The device has a first detecting device for detecting a running speed of the vehicle, a second detecting device for detecting a specific point of time during a starting period of the vehicle, and a judging device for comparing the running speed of the vehicle detected by the first detecting device, with a predetermined threshold value when the specific point of time is detected by the second detecting device.
