Final answer:
True, every intersection where streets with sidewalks meet at right angles constitutes a crosswalk for pedestrians to cross the street, even without painted lines.
Step-by-step explanation:
The statement, 'Every intersection where streets with sidewalks meet at about right angles, constitutes a crosswalk for pedestrians to cross the street, even if there are no painted lines,' is true.
In urban areas, crosswalks are typically marked with painted lines for visibility. However, even if there are no painted lines, pedestrians still have the right of way at intersections where streets and sidewalks meet at right angles. This is because pedestrians are expected to be able to cross the street at these intersections, and drivers are required to yield to pedestrians in crosswalks.
For example, in cities like New York, pedestrians often have to follow roads and sidewalks that make two-dimensional, zigzagged paths. Figure 3.2 shows how walkers and drivers rarely travel in straight lines to reach their destinations. Therefore, even without painted lines, pedestrians can still cross the street safely at intersections.
