A turn control system for a work vehicle includes a controller having a memory and a processor. The controller is configured to receive a first signal from a turn signal input assembly of the work vehicle indicative of a turn indication. The controller is also configured to output a second signal indicative of activation of a turn signal indication assembly based on the turn indication while in a manual control mode. In addition, the controller is configured to output a third signal to a movement control system indicative of instructions to control a turn direction of the work vehicle at an end of a guidance swath based on the turn indication while in an automatic control mode.
