The law around autonomous vehicles is a mess of confusion, and it’s tough for people and companies to know their rights and duties. California, always at the front of car tech, keeps changing its AV rules, and the new standards often catch even insiders by surprise.
Key Takeaways
- California’s DMV issues the permits for AV testing and deployment, with separate rules for cars with and without a safety driver.
- In an AV crash, liability often comes down to whether the car was in autonomous mode and if a human driver had a chance to intervene.
- The California Public Utilities Commission (CPUC) controls AV passenger services, and you need their specific permit to run a commercial robotaxi.
- There’s no big federal law like the AV START Act yet, so states like California are making the rules for everyone else to follow.
Myth 1: Autonomous Vehicles Are Fully Driverless and Require No Human Oversight
A lot of people think ‘autonomous’ means the car drives itself and everyone inside is just a passenger with no responsibilities. That’s just wrong. The reality on the ground, especially under California’s rules, is much more complicated. While the goal is full autonomy, the actual laws and operating permits require a human to be involved. The California Department of Motor Vehicles (DMV) has different classifications for autonomy levels and how the tech gets rolled out. For example, the permits for testing AVs with a safety driver are totally different from the permits for true driverless deployment. Even as we head into 2026, many of the cars you see on the road have a permit that requires a human safety operator who can grab the wheel at a moment’s notice. In fact, under the California Code of Regulations (Title 13, Division 1, Chapter 1, Article 3.8, Section 227.06), a company that wants a driverless testing permit has to prove the car is safe on its own *and* provide a remote operator who monitors the vehicle. This remote operator, even though they aren’t in the car, is a human in the loop, which blows up the idea that these things operate with zero human oversight.
Myth 2: If an Autonomous Vehicle Causes an Accident, the Manufacturer Is Always Liable
It feels logical: if the robot car crashes, you sue the company that built it. But liability in an AV accident is rarely that simple. Product liability is definitely a big part of it, especially if you can show a defect in the system, but other people can share the blame. What if a human driver yanks the wheel from the system or just ignores a clear warning to take control? California’s courts, when looking at personal injury claims, will dig into every detail of what led to the crash. If a car is at SAE Level 2 or 3 (partial automation), the human is still expected to be paying attention and ready to act. A report from the National Highway Traffic Safety Administration (NHTSA) on these systems talks about shared responsibility, pointing out that “the human driver is not a passive occupant” in many automated modes. In a crash on the 101 Freeway near downtown L.A., investigators are going to pull the data logs, see if the AV mode was on, check if it worked as promised, and determine if the human driver did something stupid. Figuring out who pays isn’t just about suing the car company. It means a deep dive into data, driver behavior, and system performance.
Were you in a car accident?
Insurance adjusters are trained to settle fast and pay less. Most car accident victims leave an average of $32,000 on the table.
Myth 3: Autonomous Vehicles Are Legal for Commercial Passenger Transport Everywhere in California
The idea of calling a driverless taxi is exciting, but turning that into a real business is a slow-moving, heavily regulated process. Some companies do have permits to carry passengers, but it’s not a free-for-all across the state. The California Public Utilities Commission (CPUC) is the main agency regulating AV passenger services, and its authority is separate from the DMV. To run a commercial service, a company needs a specific CPUC permit, and there are different kinds for services that charge a fare versus ones that are part of a free “driverless pilot” program. Say a company wants to run a driverless ride-hailing service in San Francisco, shuttling people from Fisherman’s Wharf to the Financial District. It must have a specific CPUC permit for autonomous vehicle passenger service. Getting one means submitting tough safety plans, carrying heavy-duty insurance, and filing constant reports. A DMV permit for driverless testing doesn’t give you the right to run a business. The CPUC’s own regulations, found in General Order 176, set the entire framework for these services to keep the public safe. Without that specific CPUC approval, offering rides for hire in an AV is illegal.
Myth 4: Federal Law Has Already Standardized Autonomous Vehicle Regulations Across the U.S.
A single, national set of rules for AVs would be great for carmakers and drivers, but it’s not happening anytime soon. Congress has made some attempts with legislation like the AV START Act, but no complete federal law has actually passed to standardize rules across the country. This means states like California are left to create and enforce their own. This patchwork of regulations is a real problem for companies trying to operate nationwide, since an AV that’s perfectly legal in Arizona could be banned in California. With no federal law taking precedence, the regulations from California’s DMV and CPUC are the final word within state lines. According to the National Conference of State Legislatures (NCSL), states have gone in all sorts of directions, creating a messy legal map. This is why manufacturers invest so much time and money complying with California’s rules, the state often sets the trends for the rest of the country.
Myth 5: Autonomous Vehicle Technology Eliminates All Human Error
AVs are built to reduce the number of accidents caused by people, but they won’t stop crashes altogether. Blaming every incident on a human driver ignores the reality of software bugs, sensor limits, and weird things that happen on the road. An AV won’t get distracted by a text message or drive drunk, but it can run into a situation its programmers never thought of. A vehicle’s sensors could be blinded by thick fog, or its AI might misread a damaged traffic signal. In a collision on a busy street in downtown Sacramento, an investigation could find that no person was at fault, but the autonomous system simply failed to react when a pedestrian unpredictably darted into traffic. Plus, the human element is never truly gone. Programmers can make mistakes, and maintenance can be skipped. The real promise of AVs is a huge drop in accident rates, not getting rid of them entirely. Believing they are infallible is a dangerous oversimplification that leads to complacency and bad legal arguments. The fast-changing field of autonomous vehicle law in California is complex. If you’re involved in an AV incident, you need experienced help to get through it.
What is the difference between an autonomous vehicle testing permit and a deployment permit in California?
A testing permit lets manufacturers run their AVs on public roads, almost always with a human safety driver inside. A deployment permit, which you can read about on the California DMV website, is for the next stage: it allows for truly driverless operations and even commercial service, but only after passing much stricter safety and operational hurdles.
Who is liable if an autonomous vehicle operating in California causes an accident with no human intervention?
If an AV in full autonomous mode causes a crash, liability often points toward the manufacturer based on product liability law, the argument being the system was defective. That said, every case is unique and will be decided by its specific facts.
Can I use my personal autonomous vehicle for ride-sharing services in California?
No. To operate an AV for commercial ride-sharing, you need special permits from the California Public Utilities Commission (CPUC), which are separate from any DMV permits. A personal vehicle almost certainly won’t meet the CPUC’s strict commercial and insurance requirements.
Does California have specific laws regarding cybersecurity for autonomous vehicles?
California’s AV regulations focus mostly on operational safety. But because these cars are so connected, cybersecurity is a massive concern. The DMV requires manufacturers to explain how they handle cyber risks in their safety plans, even though a specific law aimed only at AV cybersecurity is still in the works.
What is the role of the California Highway Patrol (CHP) in autonomous vehicle incidents?
The California Highway Patrol (CHP) investigates AV crashes just like any other collision. They secure the scene, gather evidence, and write the official accident report. That report becomes a critical piece of evidence for determining fault and liability in any legal case that follows.
