The accurate reconstruction of vehicle collisions is essential for the understanding of many forensic cases we analyze. The engineers with Quality Forensic Engineering, LLC have extensive experience in vehicular crash testing and specialized training in automobile collision reconstruction. This experience, along with computer simulation tools, allow us to accurately reconstruct collisions and convey the results to clients and juries.



Engineers with Quality Forensic Engineering, LLC have specific training and many years of experience in the reconstruction of collisions involving heavy trucks and tractor-trailer rigs. This includes the download and analysis of the tractor’s Engine Control Module (ECM) for important information such as speed and braking, as well as the testing and evaluation of airbrake systems.


It is important to be familiar with the issues associated with bicycling, including dynamics and safety issues. In addition to analyzing many vehicle vs bicycle collision cases, we have had extensive training on crash testing interactions between vehicles and bicycles. We have been involved in the forensic evaluation of numerous vehicle vs bicycle collisions.


Motorcycle accidents can be the result of weather, poor bike maintenance, poorly maintained roads and construction, driver negligence, driving under the influence, ignoring laws and road signs, and road rage. Serious injuries can result. When your case involves a serious accident, you need an engineer you can trust. Our engineers are here to help.


Collisions between vehicles and pedestrians can result in serious injuries to pedestrians, even at low speeds, as the human body is unprotected in these situations. It is very important to understand the issues surrounding the incident including speed, visibility, impact orientation, and lighting conditions. Our engineers have considerable training and experience in investigating and analyzing vehicle vs pedestrian collisions.

Occupant Kinematics

The analysis of the movement of bodies in a vehicle during a collision is known as occupant kinematics. As part of a vehicle collision reconstruction analysis, we can also analyze the movement of the occupants within the vehicle to determine what areas they would contact and what forces would be involved. This can be used to assist a biomechanical engineer in the analysis and evaluation of injury causation.


It is well known that vehicles leave the roadway for a number of reasons, and as such it is important the roadside be designed and maintained in a safe manner. Many advances have been made in the last 40 years regarding the safety of our roadsides, and our CEO / Senior Engineer has been involved in a number of these. If your case involves interaction with roadside appurtenances such as guardrails, bridge rails, or sign supports, it is important to know the role the design and placement of these features played in the event. Our engineers are extensively trained in analyzing roadside conditions and required safety measures that should or could have been implemented and the effectiveness of these measures.


We have significant experience in the design, crash testing, and implementation of products which make our roadsides safer for travelers. These products include guardrails, guardrail terminals, bridge rails, crash cushions, breakaway sign supports, and other safety devices found along roadways. Our CEO is one of the leading experts in the United States in guardrail safety and he is often consulted regarding the design, implementation, and effectiveness of these types of devices.

Construction Zones

Consideration for the safety of people as they travel through construction zones is an important part of the planning process. Regulations and guidelines are in place for the development and implementation of Maintenance of Traffic (MOT) plans for construction projects. In addition to experience developing and testing safety devices used throughout construction projects, we are certified in the State of Florida to develop and implement these plans. We have considerable experience in evaluating MOT plans and construction sites to determine compliance with standards and overall effectiveness.


Using years of industrial work experience as the basis, our engineers are able to provide detailed and thorough engineering analyses and accident investigations. Industrial accidents can include a broad range of issues including Lock Out/Tag Out, Machine Guarding, Personal Protective Equipment, Conveyors, Forklifts and other Material Handling Devices, and Construction Equipment. We have the knowledge and experience to piece together complex and varied aspects of the accident and present cohesive conclusions.


An Airbag Control Module (ACM), commonly referred to as a “Black Box”, is a device on passenger vehicles that can store information when an accident occurs. Some manufacturers have had black boxes in their vehicles for many years now while others added these features more recently. Most manufacturers have one or more modules that can store data related to an accident and these modules have different capabilities depending on the make, model, and year they were installed. The ACM may contain information that is relevant to your case, even if the airbag did not deploy! This is a potentially important piece of evidence in your case and calling Quality Forensic Engineering, LLC can help you retrieve and/or interpret that evidence.

