Authorities said the crash occurred two minutes after midnight on the shoulder of the highway south of Washington.

Police said the man had pulled his car to the shoulder of the northbound lanes of the highway. He was standing next to his car when a Hyundai Santa Fe Sport Utility Vehicle hit him. The man, whose identity and age were not immediately released, was pronounced dead on the scene, police said.

Authorities said the northbound lanes of I-95 at mile marker 162 were closed throughout the night and reopened at 9:15 a.m.Saturday.

Police said authorities found the Hyundai Saturday in Prince George’s County, but they did not elaborate.
