Maryland State Police told the Washington Post that the incident occurred around 7:40 p.m., when the driver of a Chevrolet Malibu hydroplaned on a curve and slid across the highway and spun into a Toyota pickup truck. A Chevrolet Silverado then hit the Malibu, police said.
Two passengers, a 30-year-old woman and 17-year-old male both from Silver Spring, were taken to hospitals with life-threatening injuries but later died, police said.
The 36-year-old driver of the Malibu also sustained serious injuries. All others involved had minor injuries, police said.
The crash closed all lanes of the outer loop near Connecticut Avenue on Monday night, as a light rain continued to fall in near-freezing temperaturs.
