 Essentials of Traffic Crash Investigation
by Neil F. Robar and George L. Ruotolo

Essentials of Traffic Crash Investigation is the foundation and the first in a three-part series of texts designed to develop the skills of police officers—transforming them from those who simply fill out crash reports into ones who investigate and ultimately reconstruct crashes. The goal of this book is to familiarize officers with crash scene and crash vehicle evidence, to detail the procedures to document that evidence, and to interpret the meaning of the evidence. The 13 chapters are arranged in a logical investigative order and follow the sequence of IPTM’s At-Scene Traffic Crash/Traffic Homicide Investigation course curriculum. In addition to a substantial glossary of terms and several useful references in the Appendix, you will find the mathematical examples and calculations worked in both US and SI measurements.

For anyone interested in learning the basics of crash investigation—whether in a classroom setting, as a desk reference, or teaching tool—this book is certain to be a valuable aide and future reference guide.

The book contains the following chapters:

  • Introduction to Traffic Crash Investigation
  • Series of Events
  • Mathematics Review
  • Documentation of Roadway and Scene Evidence
  • Vehicle Inspections and Evidence from the Vehicle
  • Math Fundamentals for Crash Reconstruction Working with F and Mu (µ)
  • Calculating Speed and Combined Speed Equations
  • Time Equations and Distance Equations To or From a Stop
  • Introduction to Critical Speed
  • IPTM blueblitz Traffic Template
  • Measuring and Diagramming
  • Occupant Kinematics
  • Trial Preparation and Courtroom Testimony

About the Authors:

Neil F. Robar is a 20-year veteran of the Hollywood (FL) Police Department where he began his career as a patrol officer, rose to the rank of Lieutenant and retired as a Captain. During his tenure, he commanded the Fatal Accident Unit, and later, the Detective Bureau. In 1980, he became IPTM’s first employee and trained police all over the globe until his retirement in 1994, when he entered private practice as an Expert Witness in collision reconstruction. While he consulted on all types of vehicle collisions, Mr. Robar specialized in crashes involving motorcycles. His expertise was sought throughout the United States and he authored several articles and booklets dealing specifically with motorcycle crashes. He also co-authored the 1st and 2nd editions of Advanced Traffic Crash Analysis and Conservation of Linear Momentum 360-Degree Method with George Ruotolo.

George L. Ruotolo is President of Ruotolo Consulting, Inc. As a recognized Expert Witness, author, and professional police trainer, Mr. Ruotolo has been providing traffic collision consulting and reconstruction services for more than 35 years throughout the U.S. and internationally. During that time, he reconstructed over 3,400 fatal and serious personal injury crashes, provided expert witness testimony in more than 150 trials, and offered sworn deposition testimony in approximately 300 civil and criminal cases across the U.S. in both state and federal jurisdictions. Accredited by ACTAR and the Florida Bar Association, Mr. Ruotolo provides “CLE” credit seminars to both attorneys and paralegals in the field of crash reconstruction. During his career with New York State and IPTM, he developed curricula and trained thousands of law enforcement officers and administrators around the globe on topics such as traffic crash investigation/reconstruction; DUI/DWI, including breath test certification; RADAR certification; police executive management training; police policy and procedure; and police instructor certification. Through the University of North Florida—IPTM, Law and Order Magazine and the Law Enforcement Executive Forum, Mr. Ruotolo authored and published numerous textbooks, booklets, and articles on topics pertaining to linear perimeter measurement, interpreting vehicle damage, courtroom testimony, report writing, and police pursuit policy, to name a few. Several of these are available via Videos on Demand through IPTM’s online training system. He also co-authored the 1st and 2nd editions of Advanced Traffic Crash Analysis and Conservation of Linear Momentum 360-Degree Method with Neil F. Robar.
