What action must drivers take when they encounter a stop sign?

When drivers encounter a stop sign, the action they must take is to stop and proceed only when it is safe. This requirement ensures that the driver comes to a complete stop at the designated stop line or intersection before continuing on their way. The purpose of the stop sign is to regulate traffic flow and enhance safety, particularly at intersections where visibility may be limited or where competing traffic has the right of way.

By stopping, drivers can observe the intersection for any oncoming vehicles, pedestrians, or other hazards, allowing them to make informed decisions about when it is safe to proceed. This not only promotes the safety of the driver but also of others on the road, including cyclists and pedestrians.

The choices that involve bypassing the stop sign without a complete stop or only looking around instead of halting can lead to dangerous situations. Following the requirement to stop first is crucial for maintaining appropriate traffic control and ensuring overall road safety.
