Philadelphia Drivers License Practice Test

What must a driver do when they encounter a stop sign at an intersection?

1. Slow down and proceed if clear.

2. Come to a complete stop.

3. Stop briefly and then continue if safe.

4. Only stop if other vehicles are present.

The correct answer is: Come to a complete stop.

When encountering a stop sign at an intersection, the correct action for a driver is to come to a complete stop. This requirement is crucial for ensuring the safety of all road users. A complete stop allows the driver to adequately assess the situation at the intersection, ensuring they have the opportunity to observe cross traffic, pedestrians, and any potential hazards before proceeding. This action is important as it establishes a clear and consistent traffic rule that all drivers must follow, which helps prevent collisions and maintains the flow of traffic. By stopping fully, drivers can make informed decisions about when it is safe to proceed, thus enhancing overall road safety for everyone involved. Other choices suggest less stringent measures, such as slowing down or stopping briefly, which could lead to misunderstandings about right-of-way and could compromise safety if a driver misjudges the presence of other vehicles or pedestrians.
