On January 1, 2003, the motor vehicle management system in Korea was transformed from government's vehicle type approval to manufacturer's self-certification. The motor vehicle recall system with self-certification is an essential mechanism to place the liability of the vehicle defects on manufacturers and hence protect consumers from automobile accidents. This study provides a methodology to measure the benefits of motor vehicle recall system in two categories: benefits of reduction in traffic accidents and benefits of severity reduction in traffic accident. Applying the proposed methodology, the benefits of implementing motor vehicle recall system in Korea were estimated. It was estimated that 745 traffic accidents, 12 fatal accidents, and 1473 injury accidents were respectively reduced in 2002 due to implementation of motor vehicle recall system.
