Angle requirements for setting traffic sign poles
The traffic sign pole should be installed so that the sign surface is perpendicular to the driving direction, and its horizontal or pitch angle should be adjusted depending on the actual situation;
The installation of the sign should minimize the glare of the sign facing the driver; the installation angle of the sign should be adjusted according to the flat and vertical curves of the road at the set location.
Roadside signs should be as perpendicular to the middle line of the road as possible or at some angle. Among them, the prohibition and indication signs are 0°~45°, the direction and warning signs are 0°~10°, and the attached signs above the gantry, cantilever, and roadway should be perpendicular to the road driving direction, and the panels should be inclined 0°~15°.
