Final answer:
It is generally not allowed to park or stop on a crosswalk as it can disrupt traffic flow and endanger pedestrians. Traffic signals at intersections help to regulate movement and enhance safety for all road users.
Step-by-step explanation:
No, a person is generally not allowed to park or stop for an extended period of time on a crosswalk. Crosswalks are designed to ensure pedestrian safety, especially in areas with heavy pedestrian traffic such as near a campus. Having a vehicle stopped on a crosswalk can disrupt the flow of traffic and endanger pedestrians trying to navigate the intersection.
In situations where traffic signals are present, they serve to regulate both pedestrian and vehicle movement, allowing pedestrians to cross at appropriate times. This becomes even more important in intersections where many vehicles tend to speed through without regard to the posted speed limit. The presence of a traffic signal forces vehicles to adhere to the traffic laws, which in turn protects the safety of pedestrians.
