MUNTINLUPA CITY — Three members of a family were killed, while three others were injured after a truck crashed into their car on the northbound lane of the South Luzon Expressway (SLEX) in the Alabang–Muntinlupa area early Tuesday morning.

According to a report by GMA Integrated News, the sedan carrying six family members was struck by a truck at around 5:00 a.m. Three passengers died at the scene, while three others, including a five-year-old child, sustained injuries and were rushed to the nearest hospital for treatment.

The Philippine National Police Highway Patrol Group (PNP-HPG) confirmed that the truck driver is now in police custody. Authorities are conducting an investigation to determine the cause of the crash and assess potential liability. Efforts are also underway to obtain the driver’s statement regarding the incident.

The collision caused heavy traffic along the affected stretch of SLEX, one of the country’s busiest expressways. Emergency responders carried out clearing operations to restore traffic flow as soon as possible.

The tragedy once again highlighted concerns over road safety on major expressways. Authorities noted that accidents along SLEX are often linked to overspeeding, driver fatigue, and inadequate vehicle maintenance.

Relatives of the victims have called for justice and stricter regulation of trucks operating on major highways.

A Family Lost, and the Safety Gaps We Keep Ignoring

This crash along SLEX is not just another traffic statistic. It is a reminder of how fragile safety becomes when speed, fatigue, and heavy vehicles collide on public roads. A family lost three loved ones in minutes. That reality should unsettle everyone who uses the country’s expressways.

Major highways are built for efficiency, but efficiency without discipline invites disaster. Overspeeding trucks, exhausted drivers, and poorly maintained vehicles turn expressways into danger zones, especially during early morning hours when vigilance drops. These risks are known. What remains lacking is consistent enforcement.

Truck regulation deserves closer scrutiny. Heavy vehicles carry greater destructive force, yet monitoring of driver hours, vehicle condition, and speed compliance often falls short. When accountability only comes after lives are lost, the system has already failed.

This tragedy also raises questions about deterrence. Are penalties strong enough to change behavior? Are inspections frequent enough to catch risks before they escalate? Families should not pay the price for regulatory gaps.

Road safety is not about reacting to crashes. It is about preventing them. Until enforcement becomes predictable, strict, and visible, expressways like SLEX will continue to claim lives that never should have been at risk in the first place.
