How Often Do Driverless Vehicles Have Accidents?

Driverless vehicles, once seen as futuristic, are now operating on public roads in cities across the U.S. In 2024, the National Highway Traffic Safety Administration (NHTSA) recorded 544 crashes involving driverless systems, averaging about 1.5 accidents per day. While the number of incidents has risen as companies like Waymo and Cruise expand their fleets, experts note that more vehicles in service naturally lead to higher crash totals.

The risk is not uniform; the rate of self-driving car accidents differs by manufacturer, technology level, and operating environment. Early studies suggest self-driving cars may reduce certain types of crashes, but sensor limitations, unpredictable road conditions, and human-automation interaction still create hazards. As the technology develops, regulators and safety advocates continue to push for stronger oversight to ensure these systems can handle real-world driving challenges.

Key facts on driverless vehicle accidents:

Understanding Self-Driving Vehicles

Self-driving technology has the potential to improve road safety, but accidents still happen. Like any collision, these incidents can cause injuries, deaths, and property damage, just like any traffic crash.

A challenge with crash data is how to define a “self-driving” vehicle. Researchers often use SAE’s six levels of driving automation:

ADAS (Advanced Driver Assistance Systems) covers Levels 1 and 2. These systems can help with tasks like steering or braking, but the driver must stay fully alert and in control. Most cars on the road today, like many Teslas, use ADAS.

ADS (Automated Driving Systems) covers Levels 3 to 5. These vehicles can handle some or all driving on their own, depending on the situation.

For purposes of this discussion, we’ll focus on ADS because it’s what most people mean when they talk about “driverless vehicles.”

The following table outlines commonly used definitions and terminology for different types of autonomous vehicles:

How Many Driverless Vehicle Accidents Have There Been?

Self-driving cars have been in the spotlight in recent years, often due to safety concerns and accidents. However, because the technology is new, full nationwide data is limited.

Data published by ConsumerAffairs shows that 508 accidents involved vehicles with ADS between July 2021 and December 15, 2023. These vehicles usually operate at automation levels 3 to 5, meaning they have advanced self-driving features and can run with or without a safety driver. Of the 508 crashes, 439 did not result in injuries.

California has some of the most detailed information available. According to Statista, there were 132 reported collisions involving autonomous vehicles in the state in 2022. Based on their estimates, this equals about 97 crashes for every 1,000 self-driving cars.

The state stands out in AV reporting because its Department of Motor Vehicles (DMV) runs a dedicated program for autonomous vehicles. The DMV issues permits to companies testing and operating AVs on public roads. While other states have passed laws on autonomous driving, this region remains a major hub for AV development thanks to many leading manufacturers and tech companies based there.

How Many Self-Driving Vehicle Accidents Are There Per Year?

It can be hard to track the exact number of crashes because the data changes each year. We reviewed NHTSA records on vehicles with Automated Driving Systems (ADS) from July 2021 to December 2024:

The number of ADS-related crashes has increased each year as more self-driving vehicles are being tested and used.

While 2024 saw a sharp increase in incidents, it’s important to consider the context. The number of autonomous vehicles on the road has grown as companies like Waymo and Tesla expand their fleets. Self-driving cars used by rideshare platforms such as Lyft and Uber have also become more common. With more vehicles in operation, the rise in reported crashes in 2024 was expected.

Still, safety remains a concern with driverless vehicles. As technology advances, regulations must also evolve to protect everyone on the road. Car accident attorneys help injured individuals handle the often complicated claims process.

Number Of Accidents Per Vehicle Company

Many companies are developing driverless vehicles. While fully autonomous models are not yet common, ADS incident data helps show how many crashes each company is involved in.

Number Of Incidents Involving ADS-Equipped Vehicles Per Company

The number of ADS-related crashes differs between companies. NHTSA data from July 2021 to April 2025, updated in May 2025, shows the following:

• Waymo LLC — 907
• Cruise LLC — 155
• General Motors, LLC — 149
• Transdev Alternative Services — 138
• Zoox, Inc. — 81

These companies reported the most incidents in the data, with Waymo having the highest number. Tesla does not appear on this list because its crashes are counted under ADAS, not ADS. However, since Tesla is one of the most well-known companies developing self-driving technology, it’s helpful to look at its numbers for context. During the same period, Tesla reported over 2,000 ADAS-related incidents, prompting questions about how many deaths Tesla has caused in connection with its self-driving technology.

The differences in crash numbers may reflect how many vehicles each company operates, where they run, and the safety measures they follow. However, since we don’t have full data on each company’s fleet size, it is not easy to make direct comparisons.

