Thomas asked: I was pulled over today and was told by local police that when a bike lane is available it must be used instead of vehicle roadway.
A bicycle is a vehicle under Florida statutes and bicycle operators have all the rights and duties of other drivers, with some limitations. Under some circumstances, they must use lanes marked for the use of bicycles. There are many exceptions. See the following post. Also you can click on “bike lanes” in the tag cloud for much more information about this subject.
