Truck Size, Weight Limits Study Explored in DOT Session

May 9, 2013 By: Trucking News Staff Tags: News, Regulations, Safety

The U.S. Department of Transportation is inviting the public to provide input on May 29 about the upcoming Comprehensive Truck Size and Weight Limits Study (CTSW).

Map-21 Section 32801 requires the Department of Transportation (DOT) to complete a study that evaluates and compares the differences between trucks loaded at or below current federal truck size and weight limits to those operating in excess of those limits.

The study will produce findings on highway safety and truck crash frequency and severity and pavement and bridge infrastructure service life impacts. It will also probe the cost and effectiveness of enforcement and implications for the national transportation system, including the modal share of freight movements that would result if federal truck size and weight limits were to change.

The Public Outreach Session on May 29 will provide an opportunity to share feedback on the approach and methods DOT intends to use to complete the study. DOT will also solicit comments on “alternative truck configurations” to be evaluated in the study.

The meeting, which is free and open to the public, will be held from 12:30 to 4:30 p.m. at DOT headquarters, 1200 New Jersey Ave., SE, Washington, D.C. In addition webinar access is available for those unable to attend in person.
