NYC Traffic Signals Struggle to Recover After Brutal Winter
New York City’s traffic infrastructure is facing significant strain following a series of severe winter storms and a prolonged period of freezing temperatures. Reports of malfunctioning traffic signals have surged this year, leaving commuters to navigate increasingly complex intersections. The New York City Department of Transportation (DOT) is working to address the issue, but the scale of the problem—exacerbated by power outages and the impact of road salt on underground cabling—highlights the vulnerability of the city’s aging infrastructure. The situation is too impacting road conditions, with a notable increase in pothole complaints adding to the challenges faced by drivers and pedestrians alike.
As of this year, the city has received 15,543 complaints regarding broken traffic signals, a 42% increase compared to the same period in 2025, according to data confirmed by the DOT. The surge in issues is largely attributed to a blizzard last month that deposited as much as 24 inches of snow across parts of the city, as reported by Gothamist. The DOT stated that repair crews responded quickly, resolving signal malfunctions within an average of one hour and forty minutes. Yet, the sheer volume of incidents continues to pose a challenge.
Power Outages and Underground Infrastructure
The recent winter weather wasn’t limited to heavy snowfall. A wave of power outages swept across New York City, further complicating the situation with traffic signals. These outages, as well as melting snow and ice seeping into underground wiring, are key factors contributing to the increased number of faulty signals. According to a report by Gothamist, Con Edison has attributed some of the power disruptions to road salt damaging underground electrical cables. This suggests a broader issue with the city’s underground infrastructure and its susceptibility to winter weather conditions.
Many of the reported issues involve traffic signals flashing yellow, a condition caused by voltage fluctuations. While not as dangerous as a complete outage, flashing yellow lights require drivers to exercise increased caution and treat the intersection as a yield point. A flashing red light, conversely, should be treated as a stop sign, according to traffic safety experts.
A History of Infrastructure Concerns
The current crisis brings to the forefront long-standing concerns about the resilience of New York City’s infrastructure. Sam Schwartz, a former traffic commissioner, recalled the chaos caused by a widespread blackout in 2003, emphasizing the critical role of functioning traffic signals in maintaining order. “The traffic signals being out caused a massive problem as people tried to negotiate intersections,” Schwartz said. He has long advocated for increased investment in battery backups for traffic signals, a measure that would allow them to continue operating during power outages.
New York City was a pioneer in adopting LED traffic lights, completing the city-wide conversion in 2009. This initiative significantly reduced energy consumption by 81%, making the installation of battery backups more feasible, according to Schwartz. However, the city still has a limited number of intersections equipped with this crucial safety feature. Currently, only a fraction of the city’s 13,500 signalized intersections have battery backup systems.
Safety Risks at Darkened Intersections
The dangers associated with malfunctioning traffic signals are well-documented. A 2007 study commissioned by the New York State Department of Transportation found that individuals were almost twice as likely to be injured in crashes at intersections with non-functioning signals, often referred to as “dark signal crashes.” This underscores the importance of maintaining a reliable traffic signal system, particularly during inclement weather.
The DOT is actively working to address the surge in complaints, but the scale of the problem is significant. The agency has filled roughly 170,000 potholes annually in recent years, and is likely facing a similar workload with repairs to traffic signals. Alongside the signal issues, the city is also grappling with a rise in pothole complaints, with 13,649 reported so far this year, a typical increase following intense winter weather and plowing operations.
State of Emergency and Ongoing Recovery
The severity of the recent winter storms prompted Mayor Zohran Kwame Mamdani to declare a local state of emergency in February 2026. The declaration restricted non-essential vehicular traffic from 9 p.m. On Sunday, February 22nd, to 12 p.m. On Monday, February 23rd, to allow emergency responders and essential workers to navigate the city safely. Public schools were also closed on Monday, February 23rd, with no remote instruction taking place. The Emergency Weather Declaration also suspended Alternate Side Parking regulations for February 23rd and directed the Department of Consumer and Worker Protection to monitor for price gouging.
The DOT, along with other city agencies like the Fire Department, Police Department, and Department of Sanitation, are coordinating efforts to restore full functionality to the city’s traffic infrastructure. The focus remains on prioritizing safety and ensuring the efficient movement of people and goods, as outlined in the DOT’s mission statement. The DOT provides real-time traffic conditions and camera feeds on its website, NYC.gov, offering commuters up-to-date information on road conditions and traffic signal status.
Looking Ahead
The challenges faced by New York City’s traffic infrastructure this winter serve as a stark reminder of the need for continued investment in infrastructure resilience. While the DOT is actively addressing the current issues, a long-term strategy is needed to mitigate the impact of future severe weather events. This includes expanding the use of battery backups for traffic signals, strengthening underground cabling, and proactively addressing the root causes of power outages. The city is also encouraging residents to report any malfunctioning traffic signals through the 311 service.
The next scheduled update from the DOT regarding infrastructure repairs is expected in early April, as part of the agency’s quarterly report on citywide transportation projects.
