The incident happened at about 6 p.m. Saturday at the intersection of Anaheim Street and Walnut Avenue.
Investigators say the officer was on his way to a checkpoint for unlicensed and impaired drivers. He was traveling westbound on Anaheim Street and about to pass through the intersection at Walnut Avenue on a green light when a blue Ford Focus traveling eastbound on Anaheim crashed into him.
Two other motorcycle officers were able to avoid the crash.
The 47-year-old driver of the car was cited for not having a license and making an unsafe turn.
