Bicycling regulations

A state regulation requires a bicycle on a Kentucky road to be operated in the same manner as a motor vehicle, with some exceptions. Riders must obey traffic signals, signs and the other rules of the road.

Where to ride

• Keep to the right, except to pass, to prepare for a left turn, to avoid a hazard, or where the lane is too narrow to share with a passing vehicle.
• Riding on the shoulder is allowed unless a law or ordinance prohibits it.
• Where a lane is marked for bicycles only, use it, with exceptions such as turning left, passing or avoiding a hazard.
• Ride no more than two abreast in a single lane, and do not impede the normal movement of traffic.
• Riding on a sidewalk is allowed unless a law or local ordinance prohibits it, and local rules vary. A rider on a sidewalk must yield to pedestrians and slow to walking speed when they are present.

Passing a bicycle

A driver overtaking a bicycle must move into the next lane to the left when there is more than one lane going the same direction and the move is reasonably safe. On a road with one lane in that direction, the driver must keep at least three feet between any part of the vehicle and the bicycle until safely past. If there is not room for three feet, the driver must use reasonable caution. A driver may cross the center line to pass a bicycle, even in a no-passing zone, only when the left side is clear far enough ahead to pass safely.

Lights, equipment and helmets

• At night and in low visibility, a front light visible for 500 feet and a red light or flashing red light visible for 500 feet to the rear.
• At all times on a road or shoulder, a red reflector or red light visible for at least 100 feet from the rear.
• Brakes that can stop the bicycle within 15 feet from 10 miles per hour on dry, level, clean pavement.
• A bell or horn is allowed, but a siren or whistle is not.

Neither the state bicycle statute nor the regulation requires a helmet. Violating the regulation carries a fine of $10 to $100.

Electric bicycles

The state bicycle regulation covers a device propelled primarily by human power and does not set out separate classes or rules for electric bicycles. A motorized bicycle that meets the legal definition of a moped is treated as a moped, and its operator must be at least 16 and hold a permit or license. Local governments may have their own rules for electric bicycles and scooters.
