Authorities are investigating a tragic highway crash that killed four people and critically injured two others after multiple tractor-trailers collided with passenger vehicles on an Arizona interstate Saturday afternoon.
Thick smoke blanketed the roadway as firefighters worked to extinguish flames from at least seven burning vehicles. The wreck led to extensive road closures and significant traffic disruptions west of Phoenix.
According to the Arizona Department of Public Safety, six additional people sustained injuries, with five treated and released from the hospital. The fatal crash occurred near Tonopah, approximately 50 miles west of Phoenix.
At least two tractor-trailers came to rest on the highway shoulder, while multiple passenger vehicles were crumpled together, charred and covered in soot.
Authorities are examining whether an initial crash—potentially triggered by poor visibility due to blowing dust—set off a chain reaction of secondary collisions.
Emergency responders from three fire departments rushed to the scene, deploying over 20 units to manage the crisis, Arizona Fire and Medical Authority spokesperson Matt Licardi said.
The crash involved multiple tractor-trailers, several passenger vehicles, and an RV. Eight people were transported to hospitals, with one critically injured victim airlifted by helicopter.
The investigation remains ongoing as officials work to determine the exact cause of the deadly collision.
