California Vehicle Code Section 21966 and local ordinances establish the framework for bike path usage, but many paths operate under a patchwork of state, county, and municipal regulations. Most California bike paths are designated as "Class I bikeways" or "multi-use trails," meaning they're separated from motor vehicle traffic and intended for shared use by pedestrians, cyclists, and sometimes equestrians or skaters. The California Department of Transportation (Caltrans) Highway Design Manual provides design standards, but enforcement and liability rules vary significantly by jurisdiction.
Pedestrians generally have the right to use bike paths unless specifically prohibited by posted signage. However, path etiquette and legal expectations differ from sidewalk rules. On most California bike paths, faster-moving users (cyclists) must yield to slower users (pedestrians) when passing, announce their presence audibly, and maintain safe speeds. Pedestrians are expected to stay to the right side of the path, avoid sudden movements into the path of oncoming traffic, and remain aware of their surroundings. When accidents occur, courts examine whether both parties followed these established norms.
The legal concept of "comparative negligence" plays a critical role in bike path accident cases. California follows a pure comparative negligence system, meaning even if you were partially at fault for the accident, you can still recover damages reduced by your percentage of fault. For example, if you were wearing headphones and didn't hear a cyclist's warning before being struck, you might be found 20% at fault, reducing your $100,000 claim to $80,000. Understanding these nuances is essential when building your case.
