Step-by-step explanation:
When you encounter a pedestrian or bicyclist crossing the street within a clearly marked crosswalk or unmarked intersection, you must always yield the right-of-way to the pedestrian or bicyclist.
This is in accordance with traffic laws that prioritize pedestrian safety, acknowledging that pedestrians and other vulnerable road users should be able to cross safely without the need to dodge traffic. Installing a traffic signal at busy intersections can further enhance safety by providing designated crossing times, reducing the likelihood of vehicles speeding through intersections without regard for pedestrians.
