cities have banned sidewalk cycling in business districts. Movement CVC 22107 requires cyclists to yield and signal before moving left or right. CVC 21656 specifies that slow-moving vehicles causing a queue of five or more vehicles behind them must turn off the roadway in order to allow the vehicles behind to pass them.
