One of the most complex categories of crash are those involving commercial vehicles.  These crashes usually generate significant and dramatic roadway physical evidence along with extensive collision damage to the vehicles.  In the modern trucking environment, the investigation needs to include an analysis of on-board electronic devices that may provide critical pre and post-crash evidence to the investigation.

An in-depth investigation should include:

  • Engine control module download and analysis
  • Brake condition and brake force calculations
  • Driver logbook and fatigue factor analysis
  • Complex tire mark analysis on the roadway
  • Engine casualties or other mechanical condition that could have an effect on the crash
  • Fire cause and origin
  • Overloading and loss of stability issues
  • Compliance with the Federal Motor Carrier Safety Regulations
  • Driver strategy and tactics – including driver training issues
  • GPS and satellite communication analysis

Introtech staff has been extensively trained in the proper interpretation of the unique physical evidence generated in a commercial vehicle crash.  Our specialized training in commercial vehicle crash evidence, human factors and commercial vehicle components have been obtained from the most prominent schools in the field including; Northwestern University, Bendix Spicer Foundation Brake LLC, National Transportation Safety Board Academy, The Ohio State Highway Patrol Academy, and The Institute of Police Technology and Management.

We have the ability to properly image and analyze the electronic data from on-board engine control modules from a wide variety of commercial diesel engines.  In addition we have our own in-house diesel engine expert with expertise in General Motors/Detroit, Cummins and Caterpillar engines.   When necessary we incorporate experts in commercial driving procedures and standards in order to expand upon the human factor investigation.

All of this expertise and experience is applied to the unique aspects of commercial vehicle crash investigation.
