VISTA, CA – Two women were killed and a man suffered serious injuries in a four-vehicle crash on state Route 76 in Vista, authorities said Tuesday.

It happened around 6:30 p.m. Monday on eastbound state Route 76 near East Vista Way, California Highway Patrol Officer Mark Latulippe said.

A 40-year-old man was driving a 2014 Chevrolet Silverado pickup in the left lane of eastbound state Route 76 when he swerved in an attempt to avoid a 2018 Hyundai Sonata that had stopped for traffic at the intersection, Latulippe said.

The pickup struck the rear of the Hyundai, sending the sedan into the back of a 2016 Mazda SUV, which then struck the back of a 2016 Ford Fusion, Latulippe said.

Two women in the Hyundai were declared dead at the scene and a man, who was also in the Hyundai, was transported to Palomar Medical Center with major injuries, Latulippe said.

No details about the victims were immediately available.

The occupants of the Mazda and the Ford were uninjured in the crash.

Alcohol or drugs were not believed to have been factors in the crash, Latulippe said.
