Accident Reconstruction

Our accident reconstructionists use state-of-the-art technology in reconstructing accidents


Knott Laboratory provides expert accident reconstruction and analysis for attorneys and insurance professionals on a nationwide basis. Our forensic engineers have investigated and reconstructed thousands of vehicle accidents, including low-speed accidents, front, rear and side impact collisions and multi-vehicle pile-ups; tractor-trailer and trucking accidents; motorcycle accidents; intersection accidents; bicycle accidents; pedestrian accidents; recreational vehicle (such as ATVs) accidents and train and railroad crossing accidents.

Our forensic engineers also have extensive experience with construction equipment accidents, crane accidents and forklift accidents.

Our forensic engineering experts are licensed and registered professionals and are well qualified to simplify complicated issues and to communicate them clearly and effectively in the courtroom. In the over 30 years Knott Laboratory has been in business, our forensic engineers have evaluated several thousand vehicular accidents, and have been qualified as expert witnesses in over 500 cases in depositions and in state and Federal courts.

Our accident reconstructionists use state-of-the-art technology in reconstructing accidents. We utilize data information from GPS records, cell phone records and Event Data Recorders (EDR) from commercial trucks. We also use state-of-the-art software, such as PC-Crash and Bosch CDR, to analyze vehicle dynamics and speeds.

Our forensic engineers also produce sophisticated animations, graphics and interactive applications designed to communicate our engineering analysis and opinions to the judge and jury or during depositions, mediations, or arbitrations.

We are qualified to investigate:

  • Calculation of vehicle speeds
  • Braking and steering capabilities
  • Impact energy
  • Impact configuration
  • Crash severity
  • Crashworthiness
  • Vehicle dynamics
  • Avoidance scenarios
  • Driver perception and reaction
  • Visibility analysis
  • Occupant kinematics
  • Occupant restraint analysis
  • Component failure analysis
  • Mechanical design
  • Mechanical equipment failures
  • Construction equipment failures
