Mexico City, Mexico—A head-on collision on Highway 15 killed four people this morning. The accident involved a passenger sedan and a transport truck at a narrow curve known for poor visibility. State Highway Patrol officers arrived at the scene within twenty minutes, but all four occupants of the smaller vehicle were already deceased.

The truck driver was treated for minor injuries and shock at a nearby regional hospital. Officers have cordoned off a three-kilometer stretch of the highway to facilitate the removal of wreckage. Traffic is being rerouted through local auxiliary roads until the scene can be fully cleared.

Evidence suggests the sedan crossed the center line before impact. Investigators are now checking if mechanical failure or driver error caused the vehicle to drift into oncoming traffic. Brake marks are being analyzed by specialists to determine the speed of the vehicles before the crash.

"We are documenting every inch of the road surface," said a patrol sergeant overseeing the cleanup. The process of extracting the bodies from the crushed metal took several hours. The highway remains a restricted zone as debris removal teams continue their work.

Local residents near the crash site reported hearing the impact from over a kilometer away. This section of the road is frequently used by heavy transport vehicles, increasing the danger of high-speed collisions. Improvements to the road’s design have been requested by municipal leaders for months.

State officials have not yet confirmed the identities of the deceased. Information remains sparse while the coroner finishes the preliminary site assessment. The victims are believed to be traveling toward the state capital for the weekend.

The Highway Patrol is emphasizing the importance of staying within lane markers during low-visibility conditions. A full report on the cause of the accident will be compiled over the next several days. The highway is expected to remain blocked until the wreckage is removed and the pavement is cleaned of fluids and debris.

Engineers will evaluate the safety of this specific curve later this week. Patrol units will increase their presence on this route to monitor compliance with speed limits. The investigation is still ongoing.
