What is the correct action to take at a stop sign?

The correct action to take at a stop sign is to come to a complete stop. This is a fundamental traffic rule designed to ensure the safety of all road users. By coming to a complete halt, you allow yourself the opportunity to check for any oncoming vehicles, pedestrians, or cyclists that may have the right of way before proceeding.

The requirement to stop enables drivers to assess their surroundings thoroughly, thereby reducing the risk of collisions. It also promotes defensive driving, as you are not just relying on your vehicle's speed but are actively scanning the intersection for potential hazards. Following this rule contributes to smoother traffic flow and enhances road safety for everyone, including those who may not be as visible.

Other options suggest actions that do not fully comply with the rules governing stop signs. For instance, simply slowing down does not provide the same level of safety and may lead to misunderstanding other drivers' actions regarding their right-of-way. Similarly, yielding to vehicles only or always turning in a specific direction does not address the critical need to check the entire intersection and stop as required. Therefore, coming to a complete stop is the correct and most responsible response at a stop sign.
