How Will NHTSA’s AV STEP Impact the Future of Autonomous Vehicles?

January 2, 2025

The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) has proposed a significant initiative aimed at enhancing the safety and transparency of Automated Driving Systems (ADS). This proposal, known as the ADS-Equipped Vehicle Safety, Transparency, and Evaluation Program (AV STEP), is a voluntary program designed to support the development and oversight of ADS-equipped vehicles. Signed on December 19, 2024, AV STEP aims to gather crucial data, streamline exemption processes, and build public trust in ADS technologies.

The Purpose and Goals of AV STEP

Enhancing Transparency and Safety

The primary goal of AV STEP is to enhance transparency and safety in the rapidly evolving field of ADS technology. By encouraging voluntary participation from motor vehicle manufacturers, ADS developers, fleet operators, and system integrators, NHTSA aims to gather comprehensive data on the performance and safety of ADS-equipped vehicles. This data will be instrumental in developing ADS-specific Federal Motor Vehicle Safety Standards (FMVSS) and ensuring that these vehicles operate safely on public roads.

NHTSA’s approach with AV STEP recognizes the necessity of robust data collection to inform regulatory measures. The comprehensive reporting structure envisioned under the program will provide insights into various operational parameters, incident reports, and the overall performance of autonomous vehicles in diverse environments. By establishing a framework where participants regularly share operational data, NHTSA aims to identify patterns, understand potential risks, and craft regulations that effectively address the unique challenges posed by ADS technology.

Streamlining Exemption Processes

Another key objective of AV STEP is to streamline the process by which participants can obtain FMVSS exemptions for their ADS-equipped vehicles. Currently, NHTSA permits ADS-equipped vehicles on public roads as long as they comply with applicable FMVSS. However, the agency also grants exemptions for vehicles that do not meet all FMVSS requirements but are tailored for full ADS operations. AV STEP aims to simplify this process, making it easier for participants to obtain the necessary exemptions and advance their ADS technologies.

This streamlined process is expected to reduce bureaucratic hurdles that can delay the deployment of cutting-edge ADS technologies. By offering a clearer, more efficient pathway to obtain exemptions, AV STEP supports innovation while maintaining a strong focus on safety. This balance is crucial for fostering an environment where companies feel encouraged to invest in ADS development, knowing that there is a supportive regulatory framework that recognizes and facilitates the unique requirements of autonomous driving systems.

Eligibility and Participation Requirements

Defining Eligible Vehicles

To participate in AV STEP, entities must meet specific eligibility requirements. The vehicles must be designed to operate without an attentive human driver, and the ADS must manage the entire dynamic driving task, including all real-time operational and tactical functions required for on-road driving. This ensures that only fully autonomous vehicles are included in the program, providing a clear focus on the most advanced ADS technologies.

By setting these stringent eligibility criteria, NHTSA underscores its commitment to advancing only those technologies that have the potential to operate safely without human intervention. The focus on fully autonomous capabilities highlights the agency’s intent to push the boundaries of current ADS technologies and gather data on the performance of vehicles that can truly operate independently. This approach is aimed at accelerating the development of higher-level automation technologies and ensuring that they meet stringent safety standards before broader deployment.

Classification of Participants

Participants in AV STEP are classified into two categories based on their reliance on “fallback personnel.” These personnel are trained to oversee the performance of ADS-operated vehicles in traffic and take control when necessary to prevent hazardous events. Vehicles with fallback personnel align with SAE International Levels 3, 4, and 5 of driving automation, which imply varying levels of ADS involvement with minimal or no human intervention. This classification helps NHTSA gather data on different levels of automation and their impact on safety.

The inclusion of fallback personnel as a criterion for classification is significant in understanding the nuances of various ADS levels. This categorization allows NHTSA to collect differentiated data on vehicles that might require human intervention under certain scenarios versus those designed for complete autonomy. By analyzing performance across these categories, the agency can better understand the operational challenges and safety implications at different automation levels, informing more precise and effective regulatory measures.

Reporting and Data Collection

Quarterly and Event-Triggered Reporting

Participation in AV STEP requires entities to report diverse operational information to NHTSA. This includes quarterly general reporting, event-triggered incident reporting, and updates on operational changes. The data collected ranges from specific locations where these vehicles operate to incidents of traffic safety law violations. This comprehensive reporting ensures that NHTSA has a detailed understanding of the performance and safety of ADS-equipped vehicles.

Quarterly reporting provides a regular touchpoint for monitoring the ongoing performance and compliance of ADS-equipped vehicles, while event-triggered reporting ensures that any significant incidents are promptly communicated to NHTSA. This dual approach enables the agency to maintain a real-time overview of ADS operations and quickly address any emerging safety concerns. The granularity of data collected through these reporting mechanisms is expected to enhance the overall understanding of ADS performance under varied conditions, contributing to more informed regulatory decisions.

Promoting Transparency and Public Trust

NHTSA intends to publish reports on AV STEP applications and participation to promote transparency and build public trust in ADS technologies. By making this information publicly available, NHTSA aims to demonstrate the safety and reliability of ADS-equipped vehicles, encouraging broader acceptance and adoption of these technologies. The program’s emphasis on transparency is crucial for gaining public trust and ensuring the successful integration of autonomous vehicles into the transportation system.

The publication of AV STEP data serves a dual purpose: it holds participants accountable for their safety claims and provides the public with critical information to understand the real-world performance of autonomous vehicles. Transparency in reporting is essential for dispelling myths and fears surrounding ADS technologies and fostering a more informed public discourse. This open approach aims to build confidence in autonomous vehicle safety, paving the way for wider acceptance and eventual mainstream adoption.

Historical Context and Regulatory Actions

Previous NHTSA Initiatives

NHTSA has a history of actions aimed at regulating autonomous vehicles and vehicles with advanced driver-assistance systems (ADAS). One notable example is the General Standing Order issued in June 2021, which requires monthly crash reports from manufacturers and operators of ADS-equipped vehicles, even if the automation technology was not engaged at the time of the crash. This data collection has been crucial for opening defect investigations into various ADS and ADAS-equipped vehicles.

The monthly crash report requirement has provided NHTSA with valuable insights into the real-world performance and potential safety issues associated with ADS technologies. By collecting data regardless of whether the automation system was active during an incident, NHTSA ensures a comprehensive understanding of all factors contributing to crashes. This initiative laid the groundwork for more targeted and effective regulatory measures aimed at improving the overall safety of ADS-equipped vehicles and addressing specific areas of concern identified through the data.

Recent Regulatory Amendments

In response to the evolving ADS technologies, NHTSA has recently amended regulations to accommodate the unique nature of these vehicles. For instance, a March 2022 final rule removed terms like “driver’s seat” and “steering wheel” from specific FMVSS. These changes reflect NHTSA’s commitment to adapting regulatory frameworks to the advancements in vehicle automation technology, ensuring that safety standards remain relevant and effective.

These regulatory amendments mark a significant shift in how NHTSA approaches vehicle safety standards, recognizing that traditional vehicle structures and roles are changing with the advent of ADS technologies. By updating the language and requirements in FMVSS, NHTSA has made it clear that it is willing to evolve alongside technological advancements. This adaptability is essential for ensuring that regulations do not become obsolete but instead continue to provide the necessary oversight and safety assurances as ADS technologies progress.
