Which sign indicates that you must stop?

Answer: B — Stop sign

The sign that indicates you must come to a complete stop is the stop sign. This sign is universally recognized and features an octagonal shape with the word "STOP" prominently displayed in white letters on a red background. When you see a stop sign, it means that you must bring your vehicle to a full stop at the marked stop line, crosswalk, or intersection before proceeding, ensuring that you yield to any pedestrians or oncoming traffic. Each type of sign serves a different purpose on the road. A yield sign, for instance, instructs drivers to slow down and yield to oncoming traffic but does not require a complete stop unless necessary. Warning signs alert drivers to potential hazards ahead, such as curves or pedestrians in the area, without instructing them to stop. Speed limit signs indicate the maximum permissible speed for vehicles but do not require any stopping. Understanding the function of these various signs is crucial for safe driving and compliance with traffic regulations.
