1969 DOT published a document for rear underride proposed rulemaking on the Federal Register on March 19, 1969, indicating that they “anticipated that the proposed Standard will be amended, after technical studies have been completed, to extend the requirement for underride protection to the sides of large vehicles.” https://annaleahmary.com/2016/03/side-guards-the-original-intent-of-nhtsa-rulemakers-in-the-1969-nprm-docket-no-1-11-notice-2/

2019 FMCSA Volpe Transportation Center Study Final Report Completed by February 2019 but not available publicly (as of 1/10/2020). Goals include — Despite three decades of international experience, the operational, cost-benefit, and regulatory aspects of requiring truck side guards in the United States has not been studied. This research project addresses this gap. Five key tasks are included in this project: (1) study interaction of a potential side guard with other truck parts and accessories (e.g., fuel tanks, fire extinguisher, exhaust system) and the implications for a new Federal Motor Carrier Safety Regulation; (2) investigate applicable international side guard standards; (3) perform a preliminary cost-benefit analysis of truck side guard deployment; (4) propose recommendations; and (5) propose means for voluntary adoption.: Study of Truck Side Guards to Reduce Pedestrian Fatalities
