What should a driver do if they encounter a pedestrian at a crosswalk?

Answer: B — Yield the right of way to the pedestrian

Yielding the right of way to pedestrians at crosswalks is a fundamental rule in traffic safety and is essential for ensuring the safety of those on foot. When a driver approaches a crosswalk and sees a pedestrian preparing to cross, they must slow down or stop to allow the pedestrian to safely complete their crossing. This rule is in place to protect vulnerable road users, as pedestrians do not have the same level of protection as vehicle occupants. Yielding demonstrates not only compliance with traffic laws but also an understanding of the importance of pedestrian safety. It fosters a more cooperative relationship between drivers and pedestrians, which can significantly reduce the risk of accidents. The other options present unsafe or illegal behaviors that can endanger pedestrians. Speeding up to pass a pedestrian can lead to dangerous situations, while honking might be seen as aggressive or confusing to the pedestrian. Continuing to drive without stopping outright disregards the right of way laws, putting the pedestrian at risk.
