A pedestrian is in life-threatening condition after being struck by a driver while walking at 19th Avenue and Junipero Serra Boulevard.

The incident occurred in the early hours of Sunday morning, around 3:15 a.m. The victim, a 22-year-old man, was struck by a 37-year-old man traveling southbound on 19th Avenue in a red Toyota Prius. 

The pedestrian was transported to the San Francisco General Hospital in life-threatening condition, police said Sunday. The driver remained at the scene to cooperate with the police, and was not arrested. 

“The intersection where [the pedestrian] was hit is notoriously dangerous, with fast-moving traffic,” said Jodie Medeiros, executive director of pedestrian advocacy organization Walk San Francisco. "It’s right in the middle of where a 65 mph highway transitions into a neighborhood street, where thousands of students attend San Francisco State University."

SFPD's investigation unit for traffic collisions is investigating the case, officials said. The intersection has been identified as a high-injury corridor under the city's Vision Zero plan, which aims to eliminate traffic fatalities in San Francisco by 2024.
