What should a driver do if they see a pedestrian in a crosswalk?

Answer: B — Yield and allow the pedestrian to cross

When a driver sees a pedestrian in a crosswalk, the appropriate action is to yield and allow the pedestrian to cross. This is crucial for ensuring the safety of individuals on foot, as pedestrians have the right-of-way in marked crosswalks under Maryland law. By yielding, drivers demonstrate respect for the rules that are designed to protect vulnerable road users and help prevent accidents. Honing or trying to get the pedestrian's attention, as suggested in other options, can be distracting and may not effectively communicate the driver's intention. Speeding up to pass or ignoring the pedestrian altogether poses significant danger to the pedestrian and is not in accordance with traffic laws. Prioritizing pedestrian safety by yielding not only complies with the law but also promotes a safer community for everyone.
