At which of the following must you always stop?

You must always stop at stop signs because they represent a clear and absolute requirement for drivers to come to a complete halt at the designated intersection. The purpose of stop signs is to ensure the safety of all road users by controlling traffic flow and allowing drivers sufficient time to assess the intersection for other vehicles, pedestrians, or any potential hazards.

When approaching a stop sign, it is critical for drivers to reduce their speed and stop completely before proceeding, ensuring they observe the right-of-way rules. This prevents accidents and allows for a safe merging of traffic in situations where multiple roads converge.

In contrast, yield signs instruct drivers to slow down and yield the right-of-way to oncoming traffic without mandating a complete stop in every case. Green lights indicate that vehicles can proceed but require drivers to be cautious of any potential hazards. Roundabouts have specific traffic flow directions that do not necessarily require a full stop, but instead rely on yielding as vehicles navigate the intersection.
