Heavy Trailer Triggers Multi-Vehicle Crash on Mexico–Querétaro Highway

On Wednesday, November 20, chaos erupted at kilometer 59 of the Mexico–Querétaro Highway near Huehuetoca, State of Mexico, when a heavy trailer lost control and caused a chain-reaction crash.
The runaway vehicle struck a roadside bank before colliding with five cars and a pickup truck, blocking all three lanes and forcing a partial closure that backed up traffic for miles.

Slick Roads and Speed Blamed

Early reports indicate that wet pavement from earlier rain left the road slick and reduced braking power.
Witnesses said the trailer appeared to be moving too fast for the conditions, giving the driver no time to stop.
Investigators are checking for possible brake problems, driver fatigue, or maintenance issues as contributing factors.

Emergency Response

Paramedics arrived within minutes and treated several people for minor injuries.
Fortunately, no fatalities were reported—an unusually positive outcome given the number of vehicles involved.
Rescue teams worked to clear debris and contain potential fuel leaks while police redirected traffic to alternate routes.

Later that afternoon, another trailer accident at kilometer 95.5 near Soyaniquilpan de Juárez spilled fuel across the roadway.
This second emergency forced a complete closure in both directions for hours as hazmat crews cleaned the scene.

Ripple Effects and Safety Concerns

The Mexico–Querétaro Highway is a key trade corridor linking Mexico City to the Bajío industrial region.
Wednesday’s shutdowns delayed shipments, stranded commuters for hours, and reignited calls for stricter inspections, lower rain-speed limits, and better rest enforcement for truck drivers.

Authorities have pledged a full investigation into both incidents and reminded motorists to slow down and maintain safe distances during wet weather.
