Advanced Traffic Crash Investigation (Online)   

Online instructor-led course conducted over ten consecutive weeks.

You must register at least 7 days before the start date if you're in the U.S. and 14 if you're outside the U.S. International students may also incur additional shipping fees.

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 weekly modules. At the end of each week, the current module will close and a new module will open. This way, the entire class progresses through the materials together, just like classroom training. There are no provisions for you to skip modules or work ahead of the rest of the 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 week by the deadlines posted within the course. Hence, you must be committed to the course and invest the time necessary for successful completion. You should plan to dedicate an average of five to eight hours per week to the course activities.

The instructors will be available by email and on discussion boards throughout the course. They will be your guides and will assist you with questions and advanced discussions at 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. 

This course is not eligible for certificate discounts.
