Three people riding bicycles on Mulholland Highway suffered major injuries Monday when they collided with an 81-year-old Calabasas woman making a left turn, authorities said.
The cyclists were westbound on Mulholland Highway approaching Stokes Canyon Road at 7:30 a.m. when an eastbound Audi A-4 driven by the woman attempted to make a left turn, said California Highway Patrol Officer Francisco Villalobos.
Investigators were on the scene to determine who was at fault, Villalobos said.
Los Angeles County firefighters airlifted the three injured riders to UCLA Medical Center, Villalobos said.
The names of the Audi driver and bicycle riders were not immediately available.
A fourth cyclist suffered minor injuries and was released, authorities said.
