What happens to vehicles and their occupants in crashes is determined by science. "You can't argue with the laws of physics, " says Griff Jones, an award-winning high school physics teacher who goes behind the scenes at the Institute's Vehicle Research Center to explore the basic science behind car crashes.

Understanding Car Crashes: When Physics Meets Biology
Why do some car crashes produce only minor injuries? How can a single crash of a car into a wall involve three separate collisions? Griff Jones, award-winning science teacher, returns to the Insurance Institute for Highway Safety's Vehicle Research Center to answer these questions and to examine the laws of nature that determine what happens to the human body in a crash.
