Video footage captured by a motorist's dashboard camera shows a 10-wheeler truck slamming into several vehicles and causing two vehicles to hit the center island along the C-5 Ortigas Flyover on Tuesday morning.
The incident killed one person and injured at least four others.
Pasig City Police said the fatality was a motorcycle rider who got stuck underneath the truck.
The truck driver admitted he caused the incident and said he was on his way to Quezon City from Pasig when the vehicle's brakes allegedly failed.
"Medyo, ano, palusong na... Medyo alalay ako sa preno. Siyempre aapak akong preno, alalay, bigla akong nawalan ng preno. Ayun po ang nangyari," he said.
Authorities completed the removal of vehicles along C-5 Avenue at around 1:05 p.m.
