A driver drowsiness detection and alerting system has a plurality of marks in a ring configuration around an exterior cylindrical surface of a vehicle's steering wheel column assembly. An optical sensor assembly is located near the plurality of marks for detecting movement of the marks. The optical sensor assembly is connected to a device for alerting the driver if the steering wheel does not move for a prescribed time period while the motor vehicle is moving. The optical sensor assembly has an optical detector and a light emitter adjacent to each other. Additionally, the present invention relates to a kit of parts for such driver drowsiness detection and alerting system.
