Advanced Traffic Crash Investigation - Online-Accelerated   

Online instructor-led course conducted over two consecutive weeks.

You must register at least 7 business days before the start date if you're in the U.S. and 21 if you're outside the U.S.

Presented entirely online, this course builds upon the theories and techniques learned in IPTM’s At-Scene Traffic Crash/Traffic Homicide Investigation course, and will delve into the advanced concepts of traffic crash investigations.

More complex vehicle dynamics like acceleration/deceleration, factor, rate and airborne situations will be explored. You will learn to estimate speeds from falls, vaults, and flips and the calculation of kinetic energy and linear momentum. You’ll also learn to evaluate vehicle lamps, tires, and damage to help determine vehicle behaviors during the collision.

Much of the coursework will be spent using acceleration/deceleration factors and perception/reaction times to determine time/distance relationships for colliding vehicles.

Topics Include

  • Speed estimates from kinetic energy, skidmarks, scuffmarks and airborne situations
  • Vehicle dynamics and motion
  • Time, distance, and motion equations
  • Conservation of momentum equations
  • Center of mass calculation
  • Vehicle lamp examination
  • Tire damage evaluation
  • Vector sum analysis


You must have completed IPTM’s At-Scene Traffic Crash/Traffic Homicide Investigation course, or its equivalent, and understand and be able to apply the following areas of knowledge:

  • The formulas learned in the At-Scene Traffic Crash/Traffic Homicide Investigation course
  • The series of events of a traffic crash
  • Identification of physical evidence of a traffic crash and identification of tire marks
  • Determination of friction and adjusting it for braking efficiency and grade
  • Calculating equivalent energy speed loss from skid marks (minimum speed formula)
  • Combining speeds from two or more surfaces or events
  • Calculation of speed from critical speed yaw events
  • Measurement of evidence at a scene and constructing a scale diagram with a traffic template or computer aided drafting software


Law enforcement and private traffic crash investigators, claims adjusters, engineers, attorneys, safety officers, military investigative personnel, animators and graphic designers

Course Length

80 hours


For Florida Officers, this course will not qualify for Salary Incentive Credit for FDLE course “Traffic Homicide Investigation.”

IMPORTANT: Required materials will be shipped to you before the first day of class.

Online Details

Online environment: This course is interactive, instructor-led, and divided into daily modules. At the end of each day, the current module will close and a new module will open. Each student must successfully pass the quiz to progress to the next day of the course. The entire class progresses through the materials together like traditional classroom training; there are no provisions to skip modules or work ahead of the rest of the class. Class activities will take place Monday through Friday (only) for two consecutive weeks. Each day will require approximately 6-10 hours of class.

This is not a self-paced course. Although there are no specific times that you must be online, you will be required to complete assignments each day by midnight. Video lectures will be available each day beginning at midnight and learning activities must be completed each day.

The instructor will be available by e-mail and discussion forums throughout the course. He/She will be your guide and will assist you with questions every step along the way.

Computer requirements: You will complete the course entirely online. A dependable broadband internet connection with a Windows or Mac computer and Adobe Acrobat Reader (free download) are required.

Schedule Changes

This schedule is subject to change without notice. If you have not received an official confirmation email prior to the first day of class, please contact us at (904) 620-4786 or before traveling or making airline reservations.

Registration and Fees

Full payment must accompany all registrations. You may register online and pay with your Visa, MasterCard, Discover or American Express credit card, or you may download a Registration Form and mail it to IPTM with a check.

Cancellation/Refund Policy

Complete the Cancellation Request Form and return it to IPTM. No telephone cancellations will be accepted. A 20% administrative fee will be assessed to all refunds if the cancellation request is received within 14 days of the course start date. In lieu of a refund, student substitutions can be made or a credit can be issued for a future course. No refunds will be given for no-shows. If materials for an online course were sent to the student, the appropriate materials and shipping costs will be deducted from the refund amount. Materials may be returned to IPTM in their original condition at the student's expense. Once IPTM has received and inspected them, the refund will be processed.

Due to the automated format of online independent study courses and Videos on Demand (VoDs), no refunds or substitutions can be made after registration.

Course Confirmations

A minimum number of registrations must be received for an in-person class to run as scheduled. When the minimum criterion has been met, written confirmation will be emailed to you. Please do not travel or make airline reservations until you receive written notification confirming that the course will run as scheduled.

Transportation and Lodging

Most locations are served by several major airlines. Transportation, food and lodging are the responsibility of the student. For information on training locations, please visit our Locations page or call us at (904) 620-4786. For courses in Jacksonville, the University of North Florida maintains a list of area hotels on the Campus Travel Management page.
