Comprehensive Truck Size and Weight Limits Study – Volume 1: Technical Reports Summary

This document is organized into three chapters. Chapter 1 describes current truck size and weight regulations in the United States, Mexico, Canada, the European Union, and Australia. Chapter 2 discusses the technical scope and methodology used in assessing the impacts of trucks operating above current Federal size and weight limits compared to the impacts associated with trucks operating at or below current Federal limits. In this Chapter, the impacts that changes to U.S. Federal truck size and weight limits may be expected to have are assessed, including: 1) Shifts in truck types, roadways, and modes used; 2) Highway safety (truck crash rates, vehicle performance, and violation patterns); 3) Pavement service life; 4) Bridge performance; and 5) Enforcement program delivery and effectiveness. It also discusses the approaches used to encourage public input and provides an overview of the study review process, including a peer review by the National Academy of Sciences, ongoing internal U.S. Department of Transportation reviews, and a comprehensive examination of prior truck size and weight studies in the desk scans (literature searches). These prior studies form the foundation and provide a guide for the current study. Finally, Chapter 3 summarizes the analytical results of each of the five technical study areas noted above. It includes information on the data and models used, the assumptions that were applied to each study area, and the limitations encountered during the analysis.