Tractor Trailer Electronic Control Modules (ECM)

ECMs are devices on larger commercial vehicle engines that help control and monitor engine functions.  One of the benefits of these systems is they can store information related to accident reconstruction when collisions occur.  While some manufacturers have minimal information, others have a treasure trove of detail that is truly invaluable to your case.  Available information varies between the manufacturers, model, and year, so it’s important to know the various system capabilities.  As with the black boxes on passenger vehicles, ECMs may have important evidence for your case so call Quality Forensic Engineering, LLC to help retrieve and/or interpret that evidence.

gps (1)

Global Positioning Systems (GPS)

GPS’s have been around for some time now, and it’s becoming very common for vehicles to have these systems both as original and aftermarket equipment.  Many of these systems store information on them as they are programmed to store a “bread-crumb” trail which includes time stamped speed and location information.  Though the resolution on these systems is not nearly as detailed as other black box systems on tractor trailers and automobiles, the time stamped speed and location can be critical in some cases.  Always check to see if any of these systems are on vehicles from your cases and remember to call Quality Forensic Engineering, LLC to help you analyze and retrieve this excellent source of evidence.

Digital Video Systems

Many new technologies, such as digital video systems, provide additional useful data which can be analyzed by forensic engineers.  These systems are typically aftermarket devices that are added to both private and commercial vehicles.  Different systems store various information that can include multiple video views, speed, brake usage, accelerometers, GPS information, and more.  If pictures are worth a thousand words, how valuable is video from the vehicle in your case?  For more information and assistance with these types of systems, remember to call Quality Forensic Engineering, LLC to help you to analyze and retrieve this excellent source of evidence.



The engineers at Quality Forensic Engineering, LLC have educational backgrounds in mechanical, civil, and industrial engineering. This education, combined with years of design experience, give us a unique perspective in the evaluation of incidents which may be related to the design of a product. This experience ranges from the development and crash testing of roadside safety appurtenances to the design and at-sea testing of large material handling systems.


Slip, Trip, and Fall

All falls are not equal and can be complex events. Analysis of the kinematics of the fall is as important as understanding the context of the fall and other factors that may have played a part in the fall happening in the first place. Using tools such as the English XL Variable Incident Tribometer allow us to use peer reviewed, accepted scientific methods to measure and evaluate the slip resistance of a floor surface. Then, using other analytical tools such as applicable standards, codes, and guidelines along with our knowledge and experience, our engineers are able to undertake a thorough investigation and determine conclusions that are understandable and based on facts.


When looking for authoritative sources regarding definitions of best practices or even requirements by law, ANSI, ASTM, SAE, ASME, and UL are excellent resources. These standards, guidelines, and codes have been written by members of various industries in an effort to share lessons learned and establish minimum expectations regarding processes and safety. Our engineers use these tools and their years of experience to develop a detailed analysis in order to provide answers in the case.


The Occupational Safety and Health Administration (OSHA) and the Americans with Disabilities Act set forth laws and codes to help ensure that our workplaces, such as construction, agriculture and mining, are using best practices and are as safe as possible. These codes define requirements for issues like Walking-Working Surfaces, Powered Platforms, Manlifts, Vehicle Mounted Work Platforms, Forklifts, Fall Protection, Warnings, and Multiple Employer Workplaces. The ADA also includes requirements for accessibility and reasonable accommodations in public areas and workplaces. We have the real world and consulting experience necessary to provide analyses of these complex issues and present conclusions that help define the issues of your case.


Places where the public is invited to conduct business, such as retail stores, restaurants, or offices are subject to the same kinds of potential hazards and issues found in industrial workplaces. Some of the most common issues center around slips, trips, and falls, parking lots, and interaction with merchandise and fixtures. Many of the same resources used for more industrial facilities are applicable in the public forum as well. Our engineers draw from their own experience and knowledge to provide analyses and answers regarding these everyday exposures.
human-environment-interaction (1)


If you look at any accident involving personal injury, there is a common element present in each of them, the human element. Being able to provide analysis covering the human factors aspect of an accident is critical. Human factors and environmental interaction can take the form of perception and reaction times and actions, pedestrian and walkway visibility and conspicuity, or even the effectiveness of a warning sign. Understanding how people interact or foreseeably interact with their environment, conditions, vehicles, and facilities, to name a few, is a critical piece in the overall analysis of an accident. Our engineers have the experience to make sure these important elements and factors are addressed in the overall analysis of a case.


Theme Park and Recreational facilities can sometimes present real hazards and dangers to the patrons. With everything from ride and safety restraint design to maintenance of rides and of the facility and grounds, there are many common safety and engineering issues present in these venues. Slips, Trips, Falls, ride operations and procedures, and guarding and warnings are all engineering issues that require in-depth understanding and expertise. Our engineers have the experience to provide detailed analyses and conclusions and answers for your case.
