Abstract: A method and an apparatus for preventing and, at an early stage, removing wheel spin and a consequent lateral skidding of vehicles while constantly supervising and upon need reducing the momentary torque of the motor by blocking the fuel supply to one or more cylinders of the motor without influencing the optimum fuel/air relationship, whereby the skidding of a vehicle is observed as known per se and the fuel supply to one or more cylinders of the motor is/are completely inhibited in case an unacceptably great skidding is observed, by defining in a controlling means (13) a constant chain of combustions including a predetermined number of successive part-combustions of the motor, and by inhibiting, in case of an actual skidding, first one and then a successively increasing number of part-combustions of the chain of combustion, corresponding to the combustion of some specificly determined cylinders of the motor, said inhibiting being proceeded until the skidding has been brought to cease or has been reduced to
