How “Black Box” Data Can Help Win Michigan Car Accident Lawsuits

Large commercial trucks are required to keep recording devices that are commonly known as block boxes. After a collision involving a semi-truck, showing how “Black Box” data can help win Michigan car accident lawsuits can be crucial for anyone seeking compensation for injuries and vehicle damage. Read on to learn about these complex devices and how an attorney can help you access data that could prove crucial for your injury claim.

What Are Black Boxes?

There are more than 221,100 commercial truck drivers in Michigan, and many of their vehicles are equipped with electronic data records that are commonly referred to as “black boxes.” These devices capture key information about a vehicle’s operation in the comments before and during a crash. In commercial trucks, this data is typically stored in an event data recorder or is part of a broader electronic logging system.

Black boxes can record details such as speed, braking activity, throttle position, seatbelt usage, and engine performance. Some systems also track driver hours and vehicle location. This information becomes especially important after a collision because the data can help reconstruct how the crash occurred.

In legal claims, black box data can provide objective evidence that supports or challenges statements made by drivers and witnesses. The data may show whether a driver attempted to brake and how fast they were traveling in the moments leading up to the collision. When paired with other data, such as video footage from a dashcam, a black box can provide crucial insight that is used to establish fault following a crash involving a commercial truck.

Who Has Access to Black Box Data After an Accident?

After a car collision, trucking groups often take steps to protect their interests. If you do not have legal representation, you are unlikely to be able to access critical evidence from a black box. Since those devices belong to the driver or the company that owns the truck, you would need the permission of the owner to secure crucial data from those devices.

This is where legal representation can play a critical role in helping you pursue the compensation that you are owed. An attorney can go to the 52nd District Court or another local court in Michigan to ask for a subpoena that allows for access to a black box. When the courts become involved in the process, the trucking company can no longer refuse to provide you with data that can be used to build a strong injury claim.

A subpoena is a legal order that requires a party to preserve and produce specific evidence. Failure to comply with these orders can result in penalties, including fines or even court-imposed consequences.

Why You Should Hire a Car Accident Lawyer from Wigod & Falzon

If you were injured in a collision involving a commercial vehicle, your top priority should be to hire an experienced car accident lawyer who understands California’s car accident laws and how to explain the black box’s meaning in clear terms. A Michigan car accident attorney can work with the at-fault party’s insurance company or subpoena the other company to gain access to critical black box data.

Excessive speed is tied to 11.7% of fatal crashes in the state, and black box data could show that the truck driver was speeding at the time of the collision. Distracted driving caused 315,167 injuries across the country, and a lawyer’s decisive actions can help gather the evidence that is needed to show that an injury resulted from the truck driver’s failure to pay attention to the road.

FAQs

How Can Black Box Data Strengthen a Car Accident Claim in Michigan?

Black box data can provide objective information about a vehicle’s speed, braking, and driver actions before a crash. This data can help reconstruct how the accident occurred and which party or parties may be at fault for causing a collision. In Michigan, these devices are considered strong and objective forms of evidence. Their use alongside police reports, witness statements, and analysis by consultants can build a strong claim.

What Should You Avoid Telling Your Insurance Company After a Crash?

After a crash, you should avoid admitting fault, speculating about what happened, or downplaying your injuries when speaking with your insurance company. Statements can be used to limit or deny your claim, which is why you should just stick to the facts and avoid recorded statements without first speaking to an injury lawyer. Guessing at what caused the collision could lead to setbacks for your injury claim.

Do Insurance Companies Retrieve Black Box Data After an Accident?

After an accident in Michigan, insurance companies have an interest in establishing fault. Their investigation may include an analysis of the truck’s black box. Even with access to raw data, their interpretations may not always be correct. Having legal representation can play a key role in protecting your interests. Insurance companies have their own priorities that may not align with yours.

Can Black Box Data Help Prove Fault in a Collision?

Yes. Black box data can help prove fault by showing key details such as speed, braking patterns, and throttle use before an impact. This information can confirm or challenge driver statements and support accident reconstruction. When combined with other evidence, it can provide a clearer picture of responsibility and strengthen arguments in a collision claim.
