A driving support apparatus includes an output unit installed in a steering wheel that outputs steer information about a rotation operation of the steering wheel to the driver through the output unit. By providing the driver with steer information from the output unit in the steering wheel, the driver may recognize the contents of the output of the steer information. Further, since the steer information has a high priority for the driver due to its direct relevance to movement and a travel direction of the vehicle, providing such high priority steer information in an easily-recognizable manner improves driver awareness or readiness to recognize lower-priority information. Thus, information overload by the driver caused by information from various driving support techniques is prevented.
