Which signal indicates 'GO Ahead'?

Which signal indicates 'GO Ahead'?

• A. ONE short blast 'STOP'
• B. TWO short blasts 'GO Ahead'
• C. ONE continuous blast 'EMERGENCY STOP'
• D. Three short blasts 'Back Up'

Answer: (B)

Understanding horn signal patterns is essential for coordinating movement with other units and personnel in the fire service. In this signaling system, two short blasts mean you are cleared to proceed—“Go Ahead.” The short-blast patterns are designed to be quickly recognized in loud, emergency environments: a single short blast means Stop, three short blasts means Back Up, and a continuous blast signals Emergency Stop. The two-short sequence is distinct and reliably heard, which is why it represents going ahead.
