When can you drive in a bike lane in ca?

In California, you can drive in a bike lane only when you are making a right turn at an intersection or when you are entering or leaving a driveway or private road. However, you must yield to any cyclists in the bike lane before merging into it. It is also prohibited to drive in a bike lane during the hours when it is marked with "no parking" signs, unless you are actively engaged in the allowed maneuvers. Always ensure to follow local regulations, as they may vary.
