An electrically powered vehicle including an electric motor connected to drive a wheel of the vehicle. The electric motor receives a supply of electric current from a power source; a power electronics device and superordinated controller regulate the current supply based upon signals received from a driver or operator of the vehicle. A sensor for sensing data indicative of an accident or impending accident is connected to the superordinated controller in which the sensed data is compared to predetermined limit values to determine if an accident situation exists. Upon determining that an accident situation exists, the superordinated controller activates a circuit breaker to disconnect the electric power supply and thereby interrupt the supply of electric current to the electric motor.
