The absence of functional traffic signals at an intersection presents a specific set of challenges for drivers, pedestrians, and cyclists. It fundamentally alters right-of-way rules, requiring all users to exercise significantly increased caution and awareness. For example, if all lights at an intersection are dark due to a power outage, the normal flow of traffic is disrupted, potentially leading to confusion and increased risk of accidents.
Understanding the appropriate procedures during signal malfunctions is crucial for maintaining traffic safety and minimizing disruptions. Historically, the response to non-operational traffic lights has evolved alongside advancements in traffic management and communication technologies. Prior to widespread signalization, intersections relied on rudimentary signage or the judgment of road users. Modern understanding emphasizes treating such intersections as all-way stops, a practice designed to ensure equitable distribution of right-of-way and prevent gridlock.
