Certification of Enforcement of Vehicle Size and Weight Laws

Section 141 of Title 23 U.S.C. requires an annual certification from each State in order to qualify for the next year’s apportionment of Federal-aid funds for highway construction and maintenance. Less frequent collection is, therefore, not appropriate. The information which each State is required to submit to the FHWA includes a signed, certifying statement attesting to the actual resources applied during the prior fiscal year to enforcement operations aimed at assuring compliance with commercial vehicle size and weight provisions. The submission also identifies State vehicle size and weight laws and regulations that recently have been proposed or enacted, and includes a data report on numbers of enforcement actions taken and sanctions imposed. Beginning in the 4th Quarter of FY 2005, FHWA activated its on-line website, allowing electronic submissions, thereby eliminating the compilation and submission of a paper document. All States submit their certification statements electronically. The vehicle size and weight data may be collected electronically by the States at fixed platform scales, or manually at portable and semi-portable scales. Weigh-in-motion (WIM) screening equipment is also employed to screen at speed in the roadway. WIM identifies vehicles potentially operating above allowable weight limits and is typically employed in conjunction with permanent scale operations located immediately down the road from the WIM site. This information is collected by the Federal Highway Administration in their VSW software application.
