This paper explains the nonstandard safety technology which assists drivers to enhance drive safety when the driver is physiologically impaired, for example, drunk, fatigued, irritable, asleep, etc. When a driver operates a vehicle with some actions which may not result in an accident immediately but may reveal that the driver is drunk, fatigued, or asleep, the non-standard safety enhancement system makes a decision from the actions to determine whether the driver is physiologically impaired based on the available information of vehicle, road, and others before the driver causes an accident.
