What does a sign indicating the beginning of a 2-way street look like?

Answer: C — It has two arrows that may be yellow

The sign indicating the beginning of a 2-way street is characterized by two arrows that may be in yellow, which serves as a visual cue to drivers that they should prepare for oncoming traffic from the opposite direction. This is crucial for ensuring safety as it alerts drivers to the potential for vehicles traveling in both directions, which may not be an expectation when approaching a street. The use of two arrows signifies movement in both directions, while the possibility of yellow coloring serves to heighten visibility, especially in various weather conditions or low-light situations. Yellow is often associated with caution, further emphasizing the need for awareness when entering a roadway that allows for two-way traffic. Contextually, this sign is important in urban or suburban environments where streets may shift from one-way to two-way, so that drivers are adequately informed of the change and can adjust their driving habits accordingly.
