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 bandpass filter 18 to generate filtered horizontal components of acceleration and a communication device 20 for transmitting crash alert information, wherein the data processor 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 if the threshold value is exceeded. The system is adapted to be retro-fitted to a vehicle. The bandpass filter may be a FIR or IIR filter. The threshold value may be set at 0.05 to 30g2. A method of low-impact crash detection is also provided, the method including a crash scoring method.
