Techniques are described for managing redundant steering system for a vehicle. A method includes sending a first control command that instructs a first motor coupled to a steering wheel in a steering system to steer a vehicle, receiving, after sending the first control command, a speed of the vehicle, a yaw rate of the vehicle, and a steering position of the steering wheel, determining, based at least on the speed and the yaw rate, an expected range of steering angles that describes values within which the first motor is expected to steer the vehicle based on the first control command, and upon determining that the steering position of a steering wheel is outside the expected range of steering angles, sending a second control command that instructs a second motor coupled to the steering wheel in the steering system to steer the vehicle. Start Operating a first steering motor of a redundant steering system to control or steer a vehicle Receiving speed, yaw rate and current steering wheel angle/ position of the vehicle Determining a range of steering angles No Is the current steering wheel angle/position outside the range of steering angles? Yes Activating and operating a second motor of the redundant steering system to control the vehicle
