The Hybrid III is the standard crash test dummy as of the beginning of the twenty-first century. It was initially only a 50th percentile male (equal in height and weight to the average North American male).

The original 50th percentile male Hybrid III's family expanded to include a 95th percentile male, 5th percentile female, and three-year-old and six-year-old child dummies.

Hybrid III, the 50th percentile male dummy which made its first appearance in 1976, is the familiar crash test dummy, and he is now a family man. If he could stand upright, he would be 168 cm (5'6") tall and would have a mass of 77 kg (170 lb). He occupies the driver's seat in all the Insurance Institute for Highway Safety (IIHS) [1] 65 km/h (40 mph) offset frontal crash tests. He is joined by a "big brother", the 95th percentile Hybrid III, at 188 cm (6'2") and 100 kg (223 lb). Ms. Hybrid III is a 5th percentile female dummy, at a diminuitive 152 cm (5 ft) tall and 50 kg (110 lb). The two Hybrid III child dummies represent a 21 kg (47 lb) six year old and a 15 kg (33 lb) three year old. The child models are very recent additions to the crash test dummy family; because so little hard data are available on the effects of accidents on children, and such data are very difficult to obtain, these models are based in large part on estimates and approximations.
