What does the wrong way sign indicate to a driver?

The wrong way sign serves as a critical alert for drivers, indicating that they are traveling in the opposite direction on a one-way street. This sign is placed to prevent accidents by informing drivers that their current path is unsafe and they are likely to encounter oncoming traffic. Understanding this warning is essential for maintaining safety on roadways.

While the other options may involve aspects of driving, they do not directly pertain to the specific function of the wrong way sign. For instance, being on a two-way street does not necessarily indicate a violation of direction, and a driver may not need to turn around immediately unless they are indeed going the wrong way. Approaching a pedestrian crossing is also unrelated to the implications of the wrong way sign. Thus, recognizing the correct meaning of the sign is vital for ensuring safe navigation.
