The laws that apply to bicyclists relate to two lane widths, narrow and wide.  A narrow lane is a substandard-width lane if a motor vehicle cannot travel safely side by side with a bicycle within the lane.  In such circumstances a bicyclist need no keep right and may legally impede other traffic

In a wide lane, usually a minimum of 14 feet, bicyclists may not ride two abreast and must keep right to avoid impeding other traffic unless travelling at the same speed or greater than other traffic, passing, preparing for a left turn or avoiding any unsafe or potentially unsafe condition.
