They were the two researchers who exposed the cyber-security holes in the FCA/Chrysler connectivity system that left their vehicles vulnerable to cyber-attacks. Miller and Valasek famously conducted a test whereby they hacked into a Jeep’s system and took command of many of the vehicle’s controls – remotely – while it was traveling down a freeway. (The full story is definitely worth reading – click here)  In further tests, by hacking remotely they could disable or slam on a victim’s brakes,…..

Did you know that every 2 days, on average, work-related ladder falls result in 1 death and more than 180 injuries, resulting in $24 billion a year in related costs, including work loss and expenses for medical, legal, liability, and pain/suffering, according to the National Institute for Occupational Safety and Health (NIOSH). Dr. Angela DiDomenico, Senior Biomechanist at ARCCA, was interviewed recently for an article on Ladder Safety that appeared in the March 13, 2017 issue of the BLR (Business and Legal Resources) OSHA Compliance Advisor Newsletter, where she opined on the role of human factors in ladder falls. Angela…..

When you have a case or claim involving bodily injury it is important to investigate causation, which is essential when determining whether the person’s injury was work-related or from Sunday softball……

The Seat Belt Defense is a comparative negligence argument.  At least fifteen states have adopted some form of the Seat Belt Defense law. The seat belt in any automobile is a restraining device that controls the motion of a seated occupant in a crash by coupling the occupant’s body to the vehicle through the strong bones of the body.  This allows the occupant to be brought to a stop in the safest possible manner. The dynamic motion of an occupant during a crash, known as kinematics, follows the fundamental Laws of Physics. The Seat Belt Defense is a form of…..

A high school student was working at a boat sales and service shop and was asked to adjust the idle speed on a customer’s boat. The boat had a 120 horsepower engine. He removed the engine cover to perform the service. A flywheel and ring gear were located on the top of the engine with no cover or guard. The service required the engine to be running to adjust the idle speed, and the mechanic was attempting to adjust the throttle stop screw when his right arm contacted the unguarded rotating flywheel causing significant injuries to his arm. When investigating…..

Enhanced damages and staged collisions are often difficult to identify. When hundreds of claims pass through your desk, there is no “red flag” that raises when a veteran body shop or claimant subtly enhances the damages claimed. How do you know if the collision was staged? Why didn’t the airbags deploy? Why does one vehicle have $8K in damages, while the other vehicle only needed a simple bumper refinish? Learn the answers to those questions when Shawn Harrington, Director of Accident Reconstruction at ARCCA, presents on this topic: April 12, 2017 11am PT; 12:00 MT; 1:00pm CT; and 2pm ET This webinar is…..

Autonomous racing? Robot cars racing each other, humans programming them, and no risk to humans involved in 199 MPH collisions? Sounds like a video game, but it’s real. And it looks awesome. Roborace will pit self-driving race cars against each other, and the design in this link is a 2,149 pound beauty (when you don’t have to design for a human occupant, the designs are insane). It is an electric Formula E circuit, so four 300-kW electric motors power each wheel. We will totally watch this. If the words “tort law”, “computer tortfeasors”, and “negligence standards” get you excited (particularly…..

Slips, trips and falls occur on a regular basis and for a variety of reasons.  Angela DiDomenico, PhD, a Senior Biomechanist and Certified Professional Ergonomist at ARCCA, will discuss the causative factors involved in slip, trip and fall events via a webinar to be held Tuesday, March 28, 2017, at 1 pm EST. The NASP (National Association of Subrogation Professionals) will be hosting the webinar. Dr. DiDomenico’s presentation will show how biomechanical injury analyses are used to address both damages (i.e. whether the claimed injuries occurred in the described event) and liability (i.e. whether a purported defect was proximate to…..

One of the most interesting innovations that will shake out of the autonomous vehicle revolution will be the legislation of this new segment. As of now, legislation is left up to the states, which has created different playgrounds for autonomous vehicles and different rules for each playground. Today we’ll take a look at Michigan’s new rules for autonomous vehicles. Michigan signed groundbreaking legislation into law that allows more freedom to autonomous car manufacturers than ever before. The group of bills, known formally as Senate Bills 995-998 or collectively as the SAVE Act, allows manufacturers to (1) put automated vehicles on highways…..

Every year, the auto industry attempts to innovate new ways to make the driving experience “smarter” to compete with the rapidly changing smartphone and device segment. The in-dash infotainment center (the words “information” and “entertainment” combined) is their best chance to grab your attention (and your data) when you are driving your vehicle. Some infotainment features include hands-free voice technology, apps, integrated GPS, and 4G-connectivity capabilities. These are just some of the functions we as consumers are aware of. But what about the other capabilities our infotainment systems have that we generally take for granted or do not even know…..

