Buenos Aires Highway Crash: Multi-Vehicle Collision Leaves Three Dead and Blocks Major Traffic Corridor

Buenos Aires, Argentina—A violent multi-vehicle collision involving two trucks and several passenger cars crippled a major highway corridor outside Buenos Aires early Wednesday afternoon, leaving three people dead at the scene. The impact crushed the cabin of a small delivery van caught in the middle of the pileup. Twisted metal and shattered glass covered all three southbound lanes. Emergency medical units rushed to the site as plumes of thick black smoke rose from a burning vehicle.

Highway police confirmed three fatalities among the occupants of the crushed vehicles trapped beneath the truck trailer. Paramedics treated four other motorists for severe polytrauma before transferring them to municipal hospitals under police escort. Traffic behind the crash backed up for miles, creating a standstill that paralyzed commercial transport entering the capital. Crews worked under heavy rain to cut open trapped vehicle frames using hydraulic rescue tools.

Preliminary accident investigations suggest poor visibility and sudden braking triggered the initial chain reaction. A heavy grain truck failed to slow down in time, plowing directly into the back of a slowed commuter queue. State road safety inspectors seized the tachograph disks from the commercial freight trucks involved in the smashup. Both truck drivers survived with minor injuries and were detained for questioning by federal prosecutors.

Civil defense teams deployed chemical foam to neutralize fuel spills spreading across the wet asphalt. Cranes arrived at the scene to separate the locked vehicles and clear the highway lanes. Municipal traffic authorities diverted incoming vehicles onto parallel rural routes, causing massive congestion across secondary roads. Transit police officers established a wide safety perimeter to keep curious motorists moving along the detour.

Forensic units marked evidence points across the pavement to reconstruct the precise sequence of impacts. Representatives from the national transport secretariat arrived to review safety compliance records of the freight companies. Drivers trapped in the multi-mile traffic jam turned off their engines, stepping out onto the road shoulders to survey the delay. Tow operators labored for hours to winch the wrecked trucks onto heavy flatbed transports.

Road maintenance crews began repairing damaged concrete jersey barriers that absorbed the brunt of the kinetic energy. Officials warned that full restoration of normal traffic flow would take several hours into the evening. The national highway agency reiterated warnings about speed limits during adverse weather conditions. Forensic pathologists transferred the bodies of the victims to the city morgue for formal identification.

The highway remains restricted to a single lane as cleanup operations continue under artificial lighting. Investigators are reviewing automated toll camera footage to calculate the exact speed of the vehicles prior to impact. Families of the victims have been notified through municipal social assistance teams. The investigation remains active and open.
