Airbags and seatbelts react differently during a collision depending on the size of person behind the wheel and how close they sit to the steering wheel when driving. These impact tests are called OOP (out of position) procedures. The Hybrid III 5th Percentile Female Dummy is only 5’ (152cms) tall, weighs just 50kgs and is used to measure the forces found in frontal impact crashes.
