NHTSA Proposes Flexible Safety and Lighting Standards for Automated Vehicles

The National Highway Traffic Safety Administration (NHTSA) has proposed revisions to federal vehicle-safety requirements for vehicles designed to operate exclusively through automated driving systems. The rulemaking would update Federal Motor Vehicle Safety Standard (FMVSS) No. 108, which governs vehicle lighting, and adjust provisions that assume a human driver controls conventional vehicle functions. NHTSA’s stated aim is to address regulatory burdens and costs associated with equipment that may not serve the same purpose or provide the same safety benefits in vehicles without traditional manual controls, while retaining performance standards intended to protect road users.

The proposal includes changes involving manual-control provisions and headlamp testing, as well as the option of standardized cyan marker lamps to identify vehicles operating in automated-driving mode. It also proposes exemptions from selected requirements concerning turn signals, hazard lights, headlights, and driver-alert features. One example described in the source material is a “telltale” sound that alerts a human after a turn signal is engaged. These changes could affect vehicle architecture, lighting configurations, human-machine interfaces, testing plans, and compliance documentation. The source material does not specify the final text or the precise conditions under which each proposed exemption would apply, so affected organizations should consult the proposal itself before making engineering or investment decisions.

NHTSA Administrator Jonathan Morrison framed the proposal as an effort to balance innovation and safety: “As automotive technology continues to evolve, our safety standards must keep pace with innovation in ways that do not compromise public safety. These proposed updates address unnecessary regulatory burdens for vehicles built without traditional manual controls while establishing clear performance standards for automated vehicle marker lamps. By aligning our regulations with today’s technology, we are paving the way for safe innovation and setting clear rules of the road for automated vehicles.” The statement underscores that the agency is proposing both greater design flexibility and defined expectations for automated-vehicle marker lamps. For manufacturers and technology developers, the practical question is how those requirements may translate into vehicle-level safety cases, validation evidence, and production specifications.

The proposal is identified as Docket No. NHTSA-2026-1519. A 30-day public comment period is expected to begin after publication in the Federal Register, but the available signal does not provide a publication date. Suppliers and developers can review the proposed language and submit technical comments on system impacts, testing methods, and safety performance during the comment period. GovCon and business-development teams should treat this as regulatory intelligence rather than a procurement notice: it does not announce an award, solicitation, or funded acquisition. However, potential changes to compliance obligations may influence future vehicle-system requirements, supplier qualification, engineering work, and public-sector fleet planning. Teams should track the docket, coordinate regulatory and engineering review, and avoid locking specifications to assumptions that could change as the rulemaking proceeds.

• NHTSA is proposing changes for vehicles designed to operate exclusively through automated driving systems.
• The proposal would revise FMVSS No. 108, including provisions related to manual controls and headlamp testing.
• The agency proposes an optional standardized cyan automated-driving-system marker lamp with clear performance standards.
• Potential exemptions address selected requirements for turn signals, hazard lights, headlights, and driver-alert features.
• The source describes a turn-signal “telltale” sound as an example of a human alert that may not fit vehicles without traditional manual controls.
• The rulemaking is tracked under Docket No. NHTSA-2026-1519; a 30-day comment period begins after Federal Register publication, whose date is not provided in the signal.
• Manufacturers, lighting suppliers, and automated-driving-system developers can assess design, testing, and safety-performance effects and consider submitting technical comments.
• Procurement teams should distinguish this proposed rule from a solicitation or award and evaluate compliance implications before committing to vehicle-system specifications.
• NHTSA Administrator Jonathan Morrison said the updates are intended to reduce unnecessary burdens without compromising public safety.