We are fascinated by the issue of liability when autonomous vehicles are involved in accidents. Let’s set individual state-by-state rules for autonomous vehicles aside for a moment (we will cover that beast in the future). The issue of who is to blame when the inevitable accident occurs is sticky, at best. Automotive News did a piece a couple of years ago that posed three different scenarios to a law professor, and it is an interesting read. It is my belief that liability disputes against other parties who own or insure the vehicles will take a backseat to large product liability…..

As reported in the news, a popular toy (“disruptive technology device”) has had issues with fires. There are many news videos of these devices spontaneously bursting into flames, and they have been banned from being transported on commercial airline flights. Unfortunately, with the increased use of computer power and technology in product design and manufacturing, the time to production for a new product has significantly decreased. Traditionally, this process would take into account the time needed to design, test, validate and re-design it if necessary, and then it would be sent to manufacturing for mass production. This process tends to…..

Welcome to our new CrashAxe Newsletter – your weekly source for the latest information in the world of autonomous vehicles. Here we go… As part of a ten-day pilot program that began early last week in Las Vegas, a new driverless shuttle has begun test driving the city streets. This new shuttle hopes to be bussing people around in the near future as it is fully electric and requires no driver. The developing company, Navya, has dubbed its latest success Arma. The company’s spokesman Martin Higgins called it “100 percent autonomous on a programmed route.” Later this year, the city hopes to have several…..

With the days being shorter in the winter season, bicycle riding at night, dawn, or dusk greatly increases your risk of an accident as compared to riding during daylight hours. This is in part due to bicyclists being difficult for motorists to see. Consequently, bicyclists should take extra precautions to make themselves more visible and, specifically, more identifiable as a person/bicyclist. By law, a bicycle operating at night is required to have a white front light and a red rear flashing light or a red reflector. Bicyclists can use two front lights, one operating in a steady mode and the…..

When materials break, or fracture, they do so in one of two modes – ductile or brittle. For ductile fracture, picture chewing gum. After the gum has been chewed some, it can be stretched quite a bit before breaking and the cross section gets very thin. For brittle fracture, picture window glass. When it gets stressed, it shatters without stretching at all, and the thickness doesn’t change much either. Most materials exhibit ductile or brittle behavior under different conditions. For instance, consider the chewing gum, but imagine it has been frozen in liquid nitrogen. In that cold state, it shatters…..

The U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS) reported that U.S. airlines and foreign airlines serving the United States carried an all-time high of 895.5 million system-wide (domestic and international) scheduled service passengers in 2015. With all of that volume, there will unfortunately be airplane crashes, but the number of non-flight related airport incidents is more likely to increase as well. In addition to investigating crashes, ARCCA’s engineers also evaluate all non-flight related airport incidents, including trip and falls, slip and falls, escalator incidents, tarmac incidents, baggage handling, crew member incidents, jet bridge incidents, motor vehicle incidents, and…..

Water losses can be overwhelming for property owners and residents, and the cost of repairs can be very high. Many times dezincification of plumbing components is indicated as the cause of the loss. This leaves non-metallurgists wondering “what is dezincification?” Brass is an alloy, a mixture of copper and zinc with some other elements added. Copper usually makes up the majority of the elements in brass, and zinc is added to the copper. The amount of zinc added can vary from 5% to 45%, depending on the alloy. Note that pure zinc is bluish-white in color, while copper is red……

On Nov. 23, 2016, CBS News provided an update in its series regarding the urgent need for improved regulations concerning seat back strength in automobiles. It reported that several US Senators are sending a letter to NHTSA demanding that the agency take immediate action to remedy this significant seating system requirement deficiency. As reported by CBS, “every day on average, three children are killed and 470 injured in accidents – 11% of those child victims are in the rear seats where the government recommends children sit.” When seat backs fail in a rear-end collision, the driver and/or front seat passenger can be forced rearward, striking a child…..

Each of us has experienced fatigue in our lives, a time when we were extremely tired, typically due to long or intense mental or physical exertion. It turns out that materials experience fatigue too, although not the mental kind. In the field of Materials Science Engineering or Metallurgy, the term “fatigue” has a very specific meaning. In the engineering sense, fatigue is a progressive failure, most often caused by the initiation and growth of a single dominant crack that occurs due to repeated, or cyclic, loading. Initially, when these types of failures were observed in the early 1800s, it was thought…..

About 27 people are killed in elevator accidents each year, according to the U.S. Bureau of Labor Statistics and the CPSC. Injuries from elevators affect about 10,200 people per year, with the majority of these accidents being related to elevator door malfunction, carriage misalignment with floors, and passenger safety vulnerabilities. The U.S. Labor Department’s Census of Fatal Occupational Injuries reports that half of the annual elevator-related fatalities occur in repair or maintenance workers who service elevators, or people who use elevators as part of their employment, such as in an office building. In the occupational-related elevator deaths category, 53 percent…..

