An alertness level of a driver is determined, a periodic stimulus is provided to the driver based on that level, and the drivers periodic response to that stimulus is analysed to maintain the drivers alertness. The drivers alertness level may be determined using biometric parameters such as heart rate or blood pressure. In some embodiments the stimulus is provided only if the determined alertness level is below a threshold. The stimulus may be audio, visual or physical, and may vary as a function of the vehicles location, the time of day or earlier responses by the driver to earlier stimuli. The drivers response may be an audio or physical response. If an unfavourable response from the driver is detected, then the periodic response may be provided iteratively, or possibly a reduced power delivered to the vehicles drive train. A database of historical accidents may be used to warn the driver.
