A starting ramp assembly is intended for use with a wheeled vehicle for enhancing the starting ablility of the vehicle and for moving with the vehicle in a forward direction after the vehicle is clear thereof. The assembly includes a wedge-shaped ramp which has a generally rectangular ground-contacting base, including a frame which has plural, box-like regions formed therein. Plural base pads are mounted to the frame and are spring-biased to a position where the pads extend below the level of the base and provide a skid surface when the vehicle is clear of the ramp, the pads being shiftable upwards relative to the frame when the vehicle is on the ramp, providing a slip-resistant contact between the frame and the ground. The ramp includes an inclined, vehicle-support surface which extends upwards from one end of the base and an upright member extending between the other end of the base and vehicle-support surface. A length of chain is connected to the other end of the ramp and is attachable to the vehicle. A coil spring extends between a side of the ramp and the chain and provides direction orienting mechanism which is operable to direct the chain along a side of the ramp as the vehicle clears the ramp, causing end-for-end rotation of the ramp.
