State has a Far Right as Practicable Requirement

Oklahoma requires a bicyclist riding slower than traffic to ride as close as is safe to the right-hand edge of the roadway, with exceptions for passing, turning left, avoiding hazards, and riding in a right-turn-only lane.

Allows Two Abreast Riding

Oklahoma allows riding no more than two abreast in a single lane on a roadway (more than two abreast is allowed only on paths or lanes set aside exclusively for bicycles), and riders two abreast may not impede the normal flow of traffic.

Single File is Required

Oklahoma does not require single-file riding; two abreast is expressly permitted in a single lane, subject to not impeding traffic flow.

Has a Safe Passing Law

Oklahoma requires a motorist overtaking a bicyclist to move to an adjacent lane when one is safely available, or otherwise to leave at least three feet of clearance; a motorist may also cross the centerline, including in a no-passing zone, to pass safely.

Helmets are required on the road

No statewide requirement exists for a bicyclist of any age to wear a helmet. Oklahoma does require helmets for riders under 18 on a motorcycle and under 18 on an all-terrain vehicle; some municipalities separately require helmets for minors on bicycles.

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

Oklahoma has no statewide law requiring a cyclist to use a bike lane where one is present. (A local ordinance could impose such a requirement in a specific city, but no such rule exists at the state level.)

Riders may use the sidewalks

State law does not directly address whether a bicyclist may ride on a sidewalk; it is left entirely to local ordinance, so the answer depends on the city or town. (Compare Oklahoma's separate statutes expressly authorizing sidewalk use for motorized scooters and electric personal assistive mobility devices, subject to local restriction.)

Does the Impeding Statute Apply to Bikes

Oklahoma's general slow-speed/impeding law applies only to motor vehicles, not bicycles. A narrower bicycle-specific rule does apply, though: riders going two abreast may not impede the normal flow of traffic.

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

Oklahoma has a statewide "stop as yield" law. A bicyclist approaching a stop sign may treat it as a yield sign, proceeding without a full stop if there is no immediate hazard. At a steady red light, a bicyclist must come to a complete stop first, but may then proceed through with caution once satisfied it is clear, and may turn right without stopping in most cases.

Restrictions exist on e-bikes and usage

Oklahoma defines three classes of electric-assisted bicycle by motor power and assisted speed. E-bikes are exempt from vehicle registration, insurance, and driver's-license requirements, may generally use bicycle and multiuse paths unless a local authority says otherwise, and Class 3 e-bikes carry an additional minimum operating age of 16 and a required speedometer.

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

Oklahoma does not follow pure contributory negligence. It uses modified comparative negligence: an injured cyclist can still recover damages as long as their own negligence is not greater than the combined negligence of the party or parties who caused the harm (a "greater than 50%" bar), with damages reduced by their own percentage of fault.
