Cycling Laws » USA » CA – California » California Vehicle Code
There are no federal laws outlining rules of the road. Instead, each state has its own set of traffic laws. In many cases, these are based at least in part on the Uniform Vehicle Code.
The California Vehicle Code governs bicycling in the state.
In addition to this, many counties, cities/towns, campuses, & military bases may have their own traffic regulations, usually known as ordinances or codes.
These local regulations may not take away any rights listed in the state traffic laws, unless this option is expressly permitted by the state. They also may not permit a person riding a bike to do anything prohibited by state law.
See below for the state laws that influence your bicycle riding in California.
