The invention discloses a detection barrier gate with a vehicle weight limiting function, and relates to the technical field of barrier gates. The barrier gate comprises a weight detection device, a height limiting device, a disinfection device, a first barrier plate, a deceleration strip, a second interception device and a barrier gate device. In order to solve the problems of bridge collapse and casualties caused by overweight and superelevation of existing vehicles, the weight detection device, the height limiting device, the first barrier plate and the barrier gate device are arranged, passing vehicles are detected one by one through the weight detection device, when the vehicles are overweight, the first barrier plate pops up from the ground, a voice prompt is given out, overweight vehicles are prohibited from getting on the bridge, and the safety of the bridge is guaranteed; and the deceleration strip and the second interception device are arranged, when the vehicle does not hear dissuasion and hard rushing, the second intercepting device pops up from the ground, an intercepting blade punctures vehicle tires, and the overweight vehicle is forced to stop.
