Abstract: A method and system for impaired driving detection, monitoring and accident prevention with driving habits. An impairment test method is provided with an impairment test determining in real-time whether a driver of vehicle is impaired (e.g., has used drugs, alcohol, is distracted, talking, texting, eating, etc. or is drowsy, etc.). The impairment test determines plural assigned probability impairment values over a pre-determined time interval to compare a frequency of received plural event signals from a passenger compartment of the vehicle and from an environment detected outside the vehicle and external to the vehicle for one or more of the plural driver performance actions completed by a driver of a vehicle to those previously stored in a unique driver profile for the driver to determine with a statistical probability whether the driver operating the vehicle may be impaired based on the unique behavior patterns for the driver of the vehicle stored in the unique driver profile.
