What is the main purpose of traffic signs?

The main purpose of traffic signs is to communicate important information about road conditions, rules, and warnings to drivers. These signs are designed to ensure the safety and efficiency of roadway use by conveying crucial messages such as speed limits, directions, navigation assistance, and cautionary alerts about hazards. This flow of information helps drivers make informed decisions, adhere to traffic laws, and navigate roadways safely.

The other options, while they may have some relevance in specific contexts, do not accurately represent the primary role of traffic signs. For instance, entertaining drivers is not the intent behind traffic signage; its focus is strictly on safety and regulation. Although promoting local businesses or indicating the fastest routes can sometimes occur through specific signage, they are not the primary function of standard traffic signs. The central goal remains clear communication of vital traffic-related information.