As companies continue developing self-driving technology, the benefits of fully automated automobiles become increasingly clear, offering exciting possibilities for the future of transportation. Still, safety remains a serious concern until the systems become fully dependable. If a crash involves a driverless car, injury attorneys can help injured individuals understand their legal options, sort out who may be responsible, and pursue compensation.

Key Risk Factors For Driverless Vehicle Accidents

Many believe self-driving cars could transform transportation. They may improve accessibility, reduce crashes, and make roads safer. Automation is also reshaping other areas of transportation, with new freight technologies transforming the trucking industry.

However, there are still concerns that these vehicles could also increase accidents. Some risks include:

• Sensor Limitations — Cameras, radar, and lidar may not work well in bad weather or poor lighting, making it harder to detect obstacles.
• Automation Complacency — Drivers might rely too much on automation and react too slowly when they need to take control.
• Cybersecurity Vulnerabilities — Self-driving cars could be vulnerable to hacking or unauthorized access.
• Environmental Challenges — Dangerous road conditions, worn-out signs, and unusual traffic signals can confuse the vehicle’s systems.
• Human-Machine Interaction — Autonomous vehicles may struggle to handle unpredictable behavior from other drivers, pedestrians, or cyclists.

While the technology continues to improve, these risks show why careful testing, strong regulations, and further development are still needed. A key goal is to build systems that can safely handle different roads, weather, and traffic situations.

Car accident lawyers can help you understand your situation and assist you in navigating the legal system if you need to file a claim for these incidents.

Who Regulates Self-Driving Car Safety?

The NHTSA regulates self-driving car safety on a federal level. Generally, it sets the vehicle and highway safety regulations under which self-driving cars would fall. Through measures like the Standing General Order requiring companies to report crash incidents involving automated systems, NHTSA maintains its authority to oversee and improve the safety of driverless vehicles. The agency has been actively developing policies related to emerging vehicle technologies, with a focus on:

• Safe development
• Testing
• Deployment

The agency also assists states in passing legislation when it comes to these types of vehicles. In fact, some states have already enacted their own regulation for automated vehicle development. In California, the DMV regulates autonomous vehicles. They issue permits to manufacturers for testing and deployment. They also allow driverless testing and testing with safety drivers.

Laws regarding autonomous vehicles may vary by state. The National Conference of State Legislatures (NCSL) has compiled information on the legislation enacted in each state. These regulations generally focus on testing, safety, and operation. While specific rules on product liability for autonomous vehicles are still limited, victims may still be able to pursue legal claims if a defect in the vehicle leads to an accident. In general, product liability may apply when there is:

• Design Defect — The design made the vehicle unsafe.
• Manufacturing Defect — There is a manufacturing error that made the vehicle hazardous.
• Failure to Warn — If the vehicle manufacturer failed to provide adequate instructions, it may lead to unsafe use.

For instance, how often sensors on driverless vehicles fail can play a critical role in determining who is liable after an accident. In such cases, consulting a product liability attorney may be advisable. If a product defect contributed to a driverless vehicle accident, a collision lawyer can help investigate the cause. This process may involve examining the manufacturing process, reviewing the components used, and consulting with industry experts.

What Is The Main Cause Of Self-Driving Car Accidents?

There isn’t just one cause. Most crashes happen because of both human mistakes and problems with the technology.

Self-driving cars use sensors, artificial intelligence, and lots of data to operate. However, even with this technology, accidents can happen if the system doesn’t see obstacles, makes the wrong decision, or struggles in complex situations. Human drivers can also cause problems if they rely too much on the system, misuse the controls, or get distracted.

For example, in one fatal Uber accident, the self-driving car didn’t recognize a pedestrian in time. The safety driver, who was supposed to step in if needed, was distracted and didn’t react. This event shows how accidents can happen when both the technology and the driver fail.

Because driverless car accidents often involve both technology failures and human mistakes, figuring out what caused the crash isn’t always simple. Personal injury lawyers can dig into the details, work with experts, and help uncover who may be legally responsible.

Are Self-Driving Cars Safer Than Human Drivers?

There isn’t enough research yet to say for sure if self-driving cars are safer than human drivers. However, early data from Waymo shows that driverless cars may have fewer crashes.

Waymo studied its fully autonomous ride-hailing service, where no human drives or controls the car. These vehicles use Waymo Driver, a Level 4 self-driving system. The study included over 7 million miles driven by the end of October 2023 in Phoenix, Los Angeles, and San Francisco.

The results showed:

• For crashes with injuries, Waymo’s self-driving cars had 0.6 crashes per million miles. Human drivers had 2.8 crashes per million miles.
• For crashes reported to police, Waymo had 2.1 crashes per million miles, while human drivers had 4.68 crashes per million miles.
• Overall, driverless cars had 80% fewer injury crashes and 55% fewer police-reported crashes compared to human drivers.

