A limp home mode drive method and system for a hybrid vehicle are provided. The method includes prohibiting an operation of an overdrive brake that is included in a transmission for the hybrid vehicle and is driven by an electric oil pump when the hybrid vehicle is being driven and the electric oil pump is not operated. A speed of the hybrid vehicle is then limited based on a heat value of a rotation driver included in the transmission and a torque of a drive motor driving the transmission is limited based on a temperature of the drive motor. A mechanical oil pump included in the hybrid vehicle is operated to enable limp home driving of the hybrid vehicle.
