The steering control leading apparatus includes: a coordinate controller that analyzes images obtained by photographing the landmark installed on a road by a photographing apparatus installed in a car to generate current coordinate data and current driving lane data of a car; a lane controller that compares the current driving lane data or the current coordinate data received from targeted coordinate data and a coordinate controller to generate determined result data determining whether the car is normally driven; and a display unit that displays the current coordinate data, and the targeted coordinate data, or the data indicating whether the car is normally driven
