What does a 'stop' sign require drivers to do?

Answer: B — Come to a complete stop at the intersection

A 'stop' sign requires drivers to come to a complete stop at the intersection. This traffic control device is designed to ensure that vehicles halt fully before proceeding, providing an opportunity to assess the intersection for any pedestrians or oncoming traffic. The full stop allows drivers to observe and yield the right of way as necessary, reducing the risk of accidents. It's important to recognize that this requirement emphasizes safety and awareness at intersections, where the potential for collisions is heightened. By mandating a complete stop, the sign helps drivers make informed decisions about when it is safe to continue. Proper adherence to stop signs contributes significantly to the orderly flow of traffic and the protection of all road users.
