The invention discloses a highway accident early warning and rear vehicle emergency risk avoiding guiding system which comprises a vehicle-mounted early warning guiding system and a roadside emergency risk avoiding guiding system. The vehicle-mounted early warning guide system comprises a detection device, a microprocessor, a LoRa communication module and an acousto-optic device, the detection device is connected with the microprocessor, and vehicle speed information is transmitted to the microprocessor when the detection device responds; the micro-processor is connected with the LoRa communication module and the acousto-optic device, and when the vehicle is judged to be abnormal, the micro-processor can send current vehicle speed abnormity or accident information to the nearest roadside emergency risk avoiding guiding system through the LoRa communication module; the roadside emergency risk avoiding guiding system comprises a microprocessor, a LoRa communication module and an acousto-optic device, and the microprocessor is connected with the LoRa communication module and the acousto-optic device. According to the invention, visualization of road condition information is realized, so that a driver of a rear coming vehicle can timely and accurately know the change information of the road condition in front, and the passing efficiency of the highway is greatly improved.
