What is the proper condition for a traffic signal that is functioning but intermittently flickering?

A traffic signal that is functioning but intermittently flickering indicates that there is an issue that needs to be addressed. Flickering can cause uncertainty for drivers and pedestrians, leading to potential safety hazards at intersections. While the signal is still operational, the intermittent flickering suggests that there is a malfunction or degradation in the system that could worsen over time.

Regular maintenance is essential for traffic signals to ensure they function reliably and safely. Therefore, identifying a flickering signal as needing maintenance aligns with best practices for traffic management. Proper functioning signals play a crucial role in managing traffic flow, preventing accidents, and ensuring the safety of all road users.

In contrast, options indicating the signal's condition as acceptable, marginal, or unacceptable do not accurately reflect the situation where flickering occurs. The focus should be on taking corrective action to prevent potential problems before they arise, reinforcing the idea that maintenance is necessary when any irregular operation is observed.
