When an ultrahigh vehicle passes through the device, the ultrahigh part of the vehicle firstly acts on the swing plates 13 in the two alarm mechanisms, so that the swing plates 13 swing around the corresponding rotating shafts 10 towards the driving direction of the vehicle; the swinging plate 13 drives the sensor A14 arranged on the lower surface of the swinging plate to meet and sense the sensor B15 arranged on the upper end surface of the supporting cylinder 8; the sensor B15 controls the loudspeaker 11 installed on the top of the rotating shaft 10 to send out the alarm sound of 'super high, forbid stopping at the position, and forward completely passing through the device for backing a car'; when the side of the vehicle superelevation part contacts the end of the swing plate 13, the swing plate 13 swings around the rotating shaft 10 to the limit position, and the front wheels of the vehicle start to roll the first speed reduction plate 26.
