Which type of traffic sign serves as a warning to indicate a change in road conditions?

Warning signs play a crucial role in road safety as they are specifically designed to alert drivers to potential hazards or changes in road conditions ahead. These signs often indicate situations such as merging traffic, curves in the road, or changes in speed limits, all of which require drivers to adjust their behavior to maintain safety.

Unlike regulatory signs, which enforce laws and must be followed strictly, warning signs serve as alerts, allowing drivers to prepare for upcoming changes or dangerous conditions. Guide signs, on the other hand, provide information about routes, distances, and locations but do not indicate potential hazards. Information signs typically convey general information rather than warnings about road conditions.

Thus, the identification of warning signs is essential for safe driving, as these signs are vital in preventing accidents by informing drivers of changes they need to anticipate and react to on the road.
