What does a signal by an authorized person indicating traffic approaching from behind typically look like?

• A. Pointing forward
• B. Waving both arms
• C. Raise one arm with fingers spread
• D. Hold up a hand with palm facing down

Answer: (B)

The correct answer reflects the common practice of signaling to indicate to drivers that they should be cautious of traffic approaching from behind. Waving both arms is a clear visual signal that indicates urgency and draws drivers' attention. This action serves as a warning to be alert and to take necessary precautions, especially in situations where back traffic may pose a hazard, such as during a stop or when preparing to make a turn. The other options do not convey the same level of urgency or clearly communicate the potential approaching danger from behind a vehicle. For instance, pointing forward could confuse drivers about the direction they should focus on, while raising one arm with fingers spread does not traditionally signal any specific type of warning in traffic management. Similarly, holding up a hand with the palm facing down is typically used to indicate stop or caution, but it does not effectively communicate the presence of traffic approaching from behind.
