In recent years, with urbanization and economic development, traffic flow has increased rapidly, and road traffic safety issues have become increasingly prominent. Traffic signs are an indispensable part of daily driving, playing a guiding, warning, and instructive role on the road. The shape and size of traffic signs are very important standards. Below is a detailed introduction to the shapes and sizes of traffic signs.
Traffic signs come in three shapes: circular, triangular, and rectangular.
1. Circular Signs
Circular signs are traffic signs based on a circular shape. Circular signs are commonly used for directional and informational signs, such as traffic instruction signs, information signs, prohibition signs, and directional signs.
Circular signs come in three diameters: small circular signs, standard circular signs, and large circular signs.
- Small circular signs: Diameter less than 400 mm.
- Standard circular signs: Diameter 600 mm.
- Large circular signs: Diameter 900 mm.
2. Triangular Signs
Triangular signs are traffic signs based on a triangular shape. Triangular signs are commonly used for warning and emergency purposes.
Triangular signs come in two sizes: small and large.
- Small triangular signs: base length less than 500 mm.
- Large triangular signs: base length greater than 500 mm.
3. Rectangular Signs
Rectangular signs are traffic signs based on a rectangular shape. They are commonly used for directional signs and speed limit signs.
Rectangular signs come in four sizes: small, standard, large, and extra-large.
- Small rectangular signs: shorter side less than 300 mm, longer side less than 600 mm.
- Standard rectangular signs: longer side 600 mm, shorter side 450 mm.
- Large rectangular signs: longer side 900 mm, shorter side 600 mm.
- Extra-large rectangular signs: the longer side is greater than 900 mm and the shorter side is greater than 600 mm.
