Electronic Stability Control (ESC) has been proven to be one of the most effective safety technologies, reducing serious crashes substantially. In Sweden the first attempt to stimulate the sales of ESC started in mid 2003. By using several market oriented methods the penetration rate on new cars reached over 90% 48 months later and is by late 2008 around 98%. In this paper, the methods to increase fitment of ESC, are presented, including actions from the government, administrations, insurance companies and the automotive sector. The results show that a structured implementation strategy can be very successful.
