What to Expect from a Motorcycle Crash Reconstruction with Kilpatrick Forensics, PA

Posted on: December 7th, 2016 by admin No Comments

Kilpatrick Forensics, PA in North Carolina can perform motorcycle crash reconstruction services throughout the United States. Our owner, Gary E. Kilpatrick, has been an avid motorcyclist since 1969 and has obtained advanced motorcyclist training through the Motorcycle Safety Foundation (MSF). He is also a member of the American Motorcyclist Association, and the Harley Owners Group (HOG). He is uniquely qualified to perform motorcycle crash reconstructions. In fact, many of our staff are avid motorcycle enthusiasts and are familiar with the a motorcycles capabilities and limitations. Very few if any of our competitors have the intimate personal knowledge of motorcycles that we do.

Kilpatrick Forensics, PA can provide a thorough motorcycle crash reconstruction for you. Motorcycle crash reconstruction is similar in some ways to other types of vehicular crash reconstructions. It relies on the same basic principles of conservation of energy and momentum as other crash reconstructions. However, we are expertly and uniquely qualified to add in the specifics of motorcycle dynamics and rider control to our motorcycle crash reconstructions. Proper reconstruction of a motorcycle crash requires detailed knowledge of motorcycle dynamics with knowledge of how motorcycles react to rider input.

Our motorcycle crash reconstructions follow a reverse chronological order of events, working from the point of rest of the motorcycle and/or rider backwards to a point in time before the start of the crash sequence to when possible actions could have prevented the crash. We will give you a detailed account of what actually occurred as well as what alternatives were possible.

Motorcycle crash reconstruction requires knowledge of the 5 phases of the crash itself.

1) Perception – reaction. This is the phase where the rider perceives a hazard and decides on a response. Perception/reaction time is estimated at 1.1 to 1.5 seconds.

2) Avoidance – steering/braking. During this second phase, the rider typically engages in some type of an avoidance tactic like using the steering or the braking mechanisms on the motorcycle. Steering not only includes the use of the handlebars, but also body positioning and body lean. For braking the rider can use the front brake, the rear brake, or a combination of the two. Physical evidence at the scene combined with statements from witnesses can give clues as to what type of avoidance occurred.

3) Pre-Impact Sliding. During avoidance, riders may over steer or lock up the motorcycle brakes. Our motorcycle crash reconstruction will determine if the front wheel locked up during the crash. If so, the rider will almost certainly lose control and crash. If the rider loses control and crashes while braking, the motorcycle and rider usually separate and slide in the same trajectory they were moving in before the crash.

4) Impact. The motorcycle and/or the rider may collide with other objects like a vehicle, curbing, landscaping, or a guardrail. Damage caused by impact can be evaluated and combined with sliding distance to help determine the motorcycle’s speed during the crash sequence. This is a very important part of the motorcycle crash reconstruction.

5) Post-Impact Motion. After impact, additional movement to the point of final rest can occur. The rider frequently separates from the motorcycle and travels independently to the final point of rest. Analysis of post-impact travel distance can also determine speeds associated with the crash.

Not only do we thoroughly investigate these five points during our motorcycle crash reconstruction analysis, we provide the following services for you related to motorcycle crash reconstruction. They include, but are not limited to:

• Pre-impact and Post-impact Velocities,

• Delta-V Calculations,

• Vehicle Principle Direction of Force (PDOF) Calculations,

• Vehicle Energy Calculations,

• Acceleration, Distance, Time Calculations,

• Vehicle Falls, Flips, and Vault Airborne Calculations,

• Vehicle Trajectory,

• Cause Analysis,

• Human Factors,

• Motorcycle Safety,

• And much, much, more.

