Arizona’s year-round riding weather means heavy motorcycle traffic — and serious injuries when crashes happen. Arizona law protects riders’ right to recover even where helmet use or lane position is questioned.
What Arizona law says
A.R.S. § 12-542 — Two-year statute of limitations for injury claims.
A.R.S. § 12-2505 — Pure comparative fault — recovery is reduced by, but not barred by, a rider’s share of fault.
A.R.S. § 28-964 — Arizona’s helmet law requires riders under 18 to wear a helmet; adults are not required to, and not wearing one does not automatically bar recovery.
⏱ Key deadline
Most motorcycle-injury lawsuits must be filed within 2 years (A.R.S. § 12-542).
How motorcycle accident cases work in Maricopa County
Motorcycle injury claims follow the same at-fault framework as car crashes and are filed in Maricopa County Superior Court when not settled. Insurers frequently raise comparative fault, so documentation of the other driver’s negligence matters.
Frequently asked questions
Do I have to wear a helmet in Arizona?
Only riders under 18 are legally required to (A.R.S. § 28-964). Adult riders may choose not to.
Can I recover if I wasn’t wearing a helmet?
Yes. Lack of a helmet does not automatically bar recovery, though it may be raised under comparative fault depending on the injuries.
Are motorcycle injuries treated differently by insurers?
Insurers sometimes assume rider fault. Strong evidence of the other party’s negligence is key to a fair recovery.
