Arizona Motorcycle Helmet Law: What Riders Need to Know in 2026

What Arizona’s motorcycle helmet statute says

A.R.S. 28-964 says an operator or passenger of a motorcycle, all-terrain vehicle, or motor driven cycle who is under eighteen years of age must wear a protective helmet at all times in the appropriate manner. The statute also says the helmet must be safely secured while the person is operating or riding.

For an adult rider or passenger, that subsection does not impose the same age-based helmet requirement. That is a statement about the equipment rule in this statute, not a recommendation about the level of protection a person should choose for a particular ride. A current statute is the reliable place to check the wording, exceptions, and any later changes.

Arizona’s separate eyewear rule

The helmet question is only one part of the statute. A.R.S. 28-964 says an operator of a motorcycle, all-terrain vehicle, or motor driven cycle must wear protective glasses, goggles or a transparent face shield of a type approved by the director unless the vehicle is equipped with a protective windshield.

That wording treats protective eyewear and a helmet as different subjects. When looking at an individual motorcycle, read the statute and identify the actual equipment on the vehicle rather than assuming one item answers every equipment question.

Other equipment points in A.R.S. 28-964

Section 28-964 also addresses basic equipment. It says a motorcycle, all-terrain vehicle, and motor driven cycle must be equipped with a rearview mirror, seat, and footrests for the operator. A vehicle operated with a passenger must have a passenger seat and passenger footrests.

This is not a complete checklist for every vehicle, road, or rider. It is a plain-language summary of the equipment items in this specific statute. For the full rule, including exceptions and citation provisions, read the linked statute itself.

What the comparative-fault statute does and does not answer

A.R.S. 12-2505 says contributory negligence and assumption of risk are questions of fact for a jury. It also describes proportional reduction if a jury applies either defense. The statute’s wording is not a shortcut for deciding whether a particular piece of gear, injury, roadway event, or medical record matters in a specific situation.

That distinction is important after a crash. The applicable rule, the evidence, medical information, vehicle condition, and the questions raised by an insurer or another party can be different from one event to the next. A public article cannot determine those facts or tell a reader what an outcome will be.

Records to preserve after a motorcycle crash

Get appropriate medical care and follow the instructions you receive. When it is safe and practical, preserve the records and physical items that already exist. A dated, organized folder makes a later conversation more grounded and less dependent on memory.

• Original scene photos or video, including the roadway, lane layout, vehicle positions, visible damage, and any signs that were visible at the scene.
• The helmet, eyewear, clothing, and motorcycle equipment in their post-crash condition when practical, along with purchase or repair records you already have.
• Witness names and contact information, collision-report information, insurance correspondence, tow records, and repair documents.
• Medical instructions, appointment records, bills, work restrictions, and work records that exist independently of a claim.
• A dated timeline that separates what you observed directly from information learned later.

Do not alter evidence to make it fit a narrative and do not try to access another person’s private phone, account, vehicle system, or medical record. Preserve your own material and ask a qualified professional about lawful ways to identify records that may be relevant.

How to prepare for a useful first conversation

Bring the documents and facts you already have: the crash location, scene media, equipment information, report number, insurer correspondence, treatment dates, and a list of missing records. A private review can help identify the next practical question without treating a general statute as the answer to an individual event.
