A drive control apparatus to be applied to an electric vehicle includes a controller. The controller is configured to limit a change rate of a torque to be outputted from an electric motor of the electric vehicle on the basis of a first limit mode in a case where the torque is less than a threshold torque, in a period of a first traveling state in which the electric vehicle travels on an uphill road where a level of likelihood of an occurrence of a slip is estimated to be equal to or greater than a threshold, and configured to limit the change rate of the torque on the basis of a second limit mode that is more flexible than the first limit mode in a case where the torque is equal to or greater than the threshold torque in the period of the first traveling state.
