Self-Driving Car Laws by State

The Regulatory Landscape

There is no single federal law governing autonomous vehicles in the United States. While NHTSA sets vehicle safety standards and collects incident reports, individual states determine whether and how autonomous vehicles may operate on their roads. As of 2025, over 30 states have enacted legislation or executive orders related to autonomous vehicles.

The approach varies dramatically. California has one of the most comprehensive regulatory frameworks, requiring permits for both testing and commercial deployment, along with detailed incident reporting. Arizona took an early permissive stance under executive order, attracting companies like Waymo and Uber to test there. Texas has minimal AV-specific regulation, operating under general traffic laws. Some states have no AV legislation at all.

NHTSA incident data covers 52 states and territories, with incidents concentrated in states where AV companies actively operate fleets or where consumer ADAS vehicles are most popular. The distribution of incidents reflects both regulatory openness and population density.

Key Regulatory Approaches

• Permit-based (e.g., California): Companies must obtain testing and/or deployment permits, submit regular reports, and comply with specific safety requirements. This approach provides the most data but can slow deployment.
• Executive order (e.g., Arizona): The governor authorizes AV operation without specific legislation. This allows faster deployment but with less regulatory structure.
• Legislation-based (e.g., Florida, Nevada): State legislatures have passed specific AV laws defining requirements for testing and deployment, insurance, and liability.
• No specific regulation (e.g., many states): AVs operate under existing traffic laws. This creates uncertainty for companies but doesn't explicitly prohibit operations.

Federal vs. State Authority

The federal government (through NHTSA) regulates vehicle design and safety standards, while states regulate vehicle registration, licensing, insurance, and traffic laws. This division means a vehicle can be federally compliant but may not be authorized to operate autonomously in a particular state. Congress has repeatedly attempted to pass comprehensive AV legislation (the AV START Act, SELF DRIVE Act) but none have become law as of early 2025.

This regulatory fragmentation creates challenges for AV companies seeking to scale nationally. A company that has permits and regulatory approval in California must navigate entirely different requirements to operate in Texas, Florida, or New York. Some industry leaders have called for federal preemption of state AV laws, while states argue they need to maintain local control over road safety.

Key State Profiles

California

California's DMV administers the most comprehensive AV testing and deployment program in the country. Companies must obtain permits for testing (with or without a safety driver), report all crashes and disengagements, and meet specific insurance requirements. The state's detailed reporting requirements mean California contributes more public AV safety data than any other state.

Arizona

Arizona attracted early AV testing through a business-friendly executive order in 2015. The state became home to Waymo's first commercial robotaxi service and was also where the fatal Uber self-driving car crash occurred in 2018. Arizona has since developed more structured regulations while maintaining its welcoming stance toward AV companies.

Texas

Texas has minimal AV-specific regulation, which has attracted companies like Nuro and Aurora for commercial deployment. The state's approach exemplifies the "permissionless innovation" philosophy — allowing technology to deploy and regulating only if problems emerge.

Florida

Florida was one of the earliest states to pass AV-specific legislation (2012) and has progressively expanded permissions. The state allows fully autonomous vehicles to operate on public roads without a human driver, making it one of the most permissive states for AV deployment.

Insurance Requirements

States that have enacted AV legislation typically include insurance requirements, though these vary significantly. Some require higher minimum liability coverage for autonomous vehicles than for conventional vehicles. For ADS commercial operators like Waymo, insurance requirements can run into millions of dollars per fleet. For more on how AV crashes affect insurance, see our AV insurance guide.

Liability and Insurance by State

State AV laws typically address liability and insurance requirements, though approaches vary widely. Some states require AV operators to carry higher minimum liability coverage. Others have created new insurance categories for autonomous vehicles. The liability question becomes especially complex when a crash crosses state lines or when a nationally deployed ADAS system (like Tesla Autopilot) behaves differently under different state traffic laws.

For ADS commercial operators like Waymo, state-specific insurance requirements can run into millions of dollars per fleet. The patchwork of state requirements adds compliance costs that may slow AV deployment in some regions. For more on how crashes affect coverage, see our AV insurance guide.

The Data-Regulation Connection

There's a clear correlation between regulatory frameworks and available safety data. States with comprehensive reporting requirements (California) provide far more transparency than states with minimal regulation (Texas). This creates an information asymmetry that makes it difficult to compare AV safety across states and to make informed policy decisions.

NHTSA's federal SGO reporting requirement partially addresses this gap by collecting incident data nationally, regardless of state-level reporting rules. For national statistical breakdowns, see our AV crash statistics page.