The National Fire Protection Association (NFPA) residential sprinkler initiative was launched in 2009 in an attempt to get sprinklers installed for new residential construction. The idea was relatively simple. Properly designed, working, maintained, and inspected sprinkler systems have been shown to halt a fire, slow fire spread, reduce levels of products of combustion, give people more time to evacuate, and give fire fighters more time to respond to a fire. The NFPA’s initiative was successful in getting adopted by the International Codes Council’s IRC (International Residential Code). However, to date, only California, Maryland and the District of Columbia have accepted the…..

Biomechanical engineers apply the laws of physics and the tools and approaches of mechanical engineering to the joints and tissues of the human body. They investigate the response of the human body to the application of mechanical forces to determine the potential for injury. In an incident where injuries are claimed, it is not their role to proffer opinions regarding the presence of any diagnosed injuries, but rather to evaluate causation and determine whether a causal relationship exists between the claimed injuries and a specific incident. Medical doctors are trained to diagnose injuries, but often times they lack the expertise…..

Accident reconstructionists are often asked to determine whether the damage to a vehicle’s bumper is consistent with the reported accident or crash. While performing an inspection and analysis of the damage in question, the reconstructionist will generally be considering the following: The forces transferred to and from the bumper must be equal and opposite. The principal direction of forces between the bumper and the other vehicle/objects will define the line of action and the resulting bumper deformation. The deformation of the bumper will at first be elastic. Elastic deformation means that upon removal of force, the bumper will return to…..

The problem of unrestrained cargo in vehicles is an issue that has been known about for years but has not been sufficiently addressed by the federal government and the auto industry in the US. If cargo is not adequately restrained, it can shift during vehicle maneuvering, braking and, most dangerously, in a crash. While minor shifting can occur without any problems, there have been many instances where unrestrained cargo has been responsible for injuries to vehicle occupants. As an example, ARCCA was involved in a case where a child returning home with his parents after a hockey game was paralyzed…..

When an accident reconstruction expert is investigating how an accident happened, a site inspection can provide vital information. This was shown to be true in a case where early one morning in the darkness before dawn, a large sedan was traveling southbound on an unlit 4-lane divided rural road with a small grass median between the opposing lanes. The sedan collided with the side of a low-boy construction trailer that had stopped while making a left turn across the sedan’s lane. A construction gate on a driveway had been closed and the northbound tractor/trailer had to stop, as he could…..

The current design of bicycle helmets entails an EPS (expanded polystyrene) liner with fixed a hard plastic outer shell cover. The EPS liner is the primary protective design feature that crushes and absorbs the impact energy. Ultimately, the EPS liner reduces the energy transmitted to the skull and brain, thereby reducing the risk of injury. The hard shell feature helps prevent the helmet from snagging on the pavement and inducing neck injuries in addition to distributing the impact force over a wider area. Head and specifically brain injuries are not solely due to a direct linear type of impact. Brain…..

Some people have bad days that just get worse. As an accident reconstructionist, I’ve experienced some cases where the driver just could not catch a break. John was driving his pickup in a Pennsylvania rainstorm on a 2-lane state highway when an oncoming sedan lost control and spun into his lane. The impact on the front and side of his truck forced him onto the narrow shoulder to his right and into contact with the guiderail. A bad day for anyone, but it didn’t end there. His pickup struck the guiderail, rolled over it into the ditch beside the road…..

As accident reconstructionists, we strive to explain the circumstances leading up to a collision and the vehicle dynamics of the collision. In doing so, we’ve uncovered insurance fraud in some of our cases where the investigation has actually shown that the collision could not have taken place as claimed. One such case was a claim that a parked car had been heavily side-swiped by another passing car during the night. The frontal airbags had not fired, which would have been consistent with either the car being parked and not running, or the side-swipe not producing the necessary accelerations for the…..

One of my first experiences investigating accidents occurred early in my career when I was working as a police officer. When a call came in involving a traffic accident and all units arrived on scene, the first assignment was to ensure that everyone involved was unhurt. Once the scene was secured, several basic investigating areas needed to be covered. One of these was to obtain an accurate roadway frictional coefficient. Back then, most of us relied on the use of a drag sled for this purpose. A drag sled is an apparatus that uses a weighted object with a tire…..

American English has a rich and complex history, having first incorporated words from many different colonization and immigration waves, and then in recent history having invented or created words for rapidly advancing technology.  A simple word like “fault” can mean entirely different things depending on the context and field of use.  A “fault” in electrical engineering may mean a short between two electrical lines of different polarities.  In control logic, a “fault” could be a measured or detected failed signal or logic state.  A “fault” in geology could mean the boundary between plates in the Earth’s crust.  “Fault” in the…..

When a car crash occurs and you are using any type of accident reconstructionist simulation software, you need to make certain that the data you’re inputting is accurate, because the old adage, “garbage in, garbage out”, holds true.  Put simply, an accident reconstruction simulation is only as valid as the inputs you enter.  If you have the wrong inputs, the simulation software will correctly crunch that data, but will result in an incorrect final determination. Recently, a client and I were discussing an accident reconstruction simulation I performed using the EdSMAC program and, more specifically, why my simulation was correct and…..
