At what point must a driver yield to a pedestrian in a marked crosswalk?

A driver must yield to a pedestrian in a marked crosswalk when the pedestrian is in the crosswalk because this is a fundamental traffic rule designed to ensure the safety of pedestrians. The law clearly states that once a pedestrian has entered the crosswalk, they have the right of way. This requirement emphasizes the importance of being cautious and aware of pedestrians near these designated areas, ensuring that drivers stop in time and allow pedestrians to cross safely.

Yielding in this situation is about protecting the pedestrian's safety, as crosswalks are specifically established to provide a safe passage for individuals crossing the road. A driver should remain vigilant and attentive to pedestrians approaching or present in the crosswalk to prevent accidents and promote road safety for all users.
