The 14 Freeway was the site of tragedy on the early morning of Sept. 29 after a serious collision killed two people, according to authorities. The California Highway Patrol has confirmed the death of two women in their 60s following a motor vehicle accident involving a construction vehicle. Police have not yet determined the cause of the crash, but they believe speed may have been a contributing factor.

According to the accident report, just after 5 a.m. California Highway Patrol received word that a minor rear-end crash had occurred on the north side of the highway. While the two parties involved were exchanging insurance information, the driver of one of the vehicles accelerated rapidly away from the accident scene. She made it approximately a half mile before her vehicle crashed into an attenuator truck inside a closed construction zone, causing the roof of her vehicle to be ripped off.

While attenuator vehicles are designed to absorb impacts, police still believe the force of the crash was what killed the 60-year-old female driver and her 68-year-old female passenger. Both were declared dead at the scene. No other injuries were reported. Clean up crews were still working with accident reconstruction later in the morning of the same day to determine the cause of the second accident.

A fatal motor vehicle accident requires considerable investigation before California authorities are satisfied with presenting a cause for such a crash. In cases of this nature, investigators typically seek to determine whether the driver was intoxicated at the time of the crash. Of course, no criminal charges are filed posthumously, but if the cause of the accident is deemed the fault of the driver, the passenger’s family could be entitled to file a wrongful death lawsuit in civil court against the driver’s estate, as well as anyone with ownership interest in the vehicle.
