To make it possible to appropriately determine whether a driver is looking ahead carefully regardless of the state of a road.SOLUTION: A safe driving determination device 4 comprises an angular value calculation unit 421 for calculating an angular value indicating a driver's face direction angle with respect to a traveling direction, a determination unit 423 for determining whether the driver is looking ahead carefully based on whether an angular value during a predetermined determination period in the past is equal to or greater than a threshold, and a road state identification unit 422 for identifying a state of a road along which a vehicle S is travelling. The determination unit 423 determines a determination period based on the state of the road along which the vehicle S is travelling.SELECTED DRAWING: Figure 1

    【課題】道路の状態によらず、運転者の不注視状態であるか否かを適切に判定できるようにする。【解決手段】安全運転判定装置4は、進行方向に対する運転者の顔向き角度を示す角度値を算出する角度値算出部421と、過去の所定の判定期間内の角度値が閾値以上であるか否かに基づいて、運転者が前方不注視状態であるか否かを判定する判定部423と、車両Sが走行している道路の状態を特定する道路状態特定部422と、を有し、判定部423は、車両Sが走行している道路の状態に基づいて判定期間を決定する。【選択図】図1
