When people hear “black box,” they think of airplanes and disasters. But nearly every modern car on Michigan roads has its own version—a vehicle event data recorder (EDR). And while it’s often used after a crash, its power goes far beyond basic accident reconstruction.

That little device could be the one thing that stands between your word and a cover-up.

At Marko Law, we’ve used vehicle black box data to:

• Disprove lies on police reports
• Expose employer negligence
• Support wrongful death lawsuits
• And hold public and private entities accountable**

This technology doesn’t just log speed or seatbelts. It tells the story of what really happened—how fast you were going, when the brakes were hit, if the airbags deployed, even whether someone was wearing a seatbelt. And in the right hands, that story can be the difference between injustice and a multi-million-dollar verdict.

But here’s the catch: most people don’t even know the data exists—let alone how to protect or use it.

If you’ve been in a crash—or if someone’s trying to cover their tracks—your car’s black box could be your strongest ally. And at Marko Law, we know exactly how to access it, preserve it, and make it matter in court.

What Is a Vehicle “Black Box”?

When we talk about a vehicle’s “black box,” we’re referring to what’s technically known as an Event Data Recorder, or EDR. It’s a built-in device that collects crucial data from your vehicle, especially in the moments before, during, and after a crash.

Though it doesn’t capture audio or video, the EDR silently tracks your car’s movements and mechanical actions—information that can become vital in a legal investigation.

What Does the EDR Record?

An EDR can provide a minute-by-minute breakdown of what happened during a collision. The data points typically include:

• Vehicle speed at the time of the crash and in the moments leading up to it
• Brake use, showing whether and when the driver attempted to slow down or stop
• Steering angle, which can indicate if evasive maneuvers were attempted
• Seat belt status, showing whether occupants were buckled
• Impact force, helping to assess the severity of the crash
• Airbag deployment, including the timing and which airbags were triggered

Standard Equipment Since 2013

While some vehicles were equipped earlier, federal regulations have made EDRs standard in most passenger vehicles manufactured after 2013. That means if you’re driving a relatively modern car, your vehicle is likely recording every second leading up to a crash.

Triggered Before and During an Accident

EDRs are usually activated by a significant event, like sudden deceleration or collision impact. In many cases, they start recording data just seconds before a crash occurs. This window—often as small as 5 to 20 seconds—can make all the difference when trying to prove what really happened.

Why Your EDR Data Matters in Michigan Injury & Civil Rights Cases

Proving or Disproving Fault in Crashes

In Michigan, fault still matters. Even under the no-fault insurance system, establishing who caused a serious crash can determine who pays for pain and suffering, excess medical bills, or long-term care. EDR data helps prove:

• Whether the driver was speeding
• If brakes were applied
• Whether evasive action was attempted
• The true severity of the impact

Discrediting False Statements and Cover-Ups

EDR data doesn’t lie. It can be used to directly challenge:

• Inaccurate police reports
• False statements made by employers or company drivers
• Attempts by other drivers to shift blame

What the Data May Reveal

The EDR’s value goes beyond the basics. It can also show:

• Reckless behavior, like high-speed driving or failure to brake
• Lack of evasive action, which may prove negligence or impairment
• Possible tampering or mechanical failures that would otherwise go unnoticed

Relevant in More Than Just Crashes

EDR data plays a major role in a range of Michigan legal cases, including:

• Car, truck, and motorcycle accidents where liability is in question
• Police chases or excessive force cases involving civilian injuries or vehicle-related deaths
• Employer vehicle misuse, especially when companies try to cover up unsafe practices or negligent hiring
• Wrongful death investigations, where surviving family members need answers the responsible party won’t give

Legal Power of EDR Data in Court

Admissible in Michigan Courts

EDR data is considered admissible expert evidence in Michigan courts. That means it can be used to support or challenge claims during a trial—often introduced through accident reconstruction experts who interpret the data and explain it clearly to a jury.

Backed by Reconstruction Experts

The data doesn’t stand alone. Marko Law works closely with top-tier accident reconstruction professionals who analyze the black box data alongside physical evidence—like skid marks, vehicle damage, and surveillance footage.

Can Contradict Sworn Testimony

One of the most powerful uses of EDR data is its ability to discredit false narratives.

We’ve seen it contradict:

• Police reports claiming a suspect was fleeing
• Employer statements saying their driver followed all safety protocols
• Defendants who swore under oath they weren’t speeding or driving recklessly

Protected Under Spoliation Rules

In Michigan, EDR data must be preserved once a party knows (or should know) it could be evidence in a legal claim. Destroying, deleting, or tampering with that data—known as spoliation—can result in serious legal consequences, including sanctions or default judgments.

Who Owns the Data—and How Can You Get It?

One of the biggest misconceptions about vehicle “black box” data is that it belongs to the police, insurance companies, or even the manufacturer. That’s not true. Under Michigan law, specifically MCL 257.715, the data recorded by your vehicle’s Event Data Recorder (EDR) belongs to the vehicle owner.

But just because you legally own it doesn’t mean it’s always protected—or easy to access.

Your Data, Their Hands

Despite what the law says, police departments, insurance adjusters, and even auto manufacturers often pull or overwrite EDR data without your clear consent. This can happen right after a crash, when your car is towed and you’re still in the hospital or dealing with shock. Most people don’t even realize that the data’s been accessed—let alone how it might be used against them later.

If you don’t act fast, your data can disappear. And once it's gone, you lose a powerful tool that could prove your case—or destroy someone else's lies.

Why Speed—and Legal Support—Matters

Accessing EDR data is not as simple as plugging in a USB drive. It often requires:

• Specialized hardware and software
• A legal right to retrieve the data (especially if the car isn’t in your possession)
• An understanding of how to interpret the data in context

That’s why your best move is to hire a legal team immediately—one that knows how to:

• Send preservation letters to prevent data loss
• Subpoena the EDR if the vehicle is owned by someone else
• Work with forensic experts to analyze and explain the findings
• Use the evidence in court to prove fault, discredit false claims, or establish a timeline

We understand the technical side—and more importantly, we know how to make that data matter in a courtroom.

Your Car's Black Box Could Be the Key to Justice

The truth doesn’t always come from witnesses. It doesn’t always come from police reports or insurance statements. Sometimes, the most reliable voice in the room is your car’s black box—and in the hands of the right legal team, it can speak volumes.

Whether you’ve been in a crash, lost someone you love in a wrongful death incident, or are facing false accusations tied to a vehicle, the EDR inside your car might be the evidence that proves what really happened. Speed, braking, seat belt use, impact force—it’s all there. And once it’s gone, it’s gone for good.

At Marko Law, we’ve spent years uncovering the truth for people who were lied to, ignored, or blamed. We don’t just file claims—we investigate, preserve evidence, and expose cover-ups. Because that little black box isn’t just a piece of tech. It’s a truth-teller. And it could be your biggest weapon.
