Indiana has no statewide bicycle-helmet law. A handful of municipalities — including Carmel and Bloomington — encourage helmet use through public-safety campaigns but do not mandate it.
Indiana has no statewide statute that authorises or prohibits sidewalk cycling. Local governments regulate the practice under their general municipal authority; Indianapolis prohibits sidewalk riding in the Mile Square downtown core and Bloomington restricts it in the Kirkwood Avenue commercial district. Outside designated business districts, sidewalk cycling is generally tolerated.
Ind. Code § 9-30-5-1 and § 9-30-5-2 apply to anyone who operates a 'vehicle,' and § 9-13-2-196 defines vehicle to include bicycles. A bicycle OWI (operating while intoxicated) carries the same statutory penalty range as an auto OWI — a Class C misdemeanor on a first offense with up to 60 days in jail and a $500 fine — although the mandatory licence suspension only attaches if the rider holds an Indiana licence.

Red reflector on the rear of a type approved by the Bureau of Motor Vehicles, visible from a distance of 500 to 600 feet when directly in front of lawful upper-beam headlamps. A red rear lamp may be used in addition to the reflector.
Bicycles are prohibited on all Interstate highways in Indiana under INDOT policy and Ind. Code § 9-21-8-58, which authorises the Department to bar pedestrians, bicycles, and other slow-moving traffic from any controlled-access facility. Conventional US routes and state highways are open by default.
