The woman was crossing Ruth Avenue at El Camino Real about 5:25 p.m. when she was hit by a Honda turning right, Belmont Police Captain Patrick Halleran said. Paramedics treated her at the scene, then took her to the hospital with injuries that were not life-threatening.

The driver, a 26-year-old Belmont man, stopped for the stop sign but said he did not see the woman as she stepped off the curb, Halleran said. The driver is cooperating with investigators, who said drugs and alcohol do not appear to be a factor.

Police say bicyclists and pedestrians should never assume that drivers can see them and should be constantly on alert when riding their bikes or crossing the road.

"In this case, the pedestrian was wearing dark clothing and thought the driver saw her," Halleran said. "If possible, wear light-colored clothing or carry a flashlight when walking during darkness."
