Black Boxes: The Secrets Your Vehicle Keeps

Published on: July 30, 2019

By Brian Butler

Many do not realize modern vehicles are always ready to record critical driving information. As with airplanes, most passenger vehicles are now equipped with Event Data Recorders (EDR), or "Black Boxes." This information may be critical after an accident to show what happened, and who was at fault.

EDRs may record pre-event data for five seconds before and one second after an accident, possibly including vehicle speed, engine speed, percent throttle, change in velocity, and whether the brakes were applied. The make and model of the vehicle will determine what data is available. If you want this data, you must act quickly because it will be “overwritten” at some point if the vehicle continues in use.

It is also important to retain a competent expert to download the data. In Laborde v. Shelter Mutual Insurance Co., 82 So. 3rd 1237 (La. 3/9/2011), the trial court excluded the printout of data downloaded from a Black Box because of the boxes "chain of custody" and the method the information downloaded. It is important that your legal team knows how to obtain and preserve this evidence.

Data from Black Boxes can be useful in many ways. In some cases, it may help to prove that the accident involved a low impact or to show that no brakes were applied. In other cases, it may harm your position, but the data is almost always relevant. There are costs in downloading and interpreting the data. But in the right case, the secrets kept in the Black Box may be the only way to reveal the truth.

Preparing for a Storm

Fortunately, the 2024 hurricane season has been relatively calm. We previously blogged about steps that can be taken after your property is damaged by a hurricane or other natural disaster. (Click here to access our prior blog). With a Tropical Storm, and potential Hurricane, threatening our coast, here are some steps to consider taking to prepare before a storm arrives in the event you must make a property insurance claim for damages after the storm:

  • DOCUMENT, DOCUMENT, DOCUMENT – The best way to prove the condition of your property before damage is caused is to document it. Take pictures and videos of the interior and exterior of your home or business. Create an inventory of your contents. Narrate the video to provide better descriptions. If your property is damaged, this documentation will be used to verify its condition and make it easier for your insurer to adjust and pay your claim.
  • INSPECT YOUR PROPERTY – As you are making your preparations, you may consider taking a walk around your property to notice any prior damage to your property. Identify any issues that could affect a potential insurance claim.
  • KNOW YOUR INSURANCE COVERAGES – Make sure you are aware of the coverages that your insurance policy provides. The Declarations Page to your policy should provide much of this information – the coverage limits, types of coverage provided, deductible, etc. While your insurance agent likely maintains this for you, it is good practice to maintain and know this information, which lets you know what will or will not be covered.
  • MITIGATE YOUR DAMAGES – You can take steps to prevent damage to your property during the storm. You can pick up items around the property that could become airborne and take whatever precautions you can to prevent damage to your property, particularly the exterior. If your property is damaged, you can make temporary repairs to prevent further damage until your insurance company can get to you (like placing a tarp on the roof).

Louisiana Court Limits Use of Biomechanical Expert Testimony

The use of biomechanical expert testimony in Louisiana courts has evolved over the last few years. A recent decision from the Louisiana Fifth Circuit Court of Appeal provides an example of the changing standards for the admissibility of biomechanical expert testimony and its relation to medical causation.

In Pollard v. 21st Century Centennial Ins. Co., 21-65 (La. App. 5 Cir. 12/23/21), 334 So. 3d 1013, writ denied, 2022-00163 (La. 4/20/22), the defendants argued that the underlying accident involved a minor rear-end impact not likely to cause injury. The defendants hired a biomechanical expert who was also a medical doctor. The expert performed an “impact severity analysis” to determine the force of impact in the collision.

The expert concluded that the accident involved a minimum damage collision; he relied upon the “force reflection method” and test data at his crash test facility to determine how fast the rear-ending vehicle would have traveled to cause the damage present on the plaintiff’s vehicle. Based upon his findings, the expert opined that the plaintiff was not seriously injured in the collision. He went further to testify that specific injuries could not have been caused by the forces involved.

