What does the '비보호' sign signify?

The '비보호' sign indicates an unprotected left turn. This means that vehicles making a left turn at an intersection with this sign do not have a dedicated green signal or right-of-way against oncoming traffic. Therefore, drivers must yield to oncoming vehicles and pedestrians before making the turn, highlighting the need for heightened vigilance and caution.

In contrast, a protected left turn would allow vehicles to turn left while opposing traffic is stopped by a green arrow, signifying that the turn is safe and permitted without needing to yield. A no left turn sign explicitly prohibits any left turn, which is not what the '비보호' sign indicates. Lastly, while yielding to pedestrians is vital at intersections, it does not pertain specifically to the meaning of '비보호,' which focuses on the conditions surrounding left turns in particular.
