Howsafeisyourcar.com.au inlcudes ratings from the Australasian New Car Assessment Program (ANCAP) and Used Car Safety Ratings (UCSR).
Whichever rating system you use, the more stars the better. Both programs award a maximum of 5 stars.
The latest UCSR are based on statistics collected from car crashes in Australia and New Zealand between 1990 and 2017, where someone was killed or seriously injured. Over eight million police reported crashes were analysed in the latest UCSR.
