DOT Lays Out Federal Rulemaking Plan for Autonomous Trucks

The U.S. Department of Transportation has released a comprehensive strategy for regulating automated vehicles that addresses long-standing questions about how driverless trucks will comply with federal motor carrier safety rules designed for human operators.

The Automated Vehicles National Strategy, published September 3, maps DOT priorities through fiscal year 2030 and clarifies which agencies will oversee different aspects of autonomous commercial vehicle deployment. While the document itself creates no new regulations, it provides the first detailed timeline for rulemakings that could enable coast-to-coast autonomous freight operations.

Why it matters

Autonomous trucking companies have operated in regulatory limbo for years, uncertain how existing driver-focused rules apply to vehicles with no one behind the wheel. This strategy signals federal intent to create a coherent regulatory framework rather than force-fit driverless technology into decades-old human-driver regulations—a shift that could accelerate commercial deployment timelines.

FMCSA to Rewrite Core Trucking Regulations

The Federal Motor Carrier Safety Administration is developing proposed regulations specifically addressing automated commercial motor vehicle operations, inspection, repair, and maintenance. Current safety regulations assume human drivers, creating ambiguity around commercial driver's licenses, hours-of-service limits, roadside inspections, and compliance responsibility when no person occupies the cab.

FMCSA's rulemaking, listed in the federal Unified Agenda for August 2026 publication, could amend regulations covering driver qualifications, drug and alcohol testing, driving requirements, vehicle components, and maintenance protocols. The strategy document provides no updated timeline or specifics on what the agency will propose.

FMCSA has solicited public input on autonomous truck regulations since 2018 and published its most recent advance notice of proposed rulemaking in 2023, according to details first reported by TruckingInfo.

Agency Roles and State Authority

The strategy delineates federal oversight responsibilities: NHTSA will regulate automated driving systems as vehicle equipment, including defect investigations and recalls. FMCSA will oversee motor carriers operating autonomous trucks. The Federal Highway Administration retains authority over infrastructure standards and truck size-and-weight rules. PHMSA will handle hazardous materials transportation by automated vehicles.

States and local governments keep traditional authority over licensing, traffic laws, and enforcement—one of the biggest obstacles for autonomous freight companies seeking multistate routes. DOT said it will encourage interstate consistency through voluntary coordination rather than federal preemption of state authority.

Infrastructure and Emergency Response

DOT plans to work with states on interoperable highway corridors enabling cross-border data exchange about road closures, work zones, and lane shifts. However, the department emphasized that automated vehicles must operate safely on existing infrastructure without requiring smart highway investments or vehicle-to-everything communications as deployment prerequisites.

FMCSA is developing emergency response procedures for automated commercial vehicles, addressing how first responders identify vehicle status, communicate with remote operators, disable automated systems, or move trucks without drivers. PHMSA is separately reviewing hazmat regulations around shipping papers, placarding, and cargo information access when no person is aboard.

NHTSA plans to develop the first objective performance standards for automated driving system competency, establishing minimum requirements before public road deployment, though specific standards remain years away.

These details were first reported by TruckingInfo.

Key Regulatory Gaps Remain

The strategy acknowledges that automated vehicle adoption will be gradual and that human-driven and autonomous vehicles will share roads indefinitely. DOT pledged to address workforce impacts from automation but offered few specifics on that effort.
