It is used to inform motorists of an upcoming traffic light, especially where visibility is limited or the signal is unexpected. The high-contrast design ensures visibility in varied lighting conditions.

Used on roads and highways to warn drivers of an upcoming traffic signal intersection, particularly where sight distance is restricted or where signals are newly installed. Matches user intent for understanding road signage, driver education, or traffic engineering resources.
