Legal Framework for State Regulation of Autonomous Vehicles

Michigan occupies a unique position in the autonomous vehicle regulatory landscape. As the historic center of the American automotive industry and home to major manufacturers, technology companies, and research institutions developing autonomous driving technology, the state has both a strong economic interest in fostering innovation and a responsibility to protect public safety. Michigan was among the first states to enact legislation specifically addressing autonomous vehicles, with laws dating back to 2013 that authorize the testing and operation of automated vehicles on public roads.

The regulatory framework for autonomous vehicles exists at the intersection of federal and state authority. The National Highway Traffic Safety Administration (NHTSA) has historically regulated vehicle safety through the Federal Motor Vehicle Safety Standards (FMVSS), which establish performance requirements for vehicle design and equipment. States have traditionally regulated the operation of vehicles, including driver licensing, traffic laws, insurance requirements, and registration. The emergence of vehicles that can operate without a human driver challenges this framework, as the distinction between vehicle design and vehicle operation blurs when the vehicle itself performs driving functions.

The federal-state division of regulatory authority over autonomous vehicles is governed by the National Traffic and Motor Vehicle Safety Act, which establishes NHTSA's authority to set safety standards for motor vehicles and preempts conflicting state standards related to vehicle performance. However, the Act's savings clause preserves state authority over vehicle operations, and NHTSA has repeatedly stated that it does not intend to preempt state authority over autonomous vehicle operations, registration, and insurance. The opinion concludes that Michigan retains broad authority to regulate the operational aspects of autonomous vehicles, including the conditions under which they may operate on public roads, the requirements for human oversight, and the insurance and liability frameworks that apply.

The liability framework for autonomous vehicle accidents presents novel legal questions. Under traditional negligence principles, liability for a vehicle accident typically falls on the driver who failed to exercise reasonable care. When a vehicle operates autonomously, the concept of driver negligence becomes less relevant, and attention shifts to the manufacturer, the software developer, and the entity that deployed the vehicle. Michigan's product liability framework, governed by MCL 600.2945 et seq., provides a cause of action for injuries caused by defective products, including design defects, manufacturing defects, and failure to warn. The opinion analyzes how these theories apply to autonomous vehicles, concluding that manufacturers may be held liable for accidents caused by defects in the automated driving system, including software errors, sensor failures, and inadequate responses to foreseeable road conditions.

Michigan's no-fault insurance system adds complexity. Under the no-fault law, vehicle owners are required to carry personal injury protection (PIP) insurance that covers medical expenses and lost wages regardless of fault. The question is how no-fault principles apply when the vehicle has no driver, or when the entity that deploys the vehicle is different from the registered owner. The opinion recommends legislative clarification to address these scenarios, including the establishment of clear requirements for which entity must carry no-fault insurance when a vehicle is operated autonomously by a fleet operator rather than an individual owner.

Data privacy is an emerging concern in the autonomous vehicle context. Self-driving vehicles generate enormous quantities of data, including detailed records of vehicle location, occupant behavior, driving patterns, and the vehicle's interactions with its environment. This data has significant value for law enforcement, insurance companies, and commercial entities, but its collection and use raise substantial privacy concerns. The opinion recommends that the legislature enact specific data privacy protections for autonomous vehicle data, including limitations on collection, use, and disclosure, and requirements for notice and consent.

Michigan has broad authority to regulate the operation, deployment, and insurance of autonomous vehicles, subject to federal preemption of vehicle safety standards. The state's existing statutory framework provides a foundation for autonomous vehicle regulation but requires legislative updates to address liability allocation, no-fault insurance applicability, and data privacy protections. The state should continue to balance its interest in fostering automotive innovation with its obligation to protect public safety and privacy.

This opinion guides legislators, regulators, manufacturers, and fleet operators in navigating Michigan's autonomous vehicle regulatory landscape. Manufacturers and technology companies deploying autonomous vehicles in Michigan should ensure compliance with state operational requirements and should carry appropriate insurance. Personal injury attorneys handling autonomous vehicle accident cases should consider product liability theories in addition to traditional negligence claims. Privacy advocates and policymakers should push for comprehensive data privacy protections specific to the autonomous vehicle context. The opinion also informs other states that are developing their own autonomous vehicle regulatory frameworks.
