The 2011 RAV4 on the right of the image is moving at a speed of 65 km/h when it collides with the 2011 GMC Sierra pick-up truck travelling at 56 km/h coming from the left.
There are two dummies representing an average size man (red jacket) and a small woman (blue T-shirt) in the rear seat.
At impact the dummies continue to move forward, loading and stretching the seat belts.
The lower portion of the lap belt, close to the door slides over a steel edge on the seat frame. Because the belt is under a high load, it tears and separates.
