Self-Driving Car Accident: What Drivers and Pedestrians Should Know

September 4, 2025 by Brad Johnson

Self-driving cars are becoming more common on roads across Arizona, especially in Phoenix. With companies like Waymo testing and operating autonomous vehicles in the area, more people are wondering what happens if you are involved in a crash with a self-driving car. 

This blog will walk you through the different types of autonomous vehicles, how to spot them, what to do after an accident, and who might be liable. We will also discuss some of the laws in place for self-driving cars at the local, state, and federal levels.

Types of Autonomous Vehicles on the Road

There are two main categories of autonomous vehicles you may encounter. 

1. Cars with Driver-Assist 

The first is a car with a driver using autopilot or an advanced driver-assist system. These vehicles still require a human behind the wheel, even if the car is handling most of the driving tasks. Popular systems like Tesla’s Autopilot fall into this category. The driver is expected to be alert and ready to take over if needed.

2. Fully Autonomous Vehicles

The second type is a fully autonomous, self-driving vehicle, which may operate with no human driver at all. These cars use advanced sensors, cameras, and computers to drive themselves and often look different from regular vehicles. Waymo and Cruise, for example, operate fleets of driverless cars that transport passengers in Phoenix and other cities.

How to Identify a Self-Driving Car

Spotting a self-driving car is getting easier, especially in areas like Phoenix where Waymo has already gained traction. Waymo vehicles were initially Chrysler Pacificas, but have all been replaced by Jaguar I-PACE SUVs. What sets them apart from other cars is their spinning lidar sensors on the roof. These vehicles often have branding or company logos, and the front seat is usually empty.

Cars using driver-assist features might be harder to identify because they look like regular cars. Any Tesla vehicle may be using Autopilot, but unless you can see the driver’s hands off the wheel, you might not know for sure.

Common Concerns About Self-Driving Cars in Phoenix

Phoenix has become a hub for autonomous vehicle testing because of its wide streets, sunny weather, and supportive local laws. However, some residents are concerned about safety, as there have been reports of self-driving cars blocking traffic, making sudden stops, or failing to yield to pedestrians. Others worry about how these vehicles interact with traditional drivers who may not understand how self-driving cars behave.

How Common Are Autonomous Vehicle Accidents?

While self-driving cars are involved in fewer accidents overall compared to human drivers, crashes do happen. According to public reports, most autonomous vehicle accidents are minor and often occur at low speeds. However, high-profile incidents, including some with injuries and even fatalities, have made headlines. As more self-driving cars take to the streets, the number of these incidents may rise, though many experts hope technology will make roads safer in the long run.

Who Is Liable If a Self-Driving Vehicle Causes a Crash?

Determining who is responsible after a crash involving an autonomous vehicle can be complicated. In many cases, liability depends on the type of vehicle, the circumstances of the accident, and the technology involved.

If the car was using a driver-assist system like Autopilot, the human driver may still be held responsible, especially if they were not paying attention or failed to take control when needed. These systems are designed to assist, not replace, a human driver.

With fully autonomous vehicles, the answer may be different. If a driverless car is at fault, the company that owns and operates the vehicle, such as Waymo or Cruise, could be held liable. In some cases, the manufacturer of the self-driving technology or the car itself may also be responsible if a technical defect caused the crash.

What Should You Do If You Crash with an Autonomous Vehicle?

After you are involved in an accident with a self-driving car, it is important to gather as much information as possible to help determine liability.

If You Are the Driver

When you are driving another car and are involved in a collision with a self-driving vehicle, stay calm and follow the usual steps after a crash. 

  1. Seek medical attention
  2. Move your vehicle to a safe place if you can. 
  3. Call the police to report the accident
  4. Make sure to exchange insurance and contact information with the other party, even if the self-driving car does not have a traditional driver. 
  5. Look for information inside the vehicle or contact the company that owns it.

Most importantly, gather evidence. Take photos of the scene, the vehicles, and any visible injuries. Write down details about what happened, and try to get witness statements if possible. It can also help to note if the self-driving car had any company markings or cameras.

If You Are a Pedestrian

If you are hit by an autonomous vehicle while walking or biking, seek medical attention right away. Even if you do not feel hurt, some injuries may not show up immediately. Try to get the vehicle’s license plate and any identifying company information. If possible, take photos and get contact details from witnesses. Report the accident to the police and contact a personal injury attorney who understands autonomous vehicle cases.

What Are the Laws for Self-Driving Vehicles?

Local Laws in Phoenix

Phoenix has welcomed self-driving car testing, allowing companies to operate autonomous vehicles on public streets. Local laws often focus on safety requirements, reporting accidents, and notifying authorities about autonomous testing.

Arizona State Laws

Arizona has some of the most relaxed regulations for self-driving vehicles in the country. The state allows both testing and commercial use of autonomous vehicles without a driver present, as long as the company meets safety and insurance requirements. After a fatal crash involving an autonomous Uber in Tempe, Arizona added more rules for safety reporting but still encourages innovation in this field.

Federal Laws in the United States

There is currently no single federal law covering all aspects of autonomous vehicles. The National Highway Traffic Safety Administration (NHTSA) provides guidelines and monitors safety, but states like Arizona make most decisions about how self-driving cars operate. Congress continues to debate new laws to address the unique challenges posed by these vehicles.

Conclusion

Being in an accident with a self-driving car can be confusing and stressful, but knowing what to do can help you protect your rights. Whether you are a driver or a pedestrian, gathering information and seeking legal advice is important. As technology evolves, the laws and liability rules around autonomous vehicles will continue to change. Stay informed and reach out to a car accident attorney if you have questions about your situation.
