Chris asked: If there are two lanes for each direction of traffic and no bike lanes, may one or two bicycles use the right whole lane?
It depends on the width of the lane. A narrow lane that meets the definition of “substandard-width lane” is one of the many exceptions to the “keep right” provision in the law. Usually, that is less than 14 feet. The normal lane in a multi-lane roadway is about 12 feet wide. In those lanes, a cyclist is not required to keep right.
In wide lanes, cyclists must keep right in many cases, but again, there are many exceptions.
The above makes common sense as it is unlawful to for a motorist to pass a cyclist within the same narrow lane, but it is legal to pass within the same lane in a wide lane.
See the posts under “Lane Width and Sharing” for more information.
See the posts under “Impeding Traffic” for information about riding two abreast.
