What is the primary purpose of traffic signs?

The primary purpose of traffic signs is to provide important information and ensure road safety. Traffic signs are crucial for guiding drivers, informing them of rules and regulations, indicating hazards, and directing traffic flow. They create a safer driving environment by clearly communicating actions that drivers must take or the conditions they can expect on the road. For instance, stop signs instruct drivers to halt, yield signs indicate the need to give way to other traffic, and warning signs alert drivers to potential dangers ahead.

Other options do not align with the fundamental role of traffic signs. While law enforcement may be influenced by these signs, their main function does not center around regulating law enforcement activities. Similarly, promoting tourism or displaying advertisements are secondary uses that do not pertain to the essential safety and information roles that traffic signs serve on the road. The effectiveness of these signs heavily relies on their clarity and visibility, which directly contribute to accident prevention and overall road safety.
