On a safety walker that has two handles situated for grasping by the user while pushing or step-wise advancing the walker, a sensor is situated on each handle at a position where the user grasps the handles in use, for sensing hand proximity or pressure on each handle. A transmitter is associated with each sensor. A signal generator is responsive to the transmitters, for producing a warning signal to the user, when the user has only one hand on the handle. Thus, at least one signal generator is responsive to the transmitters, for producing a warning signal to the user when the sensor on one handle senses a hand and the sensor on the other handle does not sense a hand on the other handle. The system provides a warning before a dangerous tilt or fall is imminent.
