To prevent an accident due to a dangerous operation by detecting a dangerous operation by another vehicle.SOLUTION: An on-vehicle device performs: measuring an inter-vehicle distance from another vehicle on a front/rear side (step S3); determining whether an inter-vehicle distance is equal to or less than a predetermined distance or not (step S4); and accumulating and recording a tailgate operation degree for each vehicle when the determination is YES (steps S7, S9). The on-vehicle device determines that the other vehicle 3 is a tailgating operation vehicle when accumulated tailgating operation degrees satisfy a predetermined condition.SELECTED DRAWING: Figure 3

    【課題】他車両による危険運転を検知して、危険運転に起因する事故を未然に防止する。【解決手段】車載器は、前方又は後方の他車両との車間距離を測定し(ステップS3)、車間距離が所定距離以下か否かを判断し(ステップS4)、YESの場合、車両ごとにあおり運転度を累積・記録する(ステップS7、S9)。車載器は、累積されたあおり運転度が所定条件を満たすと、他車両3があおり運転車両であると判定する。【選択図】図3
