The gantry traffic sign pole is installed on the gantry, and the height of the lower edge of the sign above the ground should be greater than the clearance height specified for the road. Attached traffic sign post: The sign is attached and installed on the overpass and nearby structures, and is divided into two types: attached on the roadway and attached on the road according to the position of the attached layout.

　　The setting (adjustment) of road traffic signs should be completed before the completion and opening of new (renovated, expanded) roads, and the signs related to these new (renovated, expanded) roads in the road network should also be adjusted and improved accordingly. When there are changes in road traffic conditions, the setting of relevant signs should be adjusted in a timely manner. Highway number and city road name signs should be used as much as possible to enable road users to understand their route and location. The logo should be regularly cleaned and maintained to maintain sufficient reflectivity and ensure visual recognition.

A speed limit sign, also known as a speed limit traffic sign, indicates that on a road where the speed limit sign or another speed limit sign with a different value is removed from the front, the speed of motor vehicles (in km/h for enterprises) is prohibited from exceeding the indicated value. The speed limit traffic sign is set at the starting point of the road where the speed of vehicles must be limited, and its speed limit value should not be less than 20km/h. The manufacturer of Feiyao traffic signs provides a report based on 10 years of experience in exchanging specifications and models of speed limit traffic signs: in other words, as driving speeds increase, the specifications of speed limit traffic signs also increase. Additionally, the reflective film regulations applied to the surface of speed limit signs vary depending on the level of road surface. Generally, the reflective film level regulations applied to roads with faster driving speeds are higher. For example, when indicating direction on highways, the reflective film used is usually dominated by Class V or Class IV. Depending on the road surface, there are five key types of reflective film that can be used to make speed limit traffic signs: Class I, Class II, Class III, Class IV, and Class V.
