State has a Far Right as Practicable Requirement

A cyclist traveling slower than other traffic must ride as close as practicable to the right-hand curb or edge of the roadway, except when passing, preparing to turn left, avoiding a hazard, or when the lane is too narrow to share safely with a motor vehicle.

Allows Two Abreast Riding

Arizona permits riding two abreast on a roadway; more than two abreast is restricted to paths or roadway portions set aside exclusively for bicycles.

Single File is Required

Arizona does not require single-file riding; cyclists may ride up to two abreast on a roadway.

Has a Safe Passing Law

Arizona requires drivers overtaking a bicycle to leave a safe distance of not less than three feet until safely past. A violation causing serious injury or death carries a civil penalty of up to $500 or $1,000 respectively, though that enhanced penalty does not apply if the cyclist was hit while riding in a travel lane with a passable bicycle lane or path available.

Helmets are required on the road

Arizona has no statewide bicycle helmet law for riders of any age. Some cities and towns have their own local helmet ordinances, typically for minors, under their local regulatory authority. Title 28, Chapter 3, Article 3 (§§ 28-811 to 28-819) is the article that governs the operation of bicycles, and no section in it imposes a helmet requirement.

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

Arizona does not require a cyclist to use a marked bicycle lane when one is available; a cyclist may lawfully use the adjacent travel lane instead, subject to the general right-side positioning rule.

Riders may use the sidewalks

Arizona's state traffic code does not itself address whether bicycles may be ridden on sidewalks; instead it gives local authorities the power to regulate bicycle operation generally, which cities and towns use to set their own sidewalk-riding rules (commonly prohibiting it in downtown/business districts while allowing it elsewhere). Whether sidewalk riding is allowed therefore depends on the specific municipality.

Does the Impeding Statute Apply to Bikes

Arizona requires a cyclist moving slower than traffic to stay near the right edge, but recognizes several exceptions (passing, preparing to turn left, avoiding hazards, and narrow lanes) that let a cyclist take the lane, so whether a cyclist must yield position to faster traffic depends on the situation.

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

Arizona has not adopted an Idaho-stop law. A bicyclist, like any other vehicle driver, must come to a full stop at a stop sign and obey traffic-control devices in the ordinary way.

Restrictions exist on e-bikes and usage

Arizona recognizes Class 1, 2, and 3 electric bicycles and gives e-bike riders the same rights and duties as bicycle riders, with no license, registration, or insurance requirement. Class 1 and 2 e-bikes may generally use bicycle paths unless a local authority prohibits it; Class 3 e-bikes are generally barred from bicycle and multi-use paths except on roadways or where a local authority specifically allows it.

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

Arizona does not follow contributory negligence. It applies pure comparative negligence: an injured cyclist's damages are reduced in proportion to their own share of fault, rather than barred outright, unless their conduct was intentional or willful.
