A vehicular data recording apparatus having a memory that records running data regarding a vehicle and a controller that determines whether the vehicle is in an abnormal state, and controls a recording of the running data by the memory based on whether the vehicle is determined to be in the abnormal state, wherein the controller determines whether a vehicle speed of the vehicle is equal to or less than a reference speed value, characterized in that the controller determines whether a magnitude of an acceleration of the vehicle is equal to or greater than a reference acceleration value; and determines whether the vehicle is in an abnormal state based on a result of the determinations regarding the acceleration and speed of the vehicle, wherein the controller determines that the vehicle is in the abnormal state if the controller determines that the vehicle speed is equal to or less than the reference speed value and the controller determines that the acceleration of the vehicle is equal to or greater than the reference acceleration value, wherein the controller determines whether a magnitude of a longitudinal acceleration of the vehicle is equal to or greater than a reference longitudinal acceleration value, and determines whether a magnitude of a lateral acceleration of the vehicle is equal to or greater than a reference lateral acceleration value; and the controller determines that the vehicle is in the abnormal state if the controller determines that the vehicle speed is equal to or less than the reference speed value and the controller determines that the magnitude of the longitudinal acceleration of the vehicle is equal to or greater than the reference longitudinal acceleration value, or if the controller determines that the vehicle speed is equal to or less than the reference speed value and the controller determines that the magnitude of the lateral acceleration of the vehicle is equal to or greater than the reference lateral acceleration value. the controller determines whether a vehicle speed of the vehicle is equal to or less than a reference speed value, characterized in that the controller determines whether a magnitude of an acceleration of the vehicle is equal to or greater than a reference acceleration value; and determines whether the vehicle is in an abnormal state based on a result of the determinations regarding the acceleration and speed of the vehicle, wherein the controller determines that the vehicle is in the abnormal state if the controller determines that the vehicle speed is equal to or less than the reference speed value and the controller determines that the acceleration of the vehicle is equal to or greater than the reference acceleration value, wherein the controller determines whether a magnitude of a longitudinal acceleration of the vehicle is equal to or greater than a reference longitudinal acceleration value, and determines whether a magnitude of a lateral acceleration of the vehicle is equal to or greater than a reference lateral acceleration value; and the controller determines that the vehicle is in the abnormal state if the controller determines that the vehicle speed is equal to or less than the reference speed value and the controller determines that the magnitude of the longitudinal acceleration of the vehicle is equal to or greater than the reference longitudinal acceleration value, or if the controller determines that the vehicle speed is equal to or less than the reference speed value and the controller determines that the magnitude of the lateral acceleration of the vehicle is equal to or greater than the reference lateral acceleration value.
