The invention discloses a car following safety distance alarm system which comprises a car distance measurement module, a car speed measurement module, a temperature measurement module, a humidity measurement module, an MCU processing module, a display module and an alarm module. The signal output end of the car distance measurement module, the signal output end of the car speed measurement module, the signal output end of the temperature measurement module and the signal output end of the humidity measurement module are correspondingly connected with the signal input end of the MCU processing module. The signal output end of the MCU processing module is correspondingly connected with the signal input end of the display module and the signal input end of the alarm module. The safety-hold distance can be calculated according to different car speeds, different relative speeds, different roads and different outside conditions (such as weather and humidity) of the two following cars, drivers are reminded, and therefore traffic accidents of tailgating and lateral colliding can be reduced. For the defects in the background technology, the car following safety distance alarm system which is simple in structure, high in flexibility, high in precision and low in false alarm rate is provided.
