A driver who lost control and crashed her vehicle into a group of people waiting for a bus in San Francisco on Tuesday was not licensed, police said.

The Tuesday morning crash injured five people. Two victims are in critical condition, and the other three were listed in serious condition at San Francisco General Hospital.

The 24-year-old driver was cited for driving a vehicle without a license and released, Police Capt. Louis Cassanego told the San Francisco Chronicle. Her name has not been made public.

At least four of the victims have suffered fractures, with the extent of any other injuries still not known, said Rachael Kagan, a hospital spokeswoman.

The crash occurred shortly after 9:30 a.m. in the city's Visitacion Valley neighborhood.

The driver apparently lost her ability to steer and brake as her gray Ford Explorer came down a hill while traveling southbound on San Bruno Avenue, said Lt. Mindy Talmadge, a spokeswoman for the San Francisco Fire Department.

The vehicle veered onto a sidewalk and slammed into a recessed area of an apartment building where people were seeking shade from the sweltering sun while waiting for a bus, San Francisco police Sgt. Michael Andraychak said.

The victims range in age from their 30s to 80s, Kagan said.

The driver remained on the scene and cooperated with investigators, Andraychak said. The vehicle was towed away Tuesday afternoon to check for any defects, Andraychak added.
