Crash Test Dummy
A crash test dummy is an instrumented human-shaped model used in crash tests to measure the forces a real occupant would experience.
What is Crash Test Dummy?
Dummies come in adult, small-adult and child sizes. Well-known families include Hybrid III, THOR, WorldSID and the Q-series child dummies. Sensors record head, neck, chest and leg loads during the impact. Newer test programmes use more advanced dummies to better represent different body sizes and older occupants.
How it works
Accelerometers and load cells inside the dummy measure forces, which engineers compare with injury limits.
Why it matters for your car
A good rating depends on how the dummy readings compare with injury thresholds, not only on the car staying intact. Results for one dummy size do not cover every body type.
