The invention relates to a method for operating an electrically driven motor vehicle and a motor vehicle. The invention relates to a method for operating an electrically driven motor vehicle having ahigh-voltage system, in which, in the event of a fault in the high-voltage system, the fault is evaluated in regard to a risk, and a first risk level corresponding to the risk is assigned to the faultas a result of the evaluation, wherein a current driving situation is evaluated with regard to a hazard occurring as a result of switching off the high-voltage system, and a second hazard level corresponding to the hazard is assigned to the current driving situation as a result of the evaluation; the first hazard level and the second hazard level are compared with each other with respect to the magnitude of the respective hazard assigned to the hazard levels; and the high-voltage system is shut off if the danger assigned to the first danger level is greater than the second danger level, and otherwise the high-voltage
