A slip control device for a vehicle provided with an internal combustion engine, wherein an engine output torque is controlled independently of a depression of the accelerator pedal so that slip at the driving wheels of the vehicle is controlled. A stand-by means is provided and operates, upon a prediction of an occurrence of slip at the vehicle wheels, to close the throttle valve to a stand-by degree of opening thereof before the occurrence of the slip. The stand-by degree of opening of the throttle valve is controlled in accordance with an engine torque of the engine when the occurrence of slip is predicted. Thus the occurrence of slip is effectively prevented and a good acceleration performance obtained.
