What is a common cause of signal malfunctions?

Electrical failures or damaged wiring are indeed common causes of signal malfunctions. Signals rely on a complex network of electrical components, including wiring, circuitry, and power sources. When any part of this system is compromised—whether through physical damage, environmental factors, or age—it can lead to incomplete signals, incorrect functioning, or total failure of the traffic signal system. Additionally, faulty wiring can create intermittent issues that may result in inconsistent signal performance, making it crucial to regularly inspect and maintain these electrical components to ensure reliable operation. This understanding underlines the importance of proactive maintenance and monitoring in traffic signal management to prevent malfunctions that could disrupt traffic flow and safety.
