There is provided a low-impact crash detection system for a vehicle (10) comprising an accelerometer device (14) from which horizontal components of acceleration are derived, a data processor (16) comprising a FIR bandpass filter (18) to generate filtered horizontal components of acceleration and a communication device (20) for transmitting crash alert information, wherein the data processor (16) is configured to generate an impact energy signal from the filtered horizontal acceleration components, to compare the impact energy signal with a threshold value to determine whether a low-impact crash has taken place, and to generate a crash alert for transmission by the communication device (20) if the threshold value is exceeded. The system is adapted to be retro-fitted to a vehicle. A method of low-impact crash detection is also provided, the method including a crash scoring method.
