To make technical amendments to title 49, United States Code, as necessary to improve the Code.

HR 4523 makes technical corrections to Title 49 of the U.S. Code to improve clarity and consistency in legal references. It updates section citations throughout the code (e.g., adding "of this title" after specific sections) and corrects minor formatting errors in definitions and provisions related to direct loans, loan guarantees, and transportation funding. This bill directly affects government agencies and legal documents that reference Title 49, such as the Department of Transportation and federal financial regulations. It contains no substantive policy changes or new requirements - only administrative adjustments to the existing legal code.
