A devastating multi-vehicle accident occurred on the Bicentennial Bypass in Lerma, State of Mexico, leading to a significant loss of life and injuries. The incident left three people dead and 15 others injured, with approximately 40 vehicles involved in the wreck. The initial crash began near kilometer 3 of the Lerma-Xonacatlán road and escalated as emergency responders arrived at the scene, highlighting the dangers that first responders face in such critical situations.

The sequence of events started with two separate accidents, with the first occurring on the highway, and the second involving a collision between a Red Cross rescue truck and a state ambulance as they responded to the scene. Poor visibility caused by thick fog and smoke from grass burning severely hampered emergency efforts, worsening an already tragic situation. The failure to navigate these hazardous conditions resulted in a chain reaction that compounded the disaster.

As the drivers attempted to avoid the initial collision, a Volkswagen Passat collided with a motorcycle, resulting in the motorcycle rider's death. The area was cordoned off after the accident, revealing the serious implications of driving in such adverse conditions. This incident raises awareness regarding road safety laws, handling emergencies effectively, and ensuring that first responders can operate without additional threats during their critical missions.
