The "right of way" refers to the legal right of a person or vehicle to proceed first in a particular situation, especially in traffic. It helps prevent accidents by establishing rules about who goes first at intersections, crosswalks, and other shared spaces. For example, vehicles must yield the right of way to pedestrians in a crosswalk. In many places, specific laws dictate the right of way for different types of vehicles, such as cars, bicycles, and emergency vehicles like ambulances. Understanding these rules is essential for safe navigation on roads and pathways, ensuring that everyone can travel without conflict.
