Among them, the road traffic sign is a direct carrier for such legal provisions to interact with people. Whether the setting of road traffic signs is reasonable or not directly affects whether the roads are unobstructed, whether there are management loopholes, and even a wrong signage guide can lead to serious traffic accidents.
In real life, road traffic signs are usually composed of graphic symbols and corresponding numbers and characters, which clearly and accurately give people specific instructions to achieve a good and orderly promotion of social management order, and to ensure that people's daily travel becomes safer and convenient.
