Description

The present invention takes up the field of traffic control technology, and specifically is a traffic control device for limiting vehicle altitude under the street of a road bridge.

Nowadays, as the transportation industry develops, the amount of trucks carried increases, and when some overpriced vehicles pass under the streets of road bridges, drivers try to forcefully pass with the feeling of wanting a jerk. As a result, the vehicle may get caught under the street of the bridge or the arch of the bridge may be broken, which will have a terrible impact on the safety of road traffic. As a solution, we generally install a horizontal bar of a certain altitude and add letters, but in the case of a malicious driver, it is possible to go under the street of the bridge without looking after it and the arch will be deformed. Anyway, depending on the situation, the arch may be broken, which greatly increases the maintenance cost.
