What is the main purpose of road signs?

The main purpose of road signs is to provide information, warnings, and instructions to drivers. This is essential for safety and efficiency on the road. Road signs are designed to alert drivers to important information, such as caution signs that warn about potential hazards, regulatory signs that inform drivers of rules, and informational signs that guide them to their destinations.

By fulfilling these essential functions, road signs help to ensure that drivers can navigate safely and effectively while adhering to traffic laws. This clarity in communication is vital for reducing accidents and improving overall road safety. The other options do not accurately capture the multifunctional role that road signs play in fostering safe driving conditions.
