The invention relates to a travel control apparatus for a vehicle. A passing is controlled by utilizing automatic driving technology that appropriately collects information about driving state of the back vehicle and/or parallel travelling vehicle in the passing lane on condition that non-passing is preferential or for example, lane-change for passing is selected and finally the vehicle return to the original lane on condition that non-passing of the front vehicle is preferential; and notifies the driver or automatically changes lanes to the original lane. The travel control apparatus for a vehicle detects a vehicle to be passed that is a target of passing and is in front of the vehicle equipped with the apparatus in the traveling lane thereof, detects a parallel traveling vehicle that is traveling in a lane that is adjacent to a lane to which the vehicle performs lane changing to pass the vehicle to be passed and is located on the opposite side of the lane which the vehicle to be passed is traveling, monitors the vehicle to be passed and the parallel traveling vehicle, and variably controls a passing maneuver with respect to the vehicle to be passed on the basis of a monitoring result.
