To start traffic moving you should use proper arm movement and

• A. A circular hand motion without whistle
• B. A wave and a nod
• C. Two short whistle blasts
• D. A single long whistle blast

Answer: (C)

Starting traffic safely relies on a clear combination of a visible hand cue and a recognizable whistle pattern. Two short whistle blasts are the standard signal to indicate that traffic may begin moving. This pattern is distinct and easily understood by drivers and pedestrians, even in a noisy environment, and it directly communicates permission to proceed. The arm movement draws attention visually, while the two quick whistles reinforce the instruction audibly. Other signals—like circular hand motions without a whistle, a wave and a nod, or a single long whistle blast—can be ambiguous, easily misinterpreted, or associated with other instructions, which can lead to hesitation or unsafe gaps in the crosswalk.
