A driving analysis device comprises: a communicator configured to acquire yaw rates of vehicles driven by drivers and vehicle speeds corresponding to the angular velocities, and accident log information on whether or not the drivers each have accident logs; and a controller configured to analyze the driving behaviors of the steering operation of the plurality of drivers on the basis of the angular velocities and the vehicle speeds, and the accident log information. The controller categorizes the angular velocities into a first group having accident logs and a second group having no accident log, and determines at least one of a first reference value for detection of the abrupt steering operation or a second reference value for detection of the unsteady steering operation in accordance with an angular velocity at a boundary between the first group and the second group, for each of various vehicle speeds.
