TUBA, Benguet — A weekend transit routine along one of the primary mountain highways leading to the Cordillera highlands turned into disaster following a violent multi-vehicle pileup. A major three-vehicle collision along Marcos Highway has left one woman dead and at least 95 others injured.
The fatal accident transpired on Saturday evening, May 30, 2026, in Sitio Caucalan, Barangay Taloy Sur, a mountain terrain section of Tuba notorious for sharp curves and sudden visibility drops.
According to an official field log released late Sunday by the Tuba Municipal Disaster Risk Reduction and Management Office (MDRRMO) and local police investigators, the pileup involved two large passenger buses and a private sports utility vehicle (SUV).
The dynamic flow of the crash points to structural brake or maneuvering failure during a steep decline:

Because of the massive scale of the passenger count involved across both transit buses, local response structures were instantly overwhelmed, requiring emergency reinforcement units from neighboring Baguio City.

Marcos Highway, while wider and generally considered safer than the historic Kennon Road, presents extreme operational risks for heavy commercial buses due to sustained gravity loads on braking systems during long descents from Baguio.

Tuba local government officials have renewed their public appeals to commercial transport operators to stringently enforce mandatory mechanical inspections before routing multi-ton vehicles down the Cordillera mountain passes. With almost a hundred families impacted by the weekend crash, the tragedy highlights the persistent structural vulnerabilities of long-haul mountain transit. Field clearing crews successfully righted the overturned bus using heavy tow cranes to reopen the vital commerce corridor, while municipal investigators lock down their final accident reconstruction reports to determine the exact technical or human failure that triggered the pileup.
