When the Car Was Partly Driving Itself: Liability Questions Raised by Driver-Assistance Systems

Was the car helping to drive when the crash happened?

Drivers have it easy these days. Millions of vehicles come equipped with driver-assistance tech. Lane centering. Adaptive cruise control. Automatic emergency braking. Long trips are becoming way less taxing…

But they have also created a brand new problem.

Here’s the problem:

Who’s liable when a “semi-autonomous” car crashes? Suddenly, things get complicated. Real complicated. Driver? Manufacturer? Software?

The driver isn’t always the only one at fault anymore.

This manual covers the liability issues these technologies present – and what to do following car accident claims involving the technology activated.

Time to dive in!

What Does “Partly Driving Itself” Really Mean?

Most driver-assist features are what experts call Level 2 systems.

They can steer, brake and speed up on their own. But here’s the catch…

You are in control. Always. According to federal safety regulators, Level 2 systems require you to remain fully attentive at all times.

No these cars are NOT driverless. Not by any stretch. (Even though the name of the feature implies they are.)

Now comes the sticky part. If the system messes up and the driver fails to notice – who pays?

Think about it:

Crashes don’t last long. Seconds. While the car’s software is deciding what to do. Now Insurance companies are playing the blame game. If you know how to handle yourself after car accident situations, it could mean the difference between a denied claim or receiving the compensation you deserve. The quicker you can protect evidence after a crash. The stronger your injury claim is.

Who’s Liable When Driver-Assist Is On?

Liability is simple in a typical crash. Driver messed up. Their insurance company writes the check.

Crashes involving driver-assist systems can be unique. There may be multiple parties at fault… And that’s GREAT news if you were injured!

The Driver

In most cases, the driver will still carry some of the blame.

Why? Because they are legally required to monitor the road, keep their hands ready and intervene if necessary. Texting, nodding off or “over relying” on the system doesn’t absolve anyone of responsibility.

The Carmaker

This is where things get interesting.

A carmaker can be held responsible if the system:

Had a design flaw that caused (or worsened) the crash
Didn’t warn drivers clearly enough about its limits
Sold as smarter than it actually is
Let drivers switch it on in places it was never built for

These are called product liability claims. And they’re growing every year.

Other Parties

Don’t forget about others. The body shop that installed a sensor improperly. The software provider. Another negligent driver. Any one could be partially at fault.

That’s why these cases need a careful look at every single piece of evidence.

The Verdict That Changed The Game

Want to see how this plays out in real life?

Tesla’s Enhanced Autopilot was involved in a fatal crash in Key Largo, Florida in 2019. While using Autopilot, a driver leaned down to pick up his phone he dropped. The vehicle accelerated through a stop sign at approximately 62 mph before crashing into a parked SUV – killing a 22-year-old woman and severely injuring her boyfriend.

Tesla argued the driver was the only one to blame.

The jury didn’t buy it.

In August 2025, jurors found Tesla 33% responsible for the crash. The total damages amounted to approximately $243 million. A federal judge upheld the jury verdict in February 2026, though Tesla plans to appeal the ruling.

Here’s why that matters:

The driver was obviously negligent. Yet the automaker was STILL partially blamed. That shows how a distracted driver doesn’t necessarily absolve the tech.

Why These Systems Fall Short

Driver-assist systems are only as safe as the safeguards built around them.

The Insurance Institute for Highway Safety (IIHS) evaluated safeguard systems built into partial automation technology from nine vehicle manufacturers. Only 1 of 14 systems received an “acceptable” rating from the IIHS. Eleven were rated poor.

That’s a big deal.

Some systems don’t adequately verify that the driver is looking at the road. Some systems’ alerts are too delayed to effectively catch a distracted driver’s attention. Some systems don’t turn themselves off if the seat belt is unbuckled.

Most drivers don’t realise any of this when they buy the car.

If a system is easy to abuse, that vulnerability can become a central issue in a liability lawsuit.

What To Do After Car Accident: 5x Steps

Were you involved in an accident that driver-assist may have contributed to? Actions you take during the first couple days can mean everything. Follow along…

Get Medical Help First

Your health is your number one priority. Get checked out, even if you think you are ok. Some injuries (i.e. whiplash, concussions) may not show up immediately. Additionally, it creates a paper trail.

Document Everything

Photograph the vehicles, road, traffic signs and your injuries. Get contact information from witnesses. Next, write down your recollection of events while they are fresh in your mind:

Was the other car’s driver-assist switched on?
Did the car brake, swerve or speed up on its own?
Did anyone hear warning beeps or alerts?

Protect The Vehicle Data

This is the big one.

Contemporary automobiles are logging data: speed, braking, steering input, etc., as well as whether driver-assist was engaged. Automakers are also required to report certain accidents to federal regulators if a Level 2 system was operating within 30 seconds of the crash.

However that data can be lost if the car is serviced, sold or scrapped. Send a preservation letter ASAP so nobody deletes it.

Be Careful With Insurance Adjusters

Insurance adjusters may try to settle quickly… Even before the police know there was a tech involved. Never provide a recorded statement or sign anything until you understand all your options.

Talk To An Experienced Attorney

Automobile manufacturers often have teams of lawyers defending driver-assist claims. A lawyer who specializes in these cases will investigate the facts, identify every party at fault and advocate on your behalf.

Putting It All Together

Self-driving cars aren’t going anywhere. Unfortunately, they haven’t made crash cases easier. Quite the opposite, they’ve made them much more complex.
