Multiple law enforcement, fire, and rescue agencies were dispatched to the accident about 2:30 p.m., after 911 callers reported a rear-end collision that sent two vehicles careening directly into the path of an oncoming big-rig.

Based on the circumstances, City of Hemet Police and Fire, California Highway Patrol, Riverside County Sheriff’s Department, Cal Fire/Riverside County Fire Department, and American Medical Response were all dispatched to the scene of the wreck.

When officials arrived they found black Mercedes-Benz sedan and black Saturn SUV blocking the westbound lanes of Domenigoni Parkway. The Mercedes had sustained major passenger side and front-end damage and the Saturn sustained heavy front-end damage.

A gold Chrysler minivan was parked in the center divider of the eastbound lanes and a rented tandem-trailer bottom dump big-rig with moderate front-end damage was parked off the north side of the roadway, facing west.

Vehicle parts and debris were spread across more than 150 yards of Domenigoni and westbound traffic was unable to continue due to the wrecked vehicles blocking the roadway.

Firefighter/Paramedics began evaluating and treating the victims injured in the crash. The  occupants from the Mercedes and Saturn were eventually transported to a local trauma center with major traumatic injuries.

The driver of the semi truck was transported with minor injuries and the driver of the minivan was evaluated at the scene and declined further treatment.

While rescue personnel treated the victims of the crash, CHP investigated the cause of the wreck. Officers determined that just before the accident the Saturn, Mercedes, and Chrysler were all traveling eastbound on Domenigoni approaching the intersection. At the same time, the tandem-trailer big-rig was traveling westbound.

Witnesses at the scene later told John Strangis of Hemet Eye News that the Saturn rear-ended the Mercedes, causing both vehicles to careen across the dirt median and into the westbound lanes of traffic, directly into the path of the semi-truck. Unable to stop in time, the big-rig plowed broadside into the Mercedes.

It was not immediately known how the Chrysler was involved in the collision.

CHP’s investigation is ongoing and officials are still working to determine if alcohol or drug intoxication were contributing factors in the crash.

  • Is this a misprint or accident? How can all of the vehicles be traveling eastbound? It is not possible to all be traveling eastbound at the same time & end up in such a tragedy. Officers determined that just before the accident the Saturn, Mercedes, and Chrysler were all traveling eastbound on Domenigoni approaching the intersection. At the same time, the tandem-trailer big-rig was traveling eastbound.
