What does an eight-sided octagonal traffic sign always indicate on Massachusetts roadways?
The answer
Answer: A. An octagonal (eight-sided) sign always means STOP under Massachusetts traffic law. Drivers must bring their vehicle to a complete halt before any painted stop line, crosswalk, or intersection boundary, yield the right-of-way to crossing pedestrians and approaching traffic, and proceed only when the way is completely clear.
