What could happen if a traffic signal is malfunctioning?

A malfunctioning traffic signal can significantly increase the risk of accidents and traffic congestion. When a traffic signal is not functioning properly, drivers may not have clear guidance on when to stop or proceed, leading to confusion at intersections. This confusion can lead to misjudgments and collisions, especially in high-traffic areas.

Moreover, malfunctioning lights can disrupt the normal flow of traffic, causing vehicles to stop or change directions unexpectedly. As a result, this can create bottlenecks and further increase congestion, as vehicles back up waiting for unclear instructions. Increased accident rates and traffic congestion are direct consequences that highlight the importance of maintaining properly functioning traffic signals for road safety and efficient traffic management.
