ABSTRACT:
A graduated optic tape is mounted on a steering wheel component and is read by an optical sensor. The sensor is electrically connected to a first and second timer and a buzzer for alerting a driver when the steering wheel in a moving vehicle is not turned for five to ten seconds. A DC power supply provides electrical energy. The system is connected to the vehicle brake light so that the buzzer does not sound when the brake is engaged.
