Which signal indicates a Traffic Obstruction due to a Streetcar?

• A. 82
• B. 83
• C. 84S
• D. 85

Answer: (A)

A signal set aside for Traffic Obstruction caused by a streetcar is the one that directly communicates that a streetcar is blocking the roadway. This distinction matters because it tells you to treat the scene as a transit-related blockage and to coordinate with streetcar operations, protect the area, and direct traffic around the tracks safely. The other obstruction signals describe different situations (such as non-streetcar blockages or varying incident types) and do not indicate a streetcar-specific blockage, so they wouldn't convey the exact action needed. When you encounter the streetcar obstruction signal, prioritize scene safety, control traffic around the tracks, and contact transit control or streetcar personnel to clear the obstruction promptly.
