ACTAR Test Preparation - Comprehensive (Online)  

Presented entirely online, this comprehensive course will assist you in preparing to take the ACTAR accreditation exam. It is suited for both crash reconstructionists and engineers. The course is divided into two parts – the theory portion and practical portion.

During the theory portion, you will watch a video lecture of each topic listed below and then take a quiz to check your understanding of the material. After all subject quizzes have been successfully completed, you will take a practice exam that is similar to the actual ACTAR theory exam.

Topics Include

  • Introduction to ACTAR
  • Mathematics/Trigonometry review
  • Airbornes
  • Momentum
  • Energy
  • Pedestrian collisions
  • Evidence interpretation
  • Commercial motor vehicles
  • Time-Distance analysis
  • Speed from tire marks
  • Basic photography

Should you have difficulty with any portion of the material, you will have telephone/internet access to the instructor, who will guide you through the material.

The second portion of the course will focus on the practical part of the ACTAR exam (the reconstruction).

You will view a video that covers the following topics:

  • Materials to bring to the second part of the exam
  • Calculating the center-of-mass of a vehicle
  • Drawing scale vehicles
  • Measuring departure angles
  • Measuring approach angles
  • Measuring departure distance
  • Properly reporting PDOF

After watching the video, you will be given two different crashes to reconstruct. The instructor will grade your work and then contact you to go over any weak areas.
