Inspection and Investigation of Commercial Vehicle Crashes

This intensive course will cover the unique characteristics of commercial motor vehicles and the special dynamics at play when one is involved in a collision.  

Detailed information of the nomenclature and operation of commercial motor vehicles will provide you with a level of competence needed to perform an adequate post-crash inspection of the vehicle.  To reinforce the concepts presented, you will conduct “hands-on” exercise inspections and vehicle testing during the course.

Topics include:
•  Tractor-trailer nomenclature 
•  Brake systems: configuration and operation
•  Wheels, rims and tires
•  Steering suspensions and frames
•  Trailer coupling devices - fifth wheels
•  Tachograph charts - log books
•  Vehicle inspections
•  Center of mass determinations
•  Skid mark measurements and speed analysis
•  Jackknifing
•  Hydroplaning
•  Rollover
•  Vehicle dynamics in braking
•  Weight shifting

Prerequisite:  This course is designed for traffic crash investigators who have completed, at a minimum, IPTM’s At-Scene Traffic Crash/Traffic Homicide Investigation course or its equivalent.  You should have a good working knowledge of the techniques and applications of the formulas presented in the basic course, as the presentation of mathematical formulas will build upon techniques already used by investigators.

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