In which situation are you required to make a complete stop?

Answer: B — At a stop sign

Making a complete stop at a stop sign is a fundamental rule of the road and is crucial for ensuring safety at intersections. When approaching a stop sign, drivers are required to come to a full stop before the stop line, crosswalk, or intersection, depending on the layout of the road. This action allows the driver to check for oncoming traffic, pedestrians, and any other hazards before proceeding. By adhering to this rule, drivers can prevent accidents and ensure a smoother flow of traffic as all road users are respected. The legal obligation to stop fully ensures that drivers take the time to assess their surroundings adequately before making any further maneuvers.
