What should you do if you encounter a pedestrian at a crosswalk?

Answer: B — Yield your vehicle to the pedestrian

Yielding your vehicle to the pedestrian is the correct action to take at a crosswalk. This reflects the fundamental principle of road safety that prioritizes the safety of pedestrians, who are more vulnerable road users. When a pedestrian is at a crosswalk, they have the right of way, meaning drivers must stop and allow them to cross safely. Understanding this requirement is crucial for fostering a safer driving environment and helps to prevent accidents involving pedestrians. By yielding, you are demonstrating responsible driving behavior and complying with traffic laws designed to protect individuals on foot. The other options do not align with safe driving practices or legal requirements. Honking can be perceived as aggressive and does not provide meaningful assistance to a pedestrian. Speeding up can lead to dangerous situations and increases the risk of a collision. Stopping only if the pedestrian is crossing ignores their right to be given way as soon as they approach the crosswalk.
