Cycling rules in Arizona
- Helmets
- No statewide helmet law for bicyclists; some cities and counties require helmets for riders under 18. (source)
- Passing distance
- Drivers overtaking a bicycle must leave a safe distance of at least 3 feet until safely past (ARS 28-735). (source)
- Sidewalk riding
- No statewide statute; sidewalk riding is governed by local city ordinances, so rules vary by community. (source)
- E-bikes
- Arizona uses the 3-class system (ARS 28-819). Class 1 and 2 may use bike/multiuse paths unless prohibited locally; Class 3 is restricted on paths unless adjacent to a road or locally allowed. E-bikes have the rights and duties of bicycles and need no registration, license, or insurance. (source)
- Lights/reflectors at night
- At night a bicycle must have a front white light visible at least 500 feet and a rear red reflector; a rear red light may be added but does not replace the reflector (ARS 28-817). (source)
- Direction / where to ride
- A cyclist moving slower than traffic must ride as far right as practicable, with exceptions for turns, hazards, and narrow lanes; no more than two abreast on the roadway (ARS 28-815). (source)
- Rights & duties
- Bicyclists on the roadway have the same rights and are subject to the same duties as motor-vehicle drivers, and must obey all traffic laws (ARS 28-812). Arizona has no stop-as-yield / 'Idaho stop' law. (source)
Cities and counties often add their own rules (for example, where you can ride on sidewalks or boardwalks). Check the local ordinance for the specific town you're visiting.
