Using Black Box Data in Indiana Truck Accident Cases

Article by Tuley Law staff

As experienced Indiana truck accident attorneys, we know that determining fault is crucial for securing justice and appropriate compensation in a semi-crash case. One of the most convincing sources of evidence in modern truck accident litigation is the data recorded by a truck’s “black box.”

Let’s explore the role of black box data in truck accidents and how it can be used to prove liability.

What Is a Black Box in a Truck?

A commercial truck’s black box is an electronic device that continuously records operational data about the vehicle, similar to the black boxes used in airplanes. Officially known as on-board event data recorders (EDRs), these devices are typically part of the truck’s onboard diagnostics system, which monitors the engine, braking system, and other vital components.

Truck accident black box evidence can include a wide variety of data, such as:

• Speed of the truck at any given time, particularly right before the accident
• Braking behavior, such as when and how hard the brakes were applied, indicating whether the driver attempted to stop or slow down before the crash
• Amount of acceleration the driver applied during the moments leading up to the incident
• Engine RPM, which may indicate whether the engine was operating normally or was showing signs of malfunction
• Inconsistent or questionable driver actions, such as engaging cruise control, manual operation of the truck, opening doors, using hands-on communication methods, etc.
• Time stamps, which show exact times for key events, such as acceleration, braking, or engine failure

Some advanced black boxes also record information about whether safety features like lane-keeping assist, automatic braking, or collision avoidance systems were active or engaged during the crash. You won’t know what’s on the electronic logging device from a truck accident until our attorneys track down this often critical information.

Why Is Black Box Data Crucial in Truck Accident Cases?

There’s no limit to how black box data helps truck accident claims for injured parties. As a precise, linear account of actions and vehicle conditions, it paints an unassailable picture of the events leading up to the crash.

Black box data can be an invaluable resource in proving fault in truck accident cases for several reasons:

• Impartiality. Black box data provides objective, hard evidence that is difficult to dispute. While eyewitness accounts and driver testimony can be influenced by memory, bias, or human error, the data from the black box is an impartial record of the truck’s operation.
• Behavior patterns. If the black box shows that the driver did not attempt to slow down or stop—or that the acceleration was unusually rapid before the crash—this data can help establish whether the driver was paying attention or acting recklessly.
• Mechanical failures. The black box can reveal if mechanical issues, such as brake failure or engine malfunction, contributed to the accident. If a malfunction is found, the truck owner or maintenance provider may be held liable for failure to maintain the vehicle properly.
• Compliance with regulations. Commercial carriers must follow state and federal regulations, including rest period requirements, speed limits, and weight restrictions. The black box data can prove whether the driver broke these rules. Violations could indicate driver fatigue, overloading, or other unsafe behaviors contributing to the accident.

How Can Truck Wreck Lawyers Get Black Box Data?

Obtaining black box data can be challenging. Trucking companies and insurance providers may not voluntarily release this data, especially if it could be used to show liability. The data may also be overwritten after a set period of time, making early action vital.

Here’s how our attorneys work to obtain this valuable information:

• Discovery. In many cases, lawyers can request black box data through the legal discovery process. This involves formally requesting the data from the trucking company or the insurance company as part of pre-trial litigation.
• Subpoenas. If the trucking company is unwilling to voluntarily provide the black box data, our lawyers can issue a subpoena, legally compelling the company to turn it over.
• Accident reconstruction and expert witnesses. In some cases, lawyers may hire an expert in accident reconstruction or a forensic engineer specializing in retrieving and analyzing black box data. These professionals have the knowledge and tools to access the black box, interpret the data, and present it in a way that a judge or jury can understand.
• Third-party investigators. If a trucking company is uncooperative or the data is time-sensitive, a third-party investigator may be hired to extract the black box data independently. This may involve working with data retrieval specialists who can access and preserve the data before it is lost or erased.
• Fleet management systems. Some modern fleets employ telematics systems that track data on real-time truck operations. In such cases, the data may be stored in a cloud system or on the fleet’s servers, and a lawyer can obtain it directly from these systems.

What Other Evidence Do I Need in a Truck Wreck Case?

While we work to obtain black box information in truck crashes, it’s just one part of the puzzle. Truck accidents are complex events usually involving multiple factors, such as company negligence, trailer maintenance, driver inattention, poor road conditions, and other external elements.

A successful truck accident lawsuit requires multiple types of evidence, strong negotiation skills, and a willingness to go to trial to seek compensation for your losses. Contact Tuley Law Office today for a free consultation on your case.
