Motorcycle Accident Lawyer in Arizona

Arizona's statute of limitations for motorcycle accident claims is two years from the date of the crash under A.R.S. § 12-542. Arizona follows pure comparative negligence under A.R.S. § 12-2505, which means no percentage of fault bars your recovery — even if a jury assigns you 70% responsibility, you still collect 30% of your damages. That is a more claimant-friendly rule than Texas's or Pennsylvania's 51% modified bar, but it makes the fault-allocation fight critical. Every percentage point the insurer pins on the rider is a percentage point subtracted from the check. In the Phoenix metro area, where I-17 and I-10 converge and year-round riding conditions create heavy motorcycle traffic, left-turning vehicles violating a rider's right of way remain the single most common crash scenario. Documenting the at-fault driver's conduct — intersection geometry, traffic camera footage, the vehicle's event data recorder — is not optional. It is the case.

Arizona's 2022 lane-filtering law, A.R.S. § 28-903(F), makes Arizona one of only a handful of states that authorize any form of between-lane riding. But the authorization is the narrowest in the country. The statute permits a two-wheeled motorcycle to overtake and pass another vehicle only when three conditions are met simultaneously: the street has at least two adjacent traffic lanes in the same direction, the posted speed limit is 45 mph or less, and the motorcycle is traveling at 15 mph or less. This is lane filtering of stopped traffic — not the California-style lane splitting of moving traffic. If the rider was doing 16 mph, or the road was posted at 50, or traffic was moving instead of stopped, the maneuver falls outside the statutory safe harbor. Insurance adjusters know the three-prong test and will argue any marginal deviation. A local Arizona motorcycle attorney documents the posted speed limit, the rider's speed via EDR or dashcam, and the traffic state at the moment of the maneuver to keep the filtering defense intact.

Arizona's helmet law under A.R.S. § 28-964(A) requires helmets only for operators and passengers under 18. Adults 18 and older ride without a legal helmet obligation — which means helmet non-use by an adult rider is not a traffic violation. But that does not prevent the defense from introducing it as evidence of comparative fault. Arizona has no primary-source appellate decision flatly barring helmet evidence, so the admissibility question is analyzed under the pure comparative fault framework of A.R.S. § 12-2505. In practice, an insurer arguing that an unhelmeted adult rider's head injuries were more severe than they would have been with a helmet is making a damages-mitigation argument, not a liability argument. The distinction matters: it cannot shift who caused the crash, but it can reduce the damages award. Eye protection — protective glasses, goggles, or a transparent face shield — is required for all operators regardless of age unless the motorcycle has an approved windshield.

Motorcycle injuries are catastrophic by nature — road rash requiring skin grafts, orthopedic fractures, traumatic brain injury, spinal cord damage. Arizona's minimum liability insurance of 25/50/15 is grossly inadequate for these injuries. A $25,000 per-person bodily injury limit barely covers one surgery. A serious Arizona motorcycle case requires stacking every available coverage layer: the at-fault driver's liability policy, the rider's own uninsured/underinsured motorist coverage (Arizona insurers must offer UM/UIM under A.R.S. § 20-259.01 — if the rider did not reject it in writing, the coverage likely exists), MedPay, umbrella policies, and — when a commercial vehicle was involved — the employer's policy. If a government vehicle caused the crash, the 180-day notice requirement under A.R.S. § 12-821.01 and the one-year lawsuit deadline under A.R.S. § 12-821 apply instead of the standard two-year window. Miss that 180-day notice and the claim is permanently dead regardless of how clear the liability.
