DOT/FMCSA RIN: 2126-AC49 Publication ID: Spring 2024 
Title: Heavy Vehicle Automatic Emergency Braking 
Abstract:

This joint rulemaking of the National Highway Traffic Safety Administration (NHTSA) and Federal Motor Carrier administration (FMCSA) will finalize the proposal to require and/or standardize equipment performance for automatic emergency braking (AEB) systems on heavy trucks (2127-AM36). The rulemaking is expected to establish performance standards and motor carrier maintenance requirements for AEB systems on heavy trucks and accompanying test procedures for measuring the performance of the AEB systems in NHTSA compliance testing. NHTSA and FMCSA engaged in a national outreach, educational, and awareness campaign, and data collection analysis which included the development of training materials for fleets, drivers, and maintenance personnel related to AEB technology and return-on-investment (ROI) guides; educational videos on ADAS braking, steering, warning, and monitoring technologies; a web-based Tech-Celerate Now (TCN) ADAS-specific ROI calculator; and a program website to host the training materials. Planning is underway for the second phase of the TCN program, which includes an expanded national outreach and education campaign, additional research into the barriers to ADAS adoption by motor carriers, and evaluation of the outreach campaign.
