How Automatic Emergency Braking Could Affect Your Car Accident Claim in South Carolina
Last Updated on July 29, 2025
You’re doing everything right. You’re focused, not speeding, and keeping a safe distance, then suddenly, a car ahead stops. Your vehicle jerks forward and slams the brakes for you. That’s automatic emergency braking (AEB) kicking in.
If your car reacted before you did, or didn’t react at all, you’re not alone. More South Carolina drivers are now finding themselves dealing with car accidents where auto emergency braking played a role, whether it helped or made things more complicated.
At the Law Office of Lori Murray, we’ve seen firsthand how confusing these cases can be, especially when insurers start pointing fingers at the technology instead of the facts. If you’re wondering how this tech affects your accident claim, or whether it could be used against you, let’s break it down together.
What Is Automatic Emergency Braking (AEB)?
A Quick Breakdown Without the Tech Jargon
Automatic emergency braking is a safety system that applies your brakes when a crash seems likely. Think of it like a backup plan; sensors on the car detect an obstacle and try to stop the vehicle before you even react. According to the National Highway Traffic Safety Administration, AEB is designed to help reduce front-end crashes but isn’t meant to replace the driver.
It’s now standard in many newer models, especially those sold after 2022. According to the Insurance Institute for Highway Safety, 20 of the top automakers that cover 90% of the U.S. new car market have agreed to make AEB standard on:
- Light-duty vehicles by September 1, 2022
- Larger trucks by September 1, 2025
But not every car has it, and even when they do, it doesn’t always work the way you’d expect.
Why It Matters in a Crash
AEB can help reduce the force of a crash, or sometimes prevent one altogether. But it isn’t perfect. It might miss motorcycles. It might not respond fast enough in bad weather. And if you don’t know whether it worked (or should have), it can complicate how fault is determined.
Does Automatic Emergency Braking Affect Who’s at Fault in a Car Accident?
South Carolina’s Fault Rules Still Apply
In South Carolina, fault matters, and it’s shared when both parties contributed. That’s called modified comparative negligence. If you’re found to be more than 50% at fault, you lose your right to recover damages.
So when AEB is involved, it might raise questions:
Should your car have prevented the crash?
Or
Was the other driver still responsible, regardless of the tech?
When Technology Gets Pulled Into Blame
It’s not just about two drivers anymore. Sometimes fault gets split between the person, the car, and even the mechanic. For example, if your AEB didn’t activate because a sensor was misaligned during a windshield replacement, liability could shift to the repair shop.
Other times, the system may not have been expected to work in that specific scenario, and that needs to be investigated.
Here’s What Can Happen When AEB Gets It Wrong
A Columbia Driver’s Unexpected Rear-End Collision
Let’s say someone in Columbia is driving a new SUV equipped with auto emergency braking. Traffic slows ahead, and the driver glances away from the road for a second, expecting the car to react if something sudden happens. It doesn’t, and they rear-end the car in front .The other driver files a claim. The insurance company says the SUV driver was at fault for “not paying attention.”
But here’s the twist: a later inspection reveals the AEB sensors weren’t working correctly after a recent repair. The SUV owner didn’t even know.
So who pays?
In that case, fault didn’t land squarely on the driver. It was shared with the repair shop, and the claim got more complicated than expected.
How Insurance Companies Might Use Automatic Emergency Braking Against You
“You Were Relying on Tech Too Much”
One common tactic? Saying the driver depended too heavily on the auto emergency braking. Insurers may argue that relying on automatic braking shows a lack of caution.
But here’s the truth: the law doesn’t say you’re responsible for double-checking every feature your car comes with. Drivers expect safety systems to help, not fail them.
“Your Car Should’ve Stopped”
If your car has AEB, some insurers might argue the crash should’ve been avoided. But South Carolina insurance laws don’t automatically assign blame just because technology was involved. The South Carolina Department of Insurance explains how fault is still based on the full picture, including driver behavior, road conditions, and vehicle function.
It’s easy to point fingers after the fact. What really matters is whether the system was expected to kick in, and whether it actually did.
What If the Other Driver Had AEB and Still Hit You?
Can That Work in Your Favor?
Yes. If the at-fault driver had a newer car with automatic emergency braking but still caused the crash, that might strengthen your case. It shows the system either failed or was ignored.
But here’s the problem: this information isn’t always easy to get unless someone knows how to ask for it.
Getting the Right Evidence
Crash reports don’t list whether auto emergency braking systems were involved. You’ll need vehicle data, repair history, or even software logs, things you won’t get from a basic insurance exchange at the scene. That’s where a Columbia auto accident attorney becomes key.
What This Means for Your Car Accident Claim in South Carolina
Automatic emergency braking doesn’t automatically protect your rights. And insurers don’t just hand over system data; they may not even know it exists unless you push for it. Having the right people investigate the car’s features and performance could make a big difference in how your claim turns out.
You Still Have a Case, Even If AEB Was Involved
Just because your car had AEB doesn’t mean you’re to blame. South Carolina law still looks at what happened and why. If the system failed or wasn’t expected to respond, that’s not your fault. What matters is getting the full picture, not letting assumptions drive the outcome.
Steps You Can Take Right Now
Start Documenting What You Know
Right after the crash, make sure you collect:
- Photos of all damage (yours and theirs)
- Vehicle info including year, make, and safety features
- A detailed timeline of what you remember
Even small notes, like “my brakes didn’t feel like they kicked in,” can help later.
Get a Professional Inspection of Your Vehicle
Some newer vehicles store crash data and braking events. Others require dealership diagnostics. Either way, it’s worth asking if the automatic emergency braking system was working correctly and, if not, why.
