As the U.S. Department of Transportation's Comprehensive Truck Size and Weight (CTS&W) Study was nearing completion, the Western Governors' Association (WGA) asked the U.S. DOT to analyze another illustrative truck size and weight scenario in addition to the scenarios already included in the study. The "Western Uniformity Scenario" requested by WGA would assess impacts of lifting the LCV freeze and allowing harmonized LCV weights, dimensions, and routes among only those Western States that currently allow LCVs. U.S. DOT findings and recommendations are detailed within this document.
