Revolutionary Euro NCAP car safety tests were launched 20 years ago, and in 2015, 15,000 fewer car occupants were killed and seriously injured. Twenty years on, 9 out of 10 cars sold on the European market hold a Euro NCAP rating. In 2016, Thatcham Research estimates that advances driven by rigorous testing has helped deliver a 63% per cent reduction in car occupants killed and seriously injured.