We Know Vehicle Crash Reconstruction

Posted on: October 2nd, 2016 by admin No Comments

Since 2003, Gary E. Kilpatrick, PE, DFE at Kilpatrick Forensics has been a service provider of motor vehicle crash reconstruction to our legal and insurance clients. Mr. Kilpatrick is a board certified forensic engineer by the National Academy of Forensic Engineers. He has extensive education, training, experience and certifications in vehicle crash reconstruction through North Carolina State University and Northwestern University’s Center For Public Safety. Mr. Kilpatrick is also a regional instructor for Northwestern University’s Center For Public Safety in motor vehicle crash reconstruction. He travels throughout the United States to investigate motor vehicle crashes, product defect and failure claims resulting in personal injury or wrongful death.

A motor vehicle crash reconstruction is the scientific process of investigating, analyzing and drawing conclusions about the causes and events surrounding a vehicle collision. We conduct in‑depth vehicle collision analyses to identify the cause of the collision and contributing factors such as the role(s) of the driver, vehicle(s), roadway and environment. The laws of physics and engineering principles are the basis for the analysis. Vehicle crash reconstruction provides vigorous analysis which an expert witness can present at trial. We will study weather and highway conditions to determine all of the contributing factors to the crash. Vehicle crash reconstruction can also be useful in developing recommendations for making roads and highways safer as well as improving the safety of motor vehicle design.

At Kilpatrick Forensics, we perform traffic crash reconstructions, ATV accident reconstructions, ROV accident reconstructions, motorcycle crash reconstructions, and tractor trailer crash reconstructions.

We provide a detailed and thorough investigation and analysis of motor vehicle crashes. Our engineers investigate crashes involving cars, light trucks, motorcycles, ATVs/ROVs and commercial heavy trucks. We participate in vehicle crash testing for research by attending the largest motor vehicle crash conference in the world. The purpose is to provide live real‑time motor vehicle crashes to observe how each vehicle responds dynamically and to observe pedestrian and occupant dynamics. Our engineers observe how motor vehicles, occupants and pedestrians actually respond to high and low speed crashes. It gives us great insight into an actual vehicle crash reconstruction.

ATV Accident Reconstruction

In 1990, the Specialty Vehicle Institute of America (SVIA) with the assistance of the American National Standards Institute (ANSI) published the first standards for ATVs. In 2001, 2007, and 2010, they updated these standards. An All‑Terrain Vehicle (ATV) is any motorized, off‑highway vehicle 50 inches or less in overall width with an unladen dry weight of 600 pounds or less. It is designed to drive on four, low‑pressure tires. The seat is designed to be straddled by the operator and there are handlebars for steering control. It’s intended for single occupant usage only. ATVs are subdivided in four categories. Our owner is an ATV enthusiast and knows very well how they function.

In 2008, the Recreational Off‑Highway Vehicle Association (ROHVA) with the assistance of ANSI began writing standards for Recreational Off‑Highway Vehicles (ROVs). The standard was completed and published in 2010. We follow the standards when performing an ROV accident reconstruction. For those of you who don’t know, an ROV is a motorized, off‑highway vehicle designed to travel on four tires. It’s intended for recreational usage and can have more than one passenger. When there’s an ROV accident, we can reconstruct it for you and help you decide what actually went wrong.

Motorcycle Accident Reconstruction

At Kilpatrick Forensics, our engineers love to ride motorcycles. We provide motorcycle crash reconstruction with a full knowledge of how these machines handle and their maneuvering characteristics. We will give you detailed information pertaining to the characteristics of a collision between a motorcycle and another motor vehicle or object. Motorcycles have different classifications and we are well versed in all of them.

Tractor Trailer Reconstruction

Tractor trailers are more complex vehicles than a passenger car or light truck, and crashes involving tractor trailer trucks are more complex than other vehicle crashes. We have the knowledge to determine if something went wrong with the road tractor and/or the trailer before the accident and how the crash materialized. We do a full and complete forensic style DOT inspection of both vehicles. We study weather and highway conditions to determine all of the contributing factor to the crash.

We work hard and will leave no stone unturned to bring you a thorough and complete vehicle crash reconstruction. If you need a vehicle accident reconstruction, call us today at our office at 336‑841‑6354.
