Traffic road sign and plate identification

Quick answer：

Traffic road signs and plates are visual symbols used to communicate rules, regulations, and directions to road users. They are crucial for ensuring safety and order on the roads. These signs can be regulatory (e.g., speed limits, stop signs), warning (e.g., curves ahead, school zones), or informational (e.g., road names, directions). International standards, such as those set by the Vienna Convention on Road Signs and Signals, exist to ensure consistency across countries.
