Collision Investigation - Advanced

This class is 80 hours in length and expands on the teaching of the Basic course, and provides new material.  Upon successful completion of this course, participants will be able to:

  • Understand advanced vehicle accident concepts of pre and post-accident vehicle speeds and paths
  • Vehicle conditions related to accidents
  • Demonstrate use of appropriate formula applied to specific accident situations

To register for the course, contact your Training Manager to assign the training to you via Acadis.

Upcoming classes are listed below.  Registration does not guarantee acceptance into the class.  Selections will be completed four weeks prior to the class; those accepted into the class will receive a notification at that time.

If classes are full, or not available, please complete the Course Interest Survey.  This is not a waiting list, but instead helps us see if there is enough interest to create another class.  If we schedule a session, we will contact everyone who has completed the survey and request that registration be completed.

Successful completion of Collision Investigation Basic course.
