The device for preventing sudden starting of an automobile includes a starting motor, a power source, a starting switch, a solenoid switch, first and second connecting terminals and an actuator. The starting switch is electrically coupled to the power source. The solenoid switch is mechanically coupled to the starting motor and electrically coupled to the starting switch. The first and second connecting terminals are spaced apart from one another. The first connecting terminal is electrically coupled to the starting motor and the second electrical terminal is electrically coupled to the starting switch. The actuator is disposed between the connecting terminals for effecting an electrical connection between the connecting terminals to apply operating power to the starting motor when both the starting switch is in an ON position and the actuator is supplied with an operating pressure generated by depression of a brake pedal.
