A car connected to at least one trailer and backward motion control method are provided. The car includes a driving part controlling a velocity and a direction of the car, a backward-motion control terminal outputting a first backward-motion control signal corresponding to a backward velocity and a backward direction of the last trailer according to a user's operation, a control signal converter converting the first backward-motion control signal to a second backward-motion control signal which corresponds to a backward velocity and a backward direction of the car and makes the last trailer move backward as the backward velocity and the backward direction corresponding to the first backward-motion control signal, and a backward-motion controller controlling the driving part on the basis of the second backward-motion control signal so that the last trailer moves backward by the backward velocity and the backward direction corresponding to the first backward-motion controlling signal.
