The invention provides an automobile capable of displaying low-speed driving by a tail red light. A control circuit of a tail red light (7) of the automobile is characterized in that a microcontroller (4) receives driving and safe parking information output by an automobile key main switch (2) by a driver or brake information output by a brake switch (6) and automobile speed information sent by an automobile speed acquisition unit (3), and the information is processed by the microcontroller (4) to form control information on the tail red light (7); the information is transmitted to an interval controller (5); the interval controller (5) is used for controlling flashing duration and interval duration of the tail red light (7); when the driver of a behind automobile sees that the tail red light of the front automobile flashes from the far place, the driver of the behind automobile can do speed-reduction avoidance and brake emergency treatment in advance so that the possibility of the rear-end collision is reduced.
