Bicyclists need to follow the rules of the road as outlined by the California Vehicle Code,

You may be cited for running stop signs, riding at an unsafe speed for conditions, riding on the wrong side of the road or on sidewalks, wearing headphones over both ears while riding, not having legal brakes and lights, etc. Cyclists are required by state law to use front white lights, rear red reflectors, and pedal and side reflectors at night. Additional lights, especially rear red flashers, extra reflectors, and light colored clothing are a good idea. We also recommend that you not talk on a cell phone or text while riding.

While riding your bicycle, obey all traffic laws and wear a bicycle helmet for every ride, even short trips. Helmets can greatly reduce the risk of head injuries and death. In addition, defensive cycling is a key to bicycle safety. According to the California Vehicle Code, every person riding a bicycle on a street or highway has all the rights and responsibilities of the driver of a vehicle.
