What do the "Wrong Way" and "Do Not Enter" signs indicate?

The "Wrong Way" and "Do Not Enter" signs are critical indicators for drivers, primarily used to prevent them from accidentally entering lanes or roadways where they could pose a danger to themselves and others. These signs specifically alert drivers that they are approaching a restricted area, such as the wrong side of a one-way street or an entrance ramp that leads onto a highway in the opposite direction.

By indicating that a driver should not proceed past these signs, the message is clear: entering these areas is not only prohibited but also dangerous. Such signage is vital for maintaining safe driving conditions and preventing head-on collisions, which can have severe consequences. Understanding the purpose of these signs is essential for all drivers, especially those learning the rules of the road. Therefore, recognizing that these signs indicate a one-way street or expressway ramp that should not be entered is crucial for safe navigation and adherence to traffic laws.
