What should drivers do when they see a pedestrian waiting to cross at a crosswalk?

Answer: B — Stop and allow the pedestrian to cross

When drivers see a pedestrian waiting to cross at a crosswalk, the appropriate action is to stop and allow the pedestrian to cross. This is crucial for ensuring the safety of pedestrians, as they have the right-of-way at marked crosswalks. Stopping for pedestrians not only demonstrates good driving etiquette but also complies with traffic laws designed to protect vulnerable road users. By stopping, drivers provide the necessary space and time for pedestrians to safely navigate the crossing. This contributes to a safer environment for all road users and helps to prevent accidents. It's essential for drivers to recognize that pedestrians may require additional time to cross, particularly those who are elderly or have mobility challenges. In contrast, continuing to drive when approaching a crosswalk, even if moving quickly, poses a significant risk to pedestrians. Waving for pedestrians to hurry might encourage unsafe behavior and could lead to accidents. Moreover, stopping only if a pedestrian is directly in the crosswalk does not consider those who may be waiting to cross, thereby potentially endangering them as well. Overall, the safest and legally mandated choice is for drivers to stop and allow pedestrians to cross at crosswalks.
