Briefly, the test involves a 50 km/h impact of a vehicle equipped with a Hybrid III 50th percentile male driver and an HIII 5th percentile female front passenger. Aimed particularly at reducing injuries to the elderly, the test sets a 42 mm ThCC threshold that will be strengthened to 34 mm for the HIII 5F in 2020 (via the 01 series amendments).
