A collision determining apparatus for a vehicle includes a vibration detection device that detects a high-frequency vibration of an audio band generated in a vehicle and a low-frequency vibration of the audio band which is lower than the high-frequency vibration; and a collision determining device that determines whether or not a collision requiring an activation of an occupant protection apparatus of the vehicle has occurred based on the detection result of the high-frequency vibration and the low-frequency vibration.
