Helmet rules

Required under age
No statewide age requirement
Applies to passengers
Standard
Penalty
Kentucky has no statewide bicycle helmet law for any age. A handful of local ordinances exist - for example, Lexington-Fayette Urban County requires riders under 12 to wear a helmet - but enforcement is rare and there is no statewide penalty.

Sidewalk riding

Statewide rule
Defers to local rules
Notes
Kentucky has no statewide statute permitting or prohibiting sidewalk cycling. KRS 189.287 defines a bicycle as a vehicle and the regulatory framework lives in 601 KAR 14:020, but neither addresses sidewalks. Cities and counties set their own rules: Louisville prohibits sidewalk riding in business districts, Lexington restricts it in the central business district, and many smaller towns have no rule at all.

DUI on a bicycle

Applies to bicycles
No
Separate cycling DUI statute
No
BAC limit
Penalty
Kentucky's DUI statute (KRS 189A.010) applies only to anyone in physical control of a 'motor vehicle.' Bicycles are vehicles under KRS 189.287 but are not motor vehicles, so a cyclist cannot be charged with DUI. Public-intoxication (KRS 222.202) and reckless-conduct charges may still apply to a clearly impaired rider on a public road.
Statute
