What is the purpose of warning signs on the road?

Warning signs on the road are specifically designed to alert drivers to potential hazards or changes in road conditions ahead. These signs play a critical role in enhancing safety by providing visual indications of situations that could pose a risk, such as sharp turns, merging lanes, pedestrian crossings, or hazardous weather conditions.

By signaling potential dangers or adjustments in the driving environment, warning signs give drivers the necessary information to adjust their speed and be cautious, thereby preventing accidents. Understanding these signs helps enhance situational awareness and promotes safe driving behavior.

The other options refer to functions of different types of road signs. For instance, speed limit signs are focused on regulating how fast a driver can legally go, direction signs offer navigational assistance, and construction signs inform about active roadwork areas. Each has its unique purpose, distinct from that of warning signs, which prioritize alerting drivers to immediate dangers.
