Commercial Vehicle Crash Investigation - Level II   

Print Course Description Download Registration Form

SECOND IN THE COMMERCIAL VEHICLE CRASH INVESTIGATION SERIES

Designed to further enhance the knowledge and skills you acquired in IPTM’s Commercial Vehicle Crash Investigation–Level I course, this class focuses on a detailed analysis of commercial vehicle systems and dynamics along with the application of your findings to the crash reconstruction.

We will begin by analyzing the ABS air brake system on commercial motor vehicle (CMV) truck-tractors and trailers by conducting tests to determine average air brake chamber pressure. You will participate in a “hands-on” field inspection as we conduct brake tests with a CMV.

We’ll teach you how to construct free-body diagrams and formulate equilibrium equations to determine the range of weight distribution on the axles. We will also examine quasi-static and dynamic rollover propensities and conduct an analysis of suspension spring rates.

After a review of high and low speed off-tracking, we will show you how to derive the equations for establishing maximum off-track distance. You will also learn how to interpret and analyze rotational motion that may be present in a CMV crash.

Finally, we will discuss the different types of transmissions used in today’s commercial motor vehicles and teach you how to obtain the range of speeds for the vehicle based upon the gear position at the time of the crash.

Topics Include

  • Tractor-trailer ABS air brake system
  • Hydraulic brake systems in commercial vehicles and how fluid pressures are boosted
  • Quasi-static and dynamic rollover propensities and liquid loads
  • Axle weight analysis and load reconstruction
  • Off-tracking
  • Speed from gear ratio
  • Rotational mechanics
  • Field inspection

What Our Students Are Saying

  • “Greatly increased my knowledge to deal with commercial vehicle crashes and the data involved.” – Dep. T.S.
  • “Practical outdoor exercises were invaluable to aid in understanding theories learned in class setting. Fantastic course with great, very knowledgeable instructors!” – Dep. L.T.
  • “Very well put together course. Instructors are very knowledgeable in this field and are able to clearly present this material to the level of class participants.” – Ofc. W.D.
  • “Great course. Definitely increased my knowledge and awareness of the data collected and its importance.” – M/Ofc. R.L.
  • “The knowledge base of the instructors on this topic is amazing. They both completely took the time to make sure the class captured the information. I especially benefitted from the ABS calculations and EDR material. Thank you for the class and your time.” – Ofc. T.H.
  • “The most interesting reconstruction course I have taken in 6 years of attending recon courses. I am recommending the other guys on my team to come to this class.” – Ofc. M. T.

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 info@iptm.org 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.
