Final answer:
When a traffic control sign is not functioning, the intersection usually becomes a four-way stop. Drivers must yield right-of-way to pedestrians and other vehicles according to standard right-of-way rules. Pedestrian safety and vehicle speed control are crucial reasons for the functionality of traffic signals.
Step-by-step explanation:
When a traffic control sign is not functioning at an intersection, the intersection shall revert to a four-way stop in most jurisdictions. This means that all drivers approaching the intersection must stop and yield the right-of-way to pedestrians and other vehicles that have arrived before them or to the vehicle that is to their right if they arrive at the same time. The lack of a working traffic control signal at such an intersection demands extra caution because some drivers might erroneously speed through the intersection, unaware that the traffic signal is inoperative. Furthermore, pedestrian safety becomes a critical issue when traffic signals that are meant to protect individuals crossing are not working. Traffic signals are essential for regulating vehicle speed, pedestrian safety, and reducing accidents. The need for such measure was underscored by the number of accidents reported at one specific intersection, which significantly dropped after the installation of a traffic signal.
