HAYWARD, California — October 29, 2026 — A Tesla Semi truck fire that forced the closure of Interstate 880 in Hayward has drawn attention after flames erupted from the electric heavy-duty vehicle during the evening commute on Tuesday, October 27. The incident prompted a major emergency response and disrupted traffic in both directions because of concerns about potentially hazardous smoke. All lanes were reopened early Wednesday morning, according to the California Highway Patrol (CHP).
What Happened in the Tesla Semi Truck Fire?
The fire was reported at approximately 5:35 p.m. Tuesday in the southbound lanes of Interstate 880 near the Highway 92 interchange in Hayward, in California’s Bay Area.
According to authorities, the Tesla Semi caught fire while traveling on the freeway. The driver reportedly told patrol officers that the truck had caught fire but could not explain what caused the incident. No collision involving other vehicles was reported.
The CHP closed both northbound and southbound lanes between Winton Avenue and Highway 92 shortly afterward. Officials cited the potential danger posed by hazardous smoke from the burning electric truck’s battery.
Lithium-Ion Battery Fire Creates Challenges
The incident involved the truck’s lithium-ion battery, which presented challenges for emergency responders attempting to extinguish the flames.
Lithium-ion battery fires can be difficult to control because damaged battery cells may continue generating heat and can potentially reignite. Such incidents can also expose nearby people to hazardous substances, making it important for firefighters to follow specialized response procedures.
Authorities initially warned that the fire could burn for an extended period. Fire crews continued working at the scene while officials assessed the risks and determined when it would be safe to reopen the affected highway.
Interstate 880 Reopens After Hours of Closures
The highway closures caused significant disruption for motorists traveling through Hayward during the evening and overnight hours.
Northbound lanes reopened at approximately 8:40 p.m. Tuesday, while the southbound lanes remained closed for several additional hours. The CHP announced that southbound traffic could resume around 3:30 a.m. Wednesday, October 28.
Officials reported no injuries connected to the incident. The truck’s driver was able to leave the vehicle safely, and no other vehicles were reported to have been involved.
Investigation Into the Cause Continues
The exact cause of the Tesla Semi fire remains under investigation. Authorities have not established whether a mechanical issue, battery malfunction, or another factor triggered the blaze.
The incident raises questions about emergency response procedures for large electric trucks, particularly when battery fires occur on busy highways.
As of October 29, 2026, the fire has been extinguished and Interstate 880 has reopened. Investigators are continuing to examine the circumstances surrounding the incident, and further verified information may clarify what caused the truck to catch fire.
The incident serves as a reminder for motorists to follow official traffic alerts, avoid emergency scenes, and use alternative routes when authorities announce road closures.
