You might remember San Diego cyclist Andrew Woolley, who received a ticket for failing to stay far to the right when he split the lane through heavy traffic. The traffic court judge upheld the ticket.
Woolley appealed the conviction and the appellate court filed a brief acknowledging Woolley didn't violate CVC 21202, which is California's Ride Far to the Right law. The San Diego Superior Court Appellate Division acknowledged that CVC 21202 did not apply to Woolley because the cyclist was riding "at a speed less than the traffic at that time."
Serge Issakov, who followed this case in San Diego, also notes, "For what it's worth, the appeals court also noted that Andrew may have been in violation of 22350." This is the California Basic Speed Law.
