At least 13 people were killed and a dozen or more were injured, including a teenager, on Tuesday when a vehicle packed with at least 25 passengers collided with a tractor-trailer in California just north of Mexico, according to hospital officials and the California Highway Patrol.

Jake Sanchez, a CHP spokesman, said the fatal collision occurred when an SUV drove into the truck’s path about 6:15 a.m. near a remote farming town about 15 miles north of the border, on Highway 115 at Norrish Road. The Ford Expedition, which has seating for up to eight passengers, was transporting at least three times as many people when the crash occurred, Sanchez said.

The SUV was traveling westbound when it reached the intersection. It was unclear whether either vehicle stopped before the truck slammed into the driver side of the SUV. The 22-year-old driver of the SUV was among those killed, Sanchez said. The truck driver, 69, was being treated at the Desert Regional Medical Center in Palm Springs.