The Fifth Circuit noted the same expert was previously excluded in a case that went to the Louisiana Supreme Court in Blair v. Coney, 2019-00795 (La. 4/3/20), reh'g denied, 2019-00795 (La. 7/9/20), 298 So. 3d 168, where the Court found the expert’s testimony to be based upon insufficient facts or data. In Blair, the Supreme Court found the expert’s testimony should be excluded because he did not (1) inspect either vehicle involved in the collision; (2) speak with the damage appraisers; (3) know the plaintiff’s body position at the time of the accident; (4) inspect plaintiff’s vehicle for variance from the test-vehicle or (5) interview the plaintiff. Thus, his testimony failed to meet the requirements of C.E. art. 702(A)(2).

Citing the Blair decision, the Louisiana Fifth Circuit in Pollard concluded that the expert “relied on the same [improper] methodology in reaching his conclusions.” Therefore, the appellate court found the trial court erred in denying a motion in limine to exclude the expert’s testimony. Although the expert cited to peer-reviewed literature to support his conclusions, the evidence revealed that “most of the research and articles” he cited were either written by him or one of his employees.

Effective January 1, 2021, Louisiana amended La. R.S. 32.295.1, which now allows the admission of a plaintiff’s failure to wear a seat belt as a factor to be considered in comparative fault. Defendants will seek to use biomechanical experts to prove that the failure to use a seatbelt substantially caused or contributed to the damages.

Biomechanical testimony may be allowed. However, as shown in Pollard, biomechanical opinions which lack sufficient inquiry to match the analysis to the real-world impact will be treated with skepticism. Taking Blair and Pollard together, the courts appear to resist expert biomechanical opinions which seek to definitively resolve medical causation which often involves subjective elements and credibility determinations reserved for the trier of fact.

It is certain that defendants will continue to advance the “low impact” argument because force-of-impact testimony is a relevant factor in determining causation or extent of injuries. See, e.g., Merrells v. State Farm Mutual Auto, Ins. Co., 33-404 (La. App. 2 Cir. 6/21/00), 764 So. 2d 1182. What is less than certain is the role of the biomechanical expert. Following the Fifth Circuit’s decision in Pollard, the Louisiana Supreme court denied the defendant’s writ application 4 to 3, with all three dissenters advising they would have granted the writ. Issues surrounding the use and scope of testimony from biomechanical experts appear far from settled.

Medical Malpractice: Can failure to communicate test results be medical malpractice?

The Louisiana Fourth Circuit Court of Appeal recently considered a medical malpractice case with an unusual set of facts. Rather than the standard medical malpractice case, where a patient argues that he was misdiagnosed and/or claims that the doctor made a mistake when administering medical treatment, in Dufreche v. Jeffery Wayne Coco, MD and Internal Medicine Specialists, Inc., 2020-CA-0030 (La. App. 4th Cir.), the patient alleged that his doctor committed malpractice by failing to communicate test results.

In Dufreche, the patient showed signs of an HIV infection. He was tested twice before being treated by the infectious disease specialist. Both tests were negative. During his examination, the infectious disease doctor thought it was unlikely that the patient had HIV, but tested him anyway at the patient’s insistence. According to the patient, he was notified by the doctor that he would be provided the results upon receipt.

Unfortunately, the test results showed that the patient was HIV positive; however, he was not contacted. Fifteen months passed, during which the patient was unaware that he was HIV positive. Because he was not contacted, he assumed he was negative. When testing by another physician showed he was positive, the patient/plaintiff filed suit to recover damages allegedly suffered through a delay in treatment and psychological shock, including a claim for “emotional distress.”

To recover, the patient was required to establish: 1) the standard of care; 2) breach of that standard of care; and 3) that the breach caused his emotional distress. At trial, the doctor testified that he required his patients to follow up in person to receive test results, and expected the patients to contact his office to schedule an appointment. The court found that expecting a patient to follow up in person to receive sensitive test results was not a breach of the standard of care. However, the evidence established that the patient was not instructed that he must schedule an in-person appointment to obtain his test results.

The Dufreche court agreed with the lower court in finding that a failure to notify the patient of the doctor’s policy was a breach of the standard of care. Further, the court found that the infectious disease specialist, who admitted to a duty to the public to protect them from HIV, had also breached his duty for failing to notify an HIV positive patient of his diagnosis for over fifteen months. The doctor’s failure to communicate the results caused the patient’s emotional distress – resulting in an award of $45,000 in damages.
