What type of sign alerts drivers to unexpected road conditions?

Warning signs are crucial for alerting drivers to unexpected road conditions. These signs are typically yellow or orange, utilizing symbols or messages to convey potential hazards ahead. For instance, they may indicate sharp turns, slippery roads, construction zones, or wildlife crossing areas, allowing drivers to prepare and react accordingly.

The purpose of warning signs is to improve safety by providing advanced notice of conditions that might not be immediately visible, thus helping to prevent accidents. Each warning sign serves a specific purpose, using recognizable symbols that convey urgent safety information.

Service signs generally provide information about amenities or services available along the roadway, regulatory signs communicate laws and regulations that must be followed, and guide signs help with navigation by indicating directions or distances. While these types of signs provide valuable information to drivers, they do not specifically alert them to unexpected road conditions in the same way that warning signs do.
