Automobile Accidents

Our engineers have extensive experience with all types of motor vehicle accidents


Knott Laboratory has investigated thousands of motor vehicle accidents; from single vehicle roll-overs to multiple car pile-ups. While we have extensive experience with all types of motor vehicle accidents, no two accidents are the same. Knott Laboratory engineers are able to draw from their extensive experience to answer complicated questions and to identify key issues that need to be addressed through litigation.

Knott Laboratory engineers have specialized training, education and experience to thoroughly and accurately investigate all types of motor vehicle accidents. We have access to state of the art technology and computing which help our engineers to accurately determine the speeds of the vehicles and their motion both before and after a collision. Knott Laboratory also has the ability to download a vehicle’s “black box” which often contains valuable information related to the vehicle’s speed and driver’s actions in the moments just before impact. While accessing the black box data is helpful, it is the proper interpretation and analysis of all the available information that results in a thorough and accurate reconstruction.
