State has a Far Right as Practicable Requirement

Kentucky's general "keep to the right" rule for slow-moving traffic (KRS 189.300) applies to bicycles because Kentucky's traffic code defines "vehicle" broadly, without excluding human-powered devices. A cyclist moving slower than other traffic must stay as close as practicable to the right, allowing faster vehicles free passage, unless road markings say otherwise.

Allows Two Abreast Riding

Kentucky has no statute that expressly permits or bars riding two abreast. Because the general keep-right rule (KRS 189.300(2)) requires a slow-moving vehicle — which includes a bicycle — to allow faster traffic "reasonably free passage," riding abreast is lawful only to the extent it does not block that passage; whether it is permitted in a given moment depends on traffic conditions.

Single File is Required

Kentucky does not require single-file riding by statute. Whether riding abreast is lawful in a given situation depends on whether it interferes with the "reasonably free passage" that KRS 189.300(2) requires slow-moving traffic, including bicycles, to allow faster vehicles.

Has a Safe Passing Law

Kentucky requires a motorist overtaking a bicycle to change lanes fully when a second lane is available and it is safe to do so, or otherwise to leave at least three feet of clearance until safely past the rider.

Helmets are required on the road

Kentucky has no statewide bicycle helmet requirement. The state's only statutory headgear mandate (KRS 189.285) applies specifically to motorcycles and mopeds, not to bicycles. Local ordinances may impose their own requirements.

If Bike Lanes are present, they are required ( except when unsafe )

Kentucky has no statute requiring cyclists to use a bike lane or path when one is provided; a rider may use the roadway generally, subject to the state's keep-right rule for slow-moving traffic.

Riders may use the sidewalks

Kentucky has no statewide statute that specifically permits or prohibits riding a bicycle on a sidewalk. Whether it is allowed depends on local ordinance, which varies by city and county.

Does the Impeding Statute Apply to Bikes

Unlike some neighboring states, Kentucky's impeding-traffic rule is not limited to motor vehicles: KRS 189.300(2) requires the operator of any slow-moving vehicle, bicycles included, to keep right and allow faster traffic free passage. This makes the impeding duty directly applicable to bicyclists as a matter of statutory text, not just general practice.

Whether cyclists may treat stop signs as yield signs (the "Idaho stop").

Kentucky has a "dead red" affirmative defense for signal delay, but it applies only to motorcycles, not bicycles. Kentucky has no stop-as-yield law of any kind for bicyclists; cyclists must stop at stop signs and red signals like any other vehicle operator.

Restrictions exist on e-bikes and usage

Kentucky has no statute that defines "electric bicycle" or imposes electric-bicycle-specific restrictions (no class system, no age limit, no path restriction). Kentucky has adopted rules for electric low-speed scooters, but these are a legally distinct category from bicycles or e-bikes.

Allows the concept of Contributory Negligence that allows any contributory fault resuls in 'no fault'

Kentucky follows pure comparative fault under Hilen v. Hays (1984), a court-made rule since the General Assembly has never enacted a general comparative-fault statute. An injured cyclist's damages are reduced in proportion to their own percentage of fault, but they may recover something even if found mostly at fault — there is no percentage threshold that bars recovery entirely.