These numbers suggest that self-driving cars might be safer. At the same time, the study also explains that it’s hard to compare directly because:

• Self-driving cars operate in limited areas under strict rules.
• The vehicles used pre-mapped routes and went through a lot of testing in simulations.
• Real-world driving can be very different from controlled test conditions.

More research is needed to know for sure. For now, accidents can still happen, whether a human or a driverless car is “behind the wheel.”

Can Self-Driving Cars Ever Be 100% Safe?

Self-driving cars may never be completely safe. Making anything fully safe is very difficult. Research from the Insurance Institute for Highway Safety (IIHS) shows that even when safety is the main focus, driverless cars might only prevent about one-third of crashes.

The other two-thirds often happen because of speeding and other forms of reckless driving, which human drivers mostly cause. Even with automation, accidents can still occur due to system errors or the unpredictable actions of other drivers, pedestrians, or cyclists.

Mechanical problems, like tire blowouts or brake failures, can also lead to crashes, no matter who is driving. Because of these challenges, self-driving technology still has more work ahead. Until it can handle complex real-world situations, safety concerns will continue.

Who Is Liable In An Autonomous Vehicle (AV) Accident?

Liability in driverless car accidents depends on what caused the crash. Even with self-driving features, drivers must stay alert because no vehicle today is fully autonomous.

Many AVs still have safety drivers during testing. Fully driverless cars, like Waymo’s Level 4 vehicles, operate only in certain pre-mapped areas without human drivers or remote control. These systems rely on strict safety rules to operate on public roads.

When an accident happens, more than one party may be responsible. Possible liable parties include:

• The safety driver (if present)
• The manufacturer
• The system or software designer
• Parts or sensor makers
• Repair or maintenance providers

Accidents may involve system errors, defects, or human mistakes. Because these cases can be complicated, having legal guidance is important. Attorneys for car accidents can investigate the crash, review evidence, and work with experts to find out who is responsible.

Do I Need A Personal Injury Lawyer After An Accident With A Driverless Vehicle?

You can file a claim on your own, but accidents involving self-driving cars are often complicated. Figuring out who is responsible can be tricky, and without legal help, you might miss some of the losses you can claim. This may lead to a settlement that falls short of covering your full financial and medical needs after the accident.

Compensation may cover medical bills, lost wages, property damage, and pain and suffering. Medical costs can include emergency care, doctor visits, prescriptions, physical therapy, or chiropractic treatment, depending on your injuries.

It can be hard to calculate the damages victims may recover from a claim. A personal injury attorney can help identify all possible damages, fight for fair compensation, and connect you with medical providers to support your recovery.

How Much Will It Cost To Hire An Attorney For Driverless Car Accidents?

Most lawyers for personal injury cases, including ours, work on a contingency fee. You only pay attorney fees if your case wins. Other case-related costs, like court fees or expert witnesses, may still apply.

The lawyer takes a percentage of your settlement, which can vary depending on how complex the case is and whether it goes to trial. Some law firms cover certain costs upfront and deduct them later from your payout.

Every case is different, so it’s important to discuss fees during your initial consultation. Your injury lawyer will explain all costs before you decide to move forward.

What Should I Do If I’m Injured In A Driverless Car Crash?

If you’re involved in an accident with an autonomous vehicle, taking the proper steps right away can significantly impact any potential legal claim:

1. Prioritize Medical Attention — Get your injuries checked and evaluated. Seeing a doctor ensures proper treatment and documents both your medical expenses and the severity of your injuries. Car crash attorneys often highlight the importance of this step in supporting your claim.
2. Document Extensively — If possible, save any photos or videos you or others took at the scene, including damage to vehicles, road conditions, traffic signals, and visible injuries. Keep records of the autonomous vehicle’s make, model, and any identifying details about the operator or company.
3. Gather Information — Keep contact information you collected from any human operators, company representatives, witnesses, and police officers. Request a copy of the police report if you have not received one.
4. Preserve Evidence — Keep all medical records, repair estimates, and correspondence with insurance companies or autonomous vehicle operators. Lawyers who focus on accident claims can also assist in obtaining other pieces of evidence that are harder to get, such as traffic surveillance footage or company records.
5. Avoid Discussing Fault — Limit your statements about the accident to facts only, particularly when speaking with insurance representatives.
6. Consult with a Lawyer — Autonomous vehicle accidents involve complex questions of liability that may differ from conventional vehicle accidents. A personal injury attorney who understands this area can help protect your rights and guide you through the claims process.

Acting promptly and thoroughly documenting the incident can make a significant difference in resolving your case effectively.
