Over the weekend, San Francisco experienced a series of power outages due to a substation fire, affecting approximately 130,000 residences and businesses. Nearly 48 hours later, Pacific Gas and Electric reported that some locations still lacked electricity. As a result of this incident, the city learned how Waymo self-driving taxis respond when all traffic signals fail at once: Essentially, they do not function.
It wasn’t long before social media users began sharing videos of unmoving Waymo vehicles at intersections with flashing hazard lights. Bloomberg spoke to one passenger who stated that his ride ceased operating about a minute away from his destination at a busy intersection. After waiting several minutes and contacting customer service, he opted to exit the car and complete the journey by foot.
“The issue was that initially, many people were crossing the streets since there were no traffic lights,” the passenger remarked. “So I think the Waymo just became confused about what to do.”
Waymo temporarily suspended its service in the city around midday Sunday; it has since resumed operations. Although its vehicles are engineered to handle intersections with non-functional signals as four-way stops, the Google-linked autonomous ride-hailing service informed the New York Times that “the extensive nature of the outage resulted in situations where vehicles remained idle longer than typical to ascertain the status of the affected intersections. This contributed to traffic delays during peak congestion.”
Nonetheless, Tesla CEO Elon Musk took the chance to promote how his rival vehicles were reportedly unaffected by the infrastructure breakdown. This would be commendable, if Tesla’s Robotaxis didn’t still necessitate a human safety operator at the wheel at all times.

**Waymo Suspends Service in San Francisco Due to Traffic Signal Malfunction Resulting from Blackout**
In a notable interruption to its autonomous vehicle services, Waymo declared a temporary halt to its operations in San Francisco due to a widespread traffic signal malfunction caused by a recent blackout. This event emphasizes the vulnerabilities that autonomous driving technology encounters in urban settings, especially when depending on infrastructure that may fail.
The blackout, which impacted numerous neighborhoods in San Francisco, resulted in the failure of traffic lights, creating a chaotic driving atmosphere. Waymo, a frontrunner in autonomous vehicle technology, opted to pause its services to prioritize the safety of both its passengers and other road users. The company reinforced its dedication to safety and the critical need for working traffic signals for the effective navigation of its self-driving vehicles.
Waymo’s autonomous cars depend significantly on real-time information from traffic signals, street signs, and other infrastructure to function safely and efficiently. When these signals are non-operational, the vehicles struggle to interpret the traffic conditions, which can lead to potential dangers. The choice to suspend operations demonstrates a proactive strategy to minimize risks associated with navigating in circumstances where standard traffic management is disrupted.
The blackout and ensuing failure of traffic signals remind us of the interconnectedness of urban infrastructure and the challenges that arise when this infrastructure is interrupted. For cities increasingly integrating smart technologies and autonomous vehicles, assuring the reliability of traffic management systems is essential.
Waymo’s endeavors in San Francisco have been carefully observed as the company continues to test and enhance its autonomous technology within a complex urban environment. The temporary suspension of service is anticipated to be lifted once the traffic signals are repaired and conditions return to normal. In the meantime, Waymo is collaborating closely with city officials and utility providers to evaluate the situation and prepare for a safe resumption of its services.
As cities advance and adopt more sophisticated technologies, this incident underscores the necessity for robust infrastructure capable of supporting the safe operation of autonomous vehicles. The reliance on technology for traffic management requires ongoing investment and maintenance to avert similar disruptions in the future.
In summary, Waymo’s decision to halt operations in San Francisco due to the traffic signal malfunction illustrates the challenges autonomous vehicle companies face in urban settings. As technology continues to progress, guaranteeing the reliability of supporting infrastructure will be vital for the safe integration of self-driving cars into everyday traffic.
