The National Highway Traffic Safety Administration (NHTSA) has announced that it will not enforce the compliance of specific bus safety rules, known as the Bus Rollover Structural Integrity final rule, until March 20, 2025. These rules require buses to pass a rollover test to ensure passenger protection, and they were supposed to take effect on December 30, 2024. However, due to a regulatory review ordered by the President, NHTSA is allowing time for further examination to ensure the rules align with legal and policy standards.

The National Highway Traffic Safety Administration and the Department of Transportation issued a correction notice related to a previous document published on December 21, 2020. The correction changes the date in the document from "January 20, 2021" to "January 21, 2021," which was originally on page 83143 in the DATES section. This correction ensures the information about applicability of safety test procedures for certifying manufacturers is accurate.

The National Highway Traffic Safety Administration (NHTSA), part of the Department of Transportation, announced the denial of a petition to investigate a recall of Tesla vehicles over alleged sudden unintended acceleration (SUA). The petitioner, Mr. Brian Sparks, had claimed a defect caused these vehicles to accelerate unexpectedly, posing a safety risk. However, after extensive analysis of data from Tesla and crash incidents, NHTSA found that the cause of the alleged SUA incidents was most likely driver error, specifically pedal misapplication. The agency found no evidence of a defect in Tesla's motor, brake systems, or vehicle design that would justify a vehicle recall.

The National Highway Traffic Safety Administration (NHTSA) proposes a voluntary program called the ADS-equipped Vehicle Safety, Transparency, and Evaluation Program (AV STEP) for vehicles with automated driving systems (ADS). The program aims to review and oversee these vehicles, focusing on safety and public transparency. Participants can apply to perform specific operations or seek exemptions from certain safety standards. The program is designed to help NHTSA monitor the safe development of ADS while collecting data that could inform future safety standards.

The National Highway Traffic Safety Administration (NHTSA) is seeking public comments about its plan to revise an approved information collection on vehicle safety features. The goal is to provide consumers with safety info, including crash avoidance technologies and safety features of different vehicle models. This effort involves collecting data annually from about 21 vehicle manufacturers regarding 600 vehicle models, and the feedback will help improve consumer safety information on websites and labels. Public comments on the proposed information collection will be accepted until March 3, 2025.

The National Highway Traffic Safety Administration (NHTSA) has denied a petition from Aldelberto A. Cordova requesting an investigation into an alleged defect in the 2023 Mercedes-Benz GLC300's 48-volt system, which reportedly caused warning lights to illuminate and led to starting issues. After reviewing the petition and information from Mercedes-Benz, NHTSA concluded that the problems may be linked to a software error in a different component, the Central Powertrain Controller (CPC), which is already being addressed through a service campaign by Mercedes-Benz. NHTSA found no grounds for a safety defect investigation at this time, but will continue to monitor any new safety information.

The National Highway Traffic Safety Administration (NHTSA) is seeking approval from the Office of Management and Budget (OMB) for a new study to collect data on vehicle occupant body size, shape, posture, and motion. This research aims to improve occupant safety by developing new human body models and crash test dummies that better reflect current population characteristics. The study will involve recruiting 300 participants for in-lab measurements and 100 for in-vehicle studies and is focused on addressing gaps in data, particularly for female drivers and individuals with high body mass. Public comments are invited on the necessity, effectiveness, and potential improvements of this proposed information collection.

The National Highway Traffic Safety Administration (NHTSA), part of the Department of Transportation, announced an extension of the comment period for a proposed rule about the safety of Automated Driving Systems (ADS). Originally ending on February 1, 2021, the new deadline for public comments is April 1, 2021. This extension was granted in response to a request from Venable LLC on behalf of various organizations, which needed more time to analyze and discuss the technical and policy questions raised by the proposal. The purpose is to gather detailed input to help shape the safety framework for these driving systems.

The National Highway Traffic Safety Administration (NHTSA) wants to collect public opinions about their plan to redesign the 5-Star Safety Ratings on car window stickers. They will conduct market research that includes interviews and surveys to get feedback on how to make these labels clearer and more helpful for consumers when buying cars. This effort is part of the requirements of the 2015 Fixing America's Surface Transportation Act. People can submit comments on this proposed information collection by May 6, 2025, through various methods like the Federal eRulemaking Portal or mailing the Department of Transportation.

The National Highway Traffic Safety Administration (NHTSA) has denied petitions requesting changes to the rules for adaptive driving beam (ADB) headlighting systems in vehicles. These petitions followed a final rule issued on February 22, 2022, that updated the Federal Motor Vehicle Safety Standard to allow for the certification of ADB headlamps in the U.S. Despite industry concerns about technical complexities, testing standards, and the desire for more flexibility in the rules, NHTSA maintained its position that the existing standards balance safety with performance. The agency emphasized that ADB systems must meet both vehicle-level and component-level requirements to ensure they improve visibility without causing excessive glare to other drivers.
