The present research focused on evaluating an effect of training program for elderly drivers based on coaching method.　A before-after comparison of their driving performance, self-evaluation and instructors’ evaluation was conducted in three driving schools in Japan with 120 participants(117 male and 3 female), who were divided into a training group and a control group.　The driving performance, the driver’s face and traffic scene were recorded by in-vehicle data recorder and video cameras.　After driving through a driving school course, the participants in the training groups, usually four participants in each session, watched videotaped scenes of their own driving mainly at intersections and discussed their driving style.　Driving instructors supported the discussion with relevant comments and questions to the participants.　The training demonstrated a marked effect immediately after and a certain effect one month after the training on both driving performance and instructors’evaluation.　The participants demonstrated more searching head movements after the training than before the training.　They drove at lower speeds at uncontrolled intersections both with restricted visibility and with stop sign after the training.　The effects on driving performance were maintained even after one month.　Instructors’evaluations were improved immediately after the training and were stable even after one month.　Self-rated driving performance declined immediately after the training, but had almost recovered after one month.
