What does an eight-sided octagonal traffic sign always indicate on Utah roads?
The answer
Answer: B. An octagonal (eight-sided) sign always indicates a mandatory complete stop. Motorists approaching a stop sign must bring their vehicle to a complete stop before the stop line, crosswalk, or intersection boundary, and yield right-of-way to pedestrians and oncoming traffic before proceeding safely. The handbook says to stop smoothly behind the stop line, crosswalk or stop sign, whichever comes first, without skidding.
