I’ve added a link to Indiana’s bicycle laws in the Online Resources section, but I’ll put the link here as well: http://www.in.gov.
Here are two sections that I think are particularly noteworthy:
A person riding a bicycle upon a roadway has all the rights and duties under this article that are applicable to a person who drives a vehicle…
A person riding a bicycle upon a roadway may not ride more than two (2) abreast except on paths or parts of roadways set aside for the exclusive use of bicycles.
If you’ve never read Indiana’s cycling laws, I’d say it is definitely worth the few minutes it takes to look them over.
