for six months, and authorizes appropriations, through March 31, 2004.

 Directs the Secretary of Transportation to: (1) apportion funds made available for Federal-aid highway programs under the Transportation Equity Act for the 21st Century (TEA-21) to each State according to the ratio of the State's FY 2003 obligation authority to the FY 2003 obligation authority for all States; and (2) ensure that each State is apportioned funds for the Interstate maintenance program, the National Highway System program, the bridge program, the surface transportation program, the congestion mitigation and air quality improvement program, the recreational trails program, the Appalachian development highway system program, and the minimum guarantee.

Sets forth provisions: (1) for reducing future apportionments, and for recovering funds not apportioned, under a law reauthorizing the Federal-aid highway program that is enacted after enactment of this Act; (2) prohibiting States from obligating any Federal-aid highway program funds after March 31, 2004, until the earlier of the date of enactment of a multi-year law reauthorizing such program or June 30 2004; and (3) directing the Secretary of Transportation, on the earlier of such enactment date or June 1, 2004, to distribute to each State any remaining amounts of obligation authority for Federal-aid highways and highway safety construction programs by allocation as provided in an Act making appropriations for the Department of Transportation for FY 2004

adjustments made pursuant to section 110(a)(2) of title 23, United 
States Code, to sums authorized to be appropriated from the Highway 
Trust Fund (other than the Mass Transit Account) to carry out each of 
the Federal-aid highway and highway safety construction programs (other 
than emergency relief) in fiscal year 2004 shall be deemed to be zero.
    (e) Sense of Congress on Adjustment to Align Highway Spending With 
Revenues.--It is the sense of Congress that, in any multiyear 
reauthorization of the Federal-aid highway program, the alignment of 
highway spending with revenues under section 251(b)(1)(B)(ii) of the 
Balanced Budget and Emergency Deficit Control Act of 1985 should be 
restructured to minimize year-to-year fluctuations in highway spending 
levels and to ensure the uniform enforcement of such levels.
