What is the purpose of warning signs along roadways?

The purpose of warning signs along roadways is to indicate potentially hazardous conditions that drivers may encounter. These signs are designed to alert drivers to situations that require increased caution, such as sharp turns, pedestrian crossings, or changes in road conditions. By using distinct colors and symbols, warning signs effectively communicate important information that helps ensure the safety of all road users.

While other types of signs serve different purposes—like traffic signals regulating traffic flow, construction signs detailing work zones, and directional signs providing information on routes—warning signs specifically focus on alerting drivers to immediate dangers or changes in road conditions. This proactive approach plays a crucial role in accident prevention and enhancing overall roadway safety.
