What should you do when you see a stop sign?

Answer: B — Come to a complete stop

When you see a stop sign, it is required to come to a complete stop at the designated stop line or before entering the crosswalk or intersection. This rule is in place to ensure the safety of all road users and to facilitate the orderly flow of traffic. Stopping allows you to properly assess the area for any vehicles, pedestrians, or cyclists that may be crossing or entering the intersection, which is crucial to preventing accidents. This action illustrates the principle of yielding the right of way to others and making informed decisions based on the current traffic conditions. Other options suggest behaviors that do not align with traffic laws regarding stop signs, which could lead to dangerous situations or potential accidents. For instance, slowing down without stopping or proceeding without a full stop could deny the right of way to vehicles or pedestrians that may not be immediately visible, resulting in a higher risk of collisions.
