At Scene Collision Investigation - Level I

The first level of instruction in accident reconstruction training.  Attendees are law enforcement, insurance investigators, engineers, and others crash investigators.  This week long (40 hours) class will introduce students to the importance of a quality investigations using the following techniques:

  • Identify and document crash evidence
  • Skid mark analysis
  • Report writing
  • Scale diagramming
  • Scene photography
  • Introduction to time and distance analysis as it applies to crash investigations
  • Introduction to airborne equations

Advanced Technical Collision Investigation - Level 2

The second level of instruction in accident reconstruction training.  Level I is a prerequisite for this course.  During this two week (80 hours) of course instruction, the following topics will be covered:

  • In depth coverage of time and distance analysis as it applies to crash investigations
  • Advanced airborne equations
  • Crush damage analysis
  • Linear parameter measurement system
  • Vehicle dynamics
  • Occupant kinematics
  • Conservation of linear momentum
  • Vehicle system failures
  • Introduction to automobile vs. pedestrian collision analysis 

Traffic Collision Reconstruction - Level 3

This accident reconstruction training class is an 80 hour course designed for working automobile collision investigators who have completed Level I and II.  Included in this course are the following topics:

  • Energy
  • In depth application of time and distance analysis as it applies to crash investigations
  • Formula derivations
  • Introduction to commercial vehicle and heavy truck collision reconstruction
  • Introduction to Event Data Recorders (EDR) and their applicability in collision reconstructions
  • Introduction to the use of unmanned aerial aircraft (drones) used in collision reconstructions 

Automobile vs. Pedestrian Reconstructions

This accident reconstruction training course is a 40 hour course designed for those who have completed Level I and II.  This course will provide information to students regarding reconstruction of collisions involving vehicles, pedestrians, and bicycles.  Included in this course are the following topics:

  • Formulas for speed estimates from pedestrian vaulting, fall to ground and slide to rest, or roll and slide to rest locations
  • Applications of scale diagramming and laser mapping of collision scenes
  • Time and distance analysis as it relates to pedestrian and vehicular motion
  • Vehicle damage analysis and its use in determining collision movements and forces
  • Study of injury analysis and pedestrian kinematics with respect to vehicle frontal geometries 
  • Algebraic and mathematical hierarchies 


In addition to the listed topics, weather permitting, one day will be devoted to live crash testing where attendees will apply covered topics investigating staged collisions using an anthropomorphic dummy.  All crash tests will be documented with video and photography which will be provided to all attendees at the conclusion of the course.  

Motorcycle Collision Reconstruction

This accident reconstruction training course is a 40 hour course.  Attendees must have completed an Advanced Technical Collision Investigation-Level II course prior to taking this course.   


The following topics will be covered:

  • Interpreting marks level by motorcycles at crash scenes
  • Sliding motorcycle friction values
  • Pedestrian friction values
  • Motorcycle brake systems
  • Articulated vehicle issues
  • Crush damage analysis using frontal fork deformation
  • Momentum / energy in collisions
  • Center of mass calculations


Weather permitting, one day will be devoted to motorcycle acceleration and brake testing.  Testing will be done of motorcycle sliding. 

Investigating Commercial Motor Vehicle Crashes

This accident reconstruction training class is a 40 hour course which covers the investigation of collisions involving semi-tractor trailers, recreational vehicles, truck and trailer combinations, and other heavy equipment.  Prerequisite to attend the course is Advanced Technical Collision Investigation - Level II.  The course will discuss:

  • Commercial vehicle types
  • Part nomenclature of trucks and trailers
  • Air brake systems
  • Federal Motor Carrier regulation
  • Brake force calculation for air brake systems
  • Center of mass calculation of articulated vehicles
  • Coupling devices 
  • Introduction to engine control modules and other electronic data contained in commercial vehicles
  • Collision dynamics and energy calculations
