The National Safety Council's Defensive Driving Course (DDC) was evaluated by two methods -- comparison of self-reported accident and violation rates from the year before and the year after DDC, and comparison of the 'after DDC' rates with those reported by other drivers who were not exposed to DDC but were driving at the same time. Official state records were also collected. Information was obtained from 8,182 DDC graduated (study group) in 26 states who completed a survey describing their accident and violation histories for the 12-month period before DDC. One year later, 72% (5,921) of these drivers responded to a similar self report for the 12-month period after DDC. DDC graduates responding to the recontact questionnaire reported significant reductions of 32.8% fewer accidents and 24.9% fewer violations in the year after DDC as compared to the year before.
